Gastric antral vascular ectasia (GAVE) is an uncommon but often severe cause of upper gastrointestinal (GI) bleeding, responsible of about 4% of non-variceal upper GI haemorrhage. The diagnosis is mainly based on endoscopic pattern and, for uncertain cases, on histology. GAVE is characterized by a pathognomonic endoscopic pattern, mainly represented by red spots either organized in stripes radially departing from pylorus, defined as watermelon stomach, or arranged in a diffused-way, the so called honeycomb stomach. The histological pattern, although not pathognomonic, is characterized by four alterations:vascular ectasia of mucosal capillaries, focal thrombosis, spindle cell proliferation and fibrohyalinosis, which consist of homogeneous substance around the ectatic capillaries of the lamina propria. The main differential diagnosis is with Portal Hypertensive Gastropathy, that can frequently co-exists, since about 30% of patients with GAVE co-present a liver cirrhosis. Autoimmune disorders, mainly represented by Reynaud's phenomenon and sclerodactyly, are co-present in about 60% of patients with GAVE; other autoimmune and connective tissue disorders are occasionally reported such as Sjogren's syndrome, systemic lupus erythematosus, primary biliary cirrhosis and systemic sclerosis. In the remaining cases, GAVE syndrome has been described in patients with chronic renal failure, bone marrow transplantation and cardiac diseases. The pathogenesis of GAVE is still obscure and many hypotheses have been proposed such as mechanical stress, humoural and autoimmune factors and hemodynamic alterations. In the last two decades, many therapeutic options have been proposed including surgical, endoscopic and medical choices. Medical therapy has not clearly shown satisfactory results and surgery should only be considered for refractory severe cases, since this approach has significant mortality and morbidity risks, especially in the setting of portal hypertension and liver cirrhosis. Endoscopic therapy, particularly treatment with Argon Plasma Coagulation, has shown to be as effective and also safer than surgery, and should be considered the first-line treatment for patients with GAVE-related bleeding. 展开更多

Gastric antral vascular ectasia(GAVE) accounted for 4% of non-variceal gastrointestinal hemorrhage.Even though unclear pathogenesis,GAVE often associated with chronic renal failure,autoimmune diseases and cirrhosis.Asymptomatic lesions were reasonably not to treated.The treatment options for GAVE are nonendoscopic and endoscopic treatments.For the pharmacological treatment,some success were reported for the use of octreotide,thalidomide and tranexamic acid.While the endoscopic treatment is the mainstay for treatment of symptomatic lesions.The endoscopic ablative therapies such as argon plasma coagulation was reported with good clinical outcomes.However,these treatment options had some limitation due to the need of special equipment and multiple sessions needed to control the bleeding.We reported another treatment option using the routine-achievable instrument such as endoscopic band ligation as an initial treatment which also provided a good treatment outcome and less sessions. 展开更多

Gastric antral vascular ectasia(GAVE) may cause gastrointestinal bleeding(GIB). The treatment of GAVE relies on endoscopic approaches such as electrocoagulation(argon plasma coagulation, laser therapy, heater probe therapy, radiofrequency ablation), cryotherapy, and band ligation. In refractory cases, antrectomy may be considered. In the event of an associated cirrhosis and portal hypertension, it has been suggested that antrectomy could be an option, provided the mortality risk isn't considered too great. We report the case of a 67-year-old cirrhotic patient who presented with GAVE related GIB, unresponsive to multiple endoscopic treatments. The patient had a good liver function(model for end-stage disease 10). After a multidisciplinary meeting, a transjugular intrahepatic portosystemic shunt(TIPS) procedure was performed, in order to treat the cirrhosis associated ascites. The outcome was successful. An antrectomy was then performed, with no recurrence of GIB and no transfusion need during three months of follow up. In this case, the TIPS procedure achieved a complete ascites regression, allowing a safer surgical treatment of the GAVE-related GIB. 展开更多

