The present review aims to clarify the appropriateness of the size category ＂giant＂ for liver heman- gioma. DATA SOURCES： We reviewed the reports on the categoriza- tion of hemangioma published between 1970 and 2014. The number of hemangiomas, size criteria, mean and range of hemangioma sizes, and number of asymptomatic and symp- tomatic patients were investigated in patients aged over 18 years. Liver hemangiomas were divided into four groups： 〈5.0 cm, 5.0-9.9 cm, 10.0-14.9 cm and 〉15.0 cm in diameter. Inclu- sion criteria were noted in 34 articles involving 1972 （43.0%） hemangiomas （〉4.0 cm）. RESULTS： The patients were divided into the following groups： 154 patients （30.0%） with hemangiomas less than 5.0 cm in diameter （small）, 182 （35.5%） between 5.0 cm and 9.9 cm （large）, 75 （14.6%） between 10.0 and 14.9 cm （giant）, and 102 （19.9%） more than 15.0 cm （enormous）. There were 786 （39.9%） asymptomatic patients and 791 （40.1%） symptomatic patients. Indications for surgery related to symptoms were reported in only 75 （3.8%） patients. Operations including 137 non-anatomical resection （12.9%） and 469 enudeation （44.1%） were undearly related to size and symptoms.CONCLUSIONS： The term ＂giant＂ seems to be justified for liver hemangiomas with a diameter of 10 cm. Hemangiomas categorized as ＂giant＂ are not indicated for surgery. Surgery should be performed only when other symptoms are apparent.展开更多

A 35 year-old woman presented to hospital with main complaint of epigastric pain and abdominal fullness. An enhanced computed tomography scan revealed a massive liver tumor in right lobe about 150 mm in size. There was contrast enhancement at the periphery of the mass consistent with a cavernous hemangioma. She underwent right hepatectomy. Histologically, it was diagnosed as a cavernous hemangioma. And also, hemangiomatous lesions were scattered around the Glisson’s capsule on the back ground liver. These hemangiomatous lesions were not recognized preoperatively. Even if we couldn’t diagnose hemangiomatosis around the main giant hemangioma preoperatively, we need to take enough surgical margins because the giant hemangioma has the potential to have small hemangiomatous lesions around the tumor. We reported right hepatectomy for giant cavernous hemangioma with diffuse hepatic hemangiomatosis without an extrahepatic lesion in an adult.展开更多

METHODS: The clinical data from 28 patients, who underwent hepatic resection requiring intraoperative autologous transfusion with the cell-saver apparatus, were analyzed retrospectively. The tumors in the 28 patients involved the proximal hepatic veins and inferior vena cava. The diameters of these hemangiomas ranged from 12x15 cm to 18-40 cm. All patients had varying degrees of THVE. ' RESULTS: The 28 patients with hemangioma received integrated resection and recovered. One patient had rupture of tumors resulting in massive hemorrhage of 6000 ml during liver resection; 4 patients had blood transfusions of 400-800 ml; the other 23 patients had no blood transfusion. Only 6 patients underwent the Pringle maneuver with resection. The other 22 patients underwent THVE during the liver resection. The interval of THVE was 5-30 minutes (mean 16 minutes). CONCLUSIONS: Intraoperative autologous transfusion during modified, normal-temperature THVE for extracapsular resection of huge hepatic cavernous hemangioma is feasible.展开更多

The patient had a history of a giant hepatic cavernous hemangioma. Emergency exploratory laparotomy was performed for suspected intra-abdominal bleeding with abdominal compartment syndrome, and more than 4 liters of blood and blood clots were removed. An active bleeding laceration （5 cm） of a hepatic cavernous hemangioma was detected in segment III of the liver. The bleeding was controlled by sutures, Teflon patches and tamponade. The abdomen was closed temporarily using the vacuum-assisted method. Because of the presence of persistent fresh blood through abdominal drainage at a rate of 〉1 L/h, splenectomy was performed to control the bleeding again by sutures and Teflon patches. Finally, the abdomen was closed using a biologic mesh. The patient was discharged home 30 days after trauma. Bleeding of trauma-caused hepatic hemangioma is rare, but splenic injury due to blunt abdominal trauma is common. An in-depth investigation is necessary to avoid second intervention.展开更多

METHODS: To observe the relation of cavernous hemangioma of the liver to the hepatic artery and portal vein, we performed serial selective hepatic arteriography in 22 patients. Five patients after ligation of the right hepatic arteries underwent portography and liver staining by in jection of methylene blue into the portal veins and 2 patients had hepatic specimens resected, which were made into a model cast by filling the hepatic veins (yellow) and portal venous branches (blue) with methyl methacrylate after vascular lavage. RESULTS: Serial selective hepatic arteriography showed that hepatic arteries and hemangioma were displayed simultaneously, and that hemangioma was supplied by one to numerous arterial branches. In the portal phase of portography, contrast medium failed to enter the tumor and the intrahepatic branches of the portal vein were pushed aside by the tumor; in the liver parenchymal phase, however, the tumor appeared to be a low-density area. Hepatic arteriography and portography revealed that the fistula between the artery and portal vein may not be existed. The liver stained with methylene blue showed that the normal hepatic parenchyma could be stained with deep blue; in contrast, the tumor was not stained at all. The casting specimens showed that the eroded tumor left a round vacant area because of its total shedding, and no blue stained branches of the portal vein extended into the tumor. CONCLUSION: Blood supply of CHL may originate from the hepatic artery.展开更多

We report on the diagnosis and treatment of a retroperitoneal hemangioma which had uncommonly invaded into both the pancreas