AIM: To investigate in patients with functional dyspepsia (FD) after an every-day meal whether (1) gastrointestinal (GI) and extra-GI symptoms had any relation with the degree of antral volume, (2) the onset of postprandial symptoms was associated with, and may predict, delayed gastric emptying. METHODS: In 94 symptomatic FD patients, antral volume variations and gastric emptying were assessed with ultrasonography after a 1050 kcal meal. Symptoms were evaluated with a standardized questionnaire. The association of GI and extra-GI symptoms with antral volumes and gastric emptying were estimated with logistic regression analysis. RESULTS: Forty percent of patients did not report any symptoms after a meal. Compared to the healthy controls, the antrum was more distended in patients throughout the entire observation period and 37 (39.4%) patients had delayed gastric emptying. Only postprandial drowsiness was associated with antral volume variations (AOR = 1.42; P < 0.001) and with delayed gastric emptying (AOR = 3.59; P < 0.03). CONCLUSION: In FD patients, GI symptoms are neither associated with antral distension nor with gastric emptying. Drowsiness is associated with antral distension and delayed gastric emptying. The onset of drowsiness is preceded by an increment of antral distension and the duration of the symptom appears to be related to the persistence of antral distension. 展开更多

Gastric antral vascular ectasia(GAVE) has been recognized as one of the important causes of occult and obscure gastrointestinal bleeding.The diagnosis is typically made based on the characteristic endoscopic features,including longitudinal row of flat,reddish stripes radiating from the pylorus into the antrum that resemble the stripes on a watermelon.These appearances,however,can easily be misinterpreted as moderate to severe gastritis.Although it is believed that capsule endoscopy(CE) is not helpful for the study of the stomach with its large lumen,GAVE can be more likely to be detected at CE rather than conventional endoscopy.CE can be regarded as "physiologic" endoscopy,without the need for gastric inflation and subsequent compression of the vasculature.The blood flow of the ecstatic vessels may be diminished in an inflated stomach.Therefore,GAVE may be prominent in CE.We herein describe a case of active bleeding from GAVE detected by CE and would like to emphasize a possibility that CE can improve diagnostic yields for GAVE. 展开更多

To evaluate long-term endoscopic resolution and recurrence rate of gastric antral vascular ectasia (GAVE) after argon plasma coagulation (APC) treatment. METHODSThis was an IRB-approved retrospective single center study that included patients endoscopically treated for GAVE between 1/1/2008 to 12/31/2014. The primary and secondary end points of the study were rate of endoscopic resolution of GAVE after APC treatment and recurrence rate of GAVE after endoscopic resolution, respectively. Endoscopic resolution of GAVE was defined as no endoscopic evidence of GAVE after treatment with APC. Recurrence of GAVE was defined as endoscopic reappearance of GAVE after prior resolution. RESULTSTwenty patients met the study criteria. Median age (range) of the patients was 59.5 years (42-74 years). GAVE was associated with underlying cirrhosis in 16 (80%) patients. Indications for initial esophagogastroduodenoscopy (EGD) included hematemesis and/or melena (9/20, 45%), iron deficiency anemia (6/20, 30%), screening or surveillance of varices (4/20, 20%), and occult gastrointestinal bleeding (1/20, 5%). The patients were treated with a total of 55 APC sessions (range 1-7 sessions). Successful endoscopic resolution of GAVE was achieved in 8 out of 20 patients (40%). There was no correlation between number of treatment sessions and GAVE treatment success (P = NS). Recurrence of GAVE was noted on a subsequent EGD in 2 out of 8 patients (25%) with prior endoscopic resolution of GAVE. Median follow-up period for the study population was 627 d (range 63-1953 d). CONCLUSIONEndoscopic resolution rate of GAVE was low (40%) with a 25% recurrence rate after treatment with APC. These rates suggest that APC treatment of GAVE may not be optimal in many circumstances. 展开更多

The treatments for GAVE include surgery, endoscopy and medical therapies. Here, we report an unusual case of GAVE. A 72-year-old man with a three-month history of recurrent melena was diagnosed with GAVE. Endoscopy revealed the classical &#x0201c;watermelon stomach&#x0201d; appearance of GAVE and complete pyloric involvement. Melena reoccurred three days after argon plasma coagulation treatment, and the level of hemoglobin dropped to 47 g/L. The patient was then successfully treated with distal gastrectomy with Billroth II anastomosis. We propose that surgery should be considered as an effective option for GAVE patients with extensive and severe lesions upon deterioration of general conditions and hemodynamic instability. 展开更多

Objectives: To clarify the optimal length of the antral cuff (LAC) in patients after pylorus-preserving gastrectomy (PPG), we investigated relationships between LAC and postgastrectomy disorder (PGD) such as postprandial abdominal fullness (PAF), and between LAC and gastric empting function (GEF) in PPG patients. Background: The main cause of PGD in PPG patients has been considered to be LAC. Relationships between LAC and PGD and GEF in PPG patients are still unknown. Methods: Of 50 patients who underwent PPG in our hospital from January 2001 to December 2015 were divided into 2 groups [Group A, short LAC of 1.5 to 2.5 cm (n = 24);Group B, long LAC of 2.6 to 3.5 cm (n = 26)]. The relationships among LAC, PGD, and GEF were retrospectively studied. Results: LAC was clearly shorter in group A than group B (P < 0.01). PAF, appetite and food consumption per meal were clearly more favorable in group B than in group A (P < 0.01, respectively). Symptomatic reflux esophagitis (RE), early dumping syndrome, decreased percent body weight for pre-illness, endoscopic RE and endoscopic gastritis in the remnant stomach were more frequent in group A than group B. Gastric stasis in the remnant stomach was clearly more frequent in group A than group B (P < 0.01). GEF with the solid diet in group A was clearly more delayed than in group B (P Conclusions: Patients with a short LAC showed worse postoperative QOL and delayed GEF with the solid diet compared with a long LAC. 展开更多

BACKGROUND Accurate detection of gastric antral vascular ectasia(GAVE)is critical for proper management of cirrhosis-related gastrointestinal bleeding.However,endoscopic diagnosis of GAVE can be challenging when GAVE overlaps with severe portal hypertensive gastropathy(PHG).AIM To determine the added diagnostic value of virtual chromoendoscopy to high definition white light for real-time endoscopic diagnosis of GAVE and PHG.METHODS We developed an I-scan virtual chromoendoscopy criteria for diagnosis of GAVE and PHG.We tested our criteria in a cross-sectional cohort of cirrhotic adults with GAVE and PHG when high-definition white light endoscopy(HDWLE)diagnosis was in doubt.We then compared the accuracy of I-scan vs HDWLE alone to histology.RESULTS Twenty-three patients were included in this study(65.2%Caucasians and 60.9%males).Chronic hepatitis C was the predominant cause of cirrhosis(43.5%)and seven adults(30.4%)had confirmed GAVE on histology.I-scan had higher sensitivity(100%vs 85.7%)and specificity(75%vs 62.5%)in diagnosing GAVE compared to HDWLE.This translates into a higher,albeit not statistically significant,accuracy of I-scan in detecting GAVE compared to HDWLE alone(82%vs 70%).I-scan was less likely to lead to an accurate diagnosis of GAVE in patients on dialysis(P<0.05)and in patients with elevated creatinine(P<0.05).Iscan had similar accuracy to HDWLE in detecting PHG.CONCLUSION This pilot work supports that virtual chromoendoscopy may obviate the need for biopsies when the presence of GAVE is in doubt.Larger studies are needed to assess the impact of virtual chromoendoscopy on success of endoscopic therapy for GAVE. 展开更多

Her past history included autoimmune hepatitis. Esophagogastroduodenal endoscopy was performed to investigate the bleeding source and revealed multiple linear gastric vascular malformations in the antrum and cardia, compatible with Gastric antral vascular ectasia (GAVE). Endoscopic ablation was carried out with the tip of the hot biopsy forceps without opening at soft coagulation mode of 80W. The patient tolerated the procedure well and there were no complications associated with endoscopic therapies. After two sessions of endoscopic ablation her anemia improved to around 10 g/dL, an increase of 3.6 g/dL. Various endoscopic treatments have been described to manage GAVE. The most popular is argon plasma coagulation (APC), although APC is associated with over-distension induced by the argon plasma gas. To avoid over-distension and to reduce the abdominal discomfort/pain of this patient,we have used hot biopsy forceps instead of APC. Our case suggests that this procedure is effective, easy and convenient,as no special equipment or skill is necessary. 展开更多

AIM To study and describe patients who underwent treatment for gastric antral vascular ectasia(GAVE) with different endoscopic treatment modalities.METHODS We reviewed patients with GAVE who underwent treatment at University of Alabama at Birmingham between March 1, 2012 and December 31, 2016. Included patients had an endoscopic diagnosis of GAVE with associated upper gastrointestinal bleeding or iron deficiency anemia.RESULTS Seven out of 15 patients had classic watermelon description for GAVE, 1/15 with diffuse/honeycomb pattern and 6/15 with nodular GAVE per EGD description. Seven out of 15 patients required multimodal treatment. Four out of six of patients with endoscopically nodular GAVE required multimodal therapy. Overall, mean pre-and post-treatment hemoglobin(Hb) values were 8.2 ± 0.8 g/dL and 9.7 ± 1.6 g/dL, respectively(P ≤ 0.05). Mean number of packed red blood cells transfusions before and after treatment was 3.8 ± 4.3 and 1.2 ± 1.7(P ≤ 0.05), respectively.CONCLUSION Patients with nodular variant GAVE required multimodal approach more frequently than non-nodular variants. Patients responded well to multimodal therapy and saw decrease in transfusion rates and increase in Hb concentrations. Our findings suggest a multimodal approach may be beneficial in nodular variant GAVE. 展开更多

Objective To evaluate the efficacy of anti-Müllerian hormone(AMH), antral follicle count(AFC) and follicle-stimulating hormone(FSH) for predicting the number of oocytes retrieved in in-vitro fertilization/intracytoplasmic sperm injection(IVF/ICSI)cycles.Methods In this retrospective study, a total of 122 infertile women were divided into two groups: group A, 〈35 years(n=71); group B, ≥35 years(n=51). AMH and FSH were determined on 2-5 d of the early menstrual cycle. AFC was tested on the second day of the menstrual cycle before the start of stimulation.Results Group B had higher FSH levels compared with group A(8.2±3.5 IU/L vs 6.8±2.4 IU/L, P〈0.05). However, levels of AMH and AFC in group B were lower than those of group A(AMH: 4.2±3.5 μg/L vs 2.7±2.7 μg/L; AFC: 9.0±3.9 vs 5.4±3.3, P〈0.05). The number of oocyte retrieved in the two groups was not significantly different(11.5±6.8 vs 9.6±6.9, P〉0.05). The level of AMH was more strongly correlated with the number of oocytes retrieved than that of AFC or FSH level. The strengths of the correlation degrees were AMH level, AFC, and FSH level in turn(r=0.600, 0.511,-0.369).Conclusion AMH would be a useful predictor for ovarian response. 展开更多

Objective:To investigate the effects of different concentrations of N-acetylcysteine on follicular growth and morphology,as well as on viability,levels of reactive oxygen species(ROS)and meiotic progression of oocytes from in vitro cultured bovine early antral follicles.Methods:Isolated early antral follicles(about 500μm)were cultured in TCM-199+alone or supplemented with 1.0,5.0 or 25.0 mM N-acetylcysteine at 38.5℃with 5%CO_(2) for 8 days.Follicle diameters were evaluated at day 0,4 and 8 of culture.At the end of culture,the levels of ROS,chromatin configuration and viability(calcein-AM and ethidium homodimer-1 staining)were investigated in the cumulus-oocyte complexes.Comparisons of follicle diameters between treatments were performed.Data on percentages of morphologically normal follicles,growth rates and chromatin configuration in different treatments were compared.Results:An increase in follicular diameters after culture in all treatments was observed,except for follicles cultured with 25.0 mM N-acetylcysteine.Fluorescence microscopy showed that oocytes cultured in all treatments were stained positively with calcein AM,and that 5.0 mM N-acetylcysteine reduced fluorescence for ethidium homodimer-1.Intracellular levels of ROS in oocytes from follicles cultured with 1.0 mM N-acetylcysteine showed a significant reduction compared to other treatments.The presence of N-acetylcysteine in culture medium did not influence the rates of oocyte at the germinal vesicle stage.Conclusions:N-acetylcysteine at concentrations of 1.0 and 5.0 mM reduces ROS levels and staining for ethidium homodimer-1 in in vitro cultured follicles,respectively,while 25.0 mM N-acetylcysteine decreases follicular growth and the percentages of continuously growing follicles. 展开更多

Objective: To study the effects of highly selective vagotomy plus resection of antral mucosa (HSV+RAM) or highly selective vagotomy (HSV) alone on the motility function of the pyloric antrum. Methods: 48 patients with duodenal ulcer were studied. 18 dogs were employed as experimental animals. 20 patients were operated on with HSV and 28 with HSV+RAM. The frequency of gastric evacuation and the amplitude of electrogastrography were determined 4 to 6 months after operation. 18 dogs were divided into the control group, HSV group and HSV+RAM group. The time of gastric evacuation, antral myoelectric activity and antral pressure were determined in the dogs 4 to 6 months after operation. The preoperative findings of the patients and the control dogs served as the control. Results: After operation, barium meal revealed that the shape of the stomach and duodenum was normal and the gastric peristalsis was clearly visible in human patients and experimental dogs. In the HSV+RAM group of dogs, the initial evacuation time was (5.0+0.06) min and the time of complete evacuation was (4.0+0.4) h after food-taking, which were similar to those of the control and the HSV group of dogs (P>0.05). The frequency of the antral myoelectric action potential was (3.11+0.65) cycles/min in the dog HAS+RAM group and the frequency of electrogastrography was (3.25+0.75) cycles/min in the human HSV+RAM group, which were significantly lower than those of the control and the dog and human HSV groups (P<0.05). Injection of pentagastrin in dogs and food-taking in human beings significantly increased the antral pressure and the amplitude and frequency of electrogastrography. Conclusion: The findings of this study suggest that the motility function of the reconstructed pyloric antrum in the HSV+RAM group of both the experimental dogs and human patients approaches to the normal even though there is a decrease of antral myoelectric frequency. It is suggested that HSV+RAM should be the first choice for the surgical management of duodenal ulcer. 展开更多

Objective:To speculate which of the following parameters:antral follicle count(AFC),anti-Müllerian hormone(AMH),follicle-stimulating hormone(FSH)and age can be used as a predictor of ovarian response to gonadotropin-releasing hormone(GnRH)antagonist stimulation multiple-dose protocol in women under 45 years,and to determine the cutoff value of these parameters and their correlations for predicting low and high ovarian response.Methods:This prospective study included 462 women with the mean age of(29.3±6.5)years.All women were subjected to the GnRH antagonist stimulation multiple-dose protocol.On the second day of the menstrual cycle,ultrasonography was conducted to determine AFC in both ovaries.Peripheral blood samples were collected to evaluate the level of estradiol,FSH,luteinizing hormone,prolactin,thyroid-stimulating hormone,and AMH.The women were divided into three groups:low response(AHH<1 ng/mL,n=173),normal response(AMH=1.0-3.5 ng/mL,n=175),and high response(AMH>3.5 ng/mL,n=114).Results:A significant decrease was found in the age and FSH level in the high response group compared to other groups(P<0.001).Conversely,a significant increase was shown in AMH,estradiol on human chorionic gonadotropin(hCG)day,AFC,mature oocytes,fertilized oocytes,and embryos transferred in the high response group compared to the other two groups(P<0.001).The receiver operating characteristic(ROC)curves demonstrated that AFC and AMH had the highest accuracy,followed by basal FSH level and age in the prediction of low ovarian reserves(P<0.001)with cutoff values of≤4.50 and≤0.95 for AFC and AMH,respectively.Moreover,the ROC analysis showed that AFC had the highest accuracy,followed by AMH level and age in the prediction of high ovarian reserves with a cutoff value of≥14.50,≥3.63,and≤27.50 years,respectively(P<0.01).A significant decrease was observed in women's age,estradiol level,and oocyte fertilization rate in pregnant women compared to non-pregnant women(P<0.001).Additionally,significant negative correlations were found between the AFC,the number of mature oocytes,fertilized oocytes,embryos transferred,and the age of pregnant women(P<0.001).Conclusions:AFC and AMH predict low and high ovarian response to GnRH antagonist stimulation multiple-dose protocol in women under 45 years. 展开更多

METHODSWe reviewed our endoscopy database seeking to identify patients in whom a GAW was visualized among 24640 esophagogastroduodenoscopies (EGD) over a seven-year period (2006-2013) at a single tertiary care center. The diagnosis of GAW was suspected during EGD if aperture size of the antrum did not vary with peristalsis or if a &ldquo;double bulb&rdquo; sign was present on upper gastrointestinal series. Confirmation of the diagnosis was made by demonstrating a normal pylorus distal to the GAW. RESULTSWe identified 34 patients who met our inclusion criteria (incidence 0.14%). Of these, five patients presented with gastric outlet obstruction (GOO), four of whom underwent repeated sequential balloon dilations and/or needle-knife incisions with steroid injection for alleviation of GOO. The other 29 patients were incidentally found to have a non-obstructing GAW. Age at diagnosis ranged from 30-87 years. Non-obstructing GAWs are mostly incidental findings. The most frequently observed symptom prompting endoscopic work-up was refractory gastroesophageal reflux (n = 24, 70.6%) followed by abdominal pain (n = 11, 33.4%), nausea and vomiting (n = 9, 26.5%), dysphagia (n = 6, 17.6%), unexplained weight loss, (n = 4, 11.8%), early satiety (n = 4, 11.8%), and melena of unclear etiology (n = 3, 8.82%). Four of five GOO patients were treated with balloon dilation (n = 4), four-quadrant needle-knife incision (n = 3), and triamcinolone injection (n = 2). Three of these patients required repeat intervention. One patient had a significant complication of perforation after needle-knife incision. CONCLUSIONEndoscopic intervention for GAW using balloon dilation or needle-knife incision is generally safe and effective in relieving symptoms, however repeat treatment may be needed and a risk of perforation exists with thermal therapies. 展开更多

BACKGROUND Gastric antral vascular ectasia(GAVE)has diverse associations and presumed causes,which include liver cirrhosis,chronic kidney disease,and autoimmune disease.This heterogeneity of underlying disorders suggests that the pathogenesis of GAVE may be variable.AIM To compare the clinical features and long-term outcomes of GAVE according to endoscopic patterns and etiologies.METHODS The medical records and endoscopic images of 23 consecutive patients diagnosed with GAVE by endoscopy at Yeungnam University Hospital from January 2006 to December 2020 were retrospectively reviewed.Patients were allocated to cirrhosis(16 patients)and non-cirrhosis groups(7 patients).GAVE subtypes,as determined by endoscopy,were categorized as punctate(a diffuse,honeycomb-like appearance,17 patients)or striped(a linear,watermelon-like appearance,6 patients).RESULTS All GAVE patients with cirrhosis(16/16,100%)had a punctate pattern by endoscopy,whereas the majority of patients(6/7,85.7%)without cirrhosis had a striped pattern(P<0.001).Overt GAVE bleeding(10/23,43%)was significantly more common in the non-cirrhosis group than in the cirrhosis group(6/7,85.7%vs 4/16,25.0%;P=0.019),and more common in the striped group than in the punctate group(5/6,83.3%vs 5/17,29.4%;P=0.052).However,mean numbers of admissions due to GAVE bleeding and argon plasma coagulation(APC)sessions to address overt bleeding were similar in the cirrhosis and non-cirrhosis groups and in the punctate and striped groups.All patients with GAVE bleeding were successfully treated by APC,and no patient died from GAVE-related blood loss during a median follow-up of 24 mo.CONCLUSION Punctate-type GAVE is strongly associated with liver cirrhosis,and GAVE patients without cirrhosis tend to be more prone to overt bleeding.However,the presence of cirrhosis and endoscopic patterns did not influence long-term clinical courses or outcomes in cases of overt bleeding. 展开更多

Gastric antral vascular ectasia (GAVE) is a rare clinical disease which can cause recurrent upper gastrointestinal (GI) tract bleeding. It is responsible for about 4% of non-variceal upper GI haemorrhages. As one of the vascular diseases that happened in stomach, GAVE was also named as watermelon stomach (WS) for its characteristic endoscopic performance. Compared with portal hypertensive gastropathy (PHG) which with similar performances under endoscopy but often appeared as the result of portal hypertension, the etiology of GAVE is unknown. Recent years with further research it received several presumptions according to its histopathological features. Here we will introduce the disease systematically through two cases. 展开更多

The alveolar antral artery resides lateral to the maxillary sinus and can lead to complications in sinus lift surgery. Traditional approaches that decrease intraoperative bleeding into the surgical field include vessel preservation using multiple bony windows or neutralizing the vessel at the surgical site. Unfortunately, these methods are technique sensitive, time intensive, and may lead to hemosinus and graft loss. The variable distance from the crest of the alveolar ridge and vessel diameter further complicates pre-operative planning. This paper discusses the anatomical features of the alveolar antral artery, techniques for clinical assessment, and current management strategies. We then describe a novel protocol to manage the alveolar antral artery in sinus lift procedures via tamponade of the vessel at a proximal site. This method is faster than those described in the literature, does not require any additional equipment or expertise, and aims to improve long-term graft predictability by decreasing the risk of sinus membrane perforation. The alveolar antral artery is an under-reported source of surgical complications and warrants further research. 展开更多

Objective:To study the effects of preconceptional thyroid-stimulating hormone(TSH)levels on antral follicle count(AFC)and pregnancy outcomes in a firstin vitro fertilization(IVF)/intracytoplasmic sperm injection(ICSI)cycle.Methods:A retrospective cohort study was conducted to explore the effects of preconceptional TSH levels on AFC and pregnancy outcomes in 1340 patients.The patients were divided into three groups:group 1,0.55≤TSH<2.5μIU/mL(n=868);group 2,2.5≤TSH<4.0μIU/mL(n=334);and group 3,TSH≥4.0μIU/mL(n=138).Results:There were significant differences in AFC(P=0.002),number of zygotes(P=0.008),and fertilization rate(P=0.015)among the three groups.Among the three groups,there were no obvious differences in live birth(P=0.559),high-quality embryo(P=0.108),or clinical pregnancy(P=0.939)rates.Binary logistics regression analysis showed that TSH correlated with AFC when TSH was≥4μIU/mL(P=0.033);however,TSH levels had no effect on live birth or clinical pregnancy rate.Conclusions:Although the preconceptional TSH level negatively related with AFC,number of zygotes,and fertility rate,especially when TSH was>4μIU/mL,TSH was not an independent factor on the live birth rate among fertile women undergoing their first IVF/ICSI-embryo transfer treatment.The effect of TSH levels on couples undergoing assisted reproductive technology requires further investigation. 展开更多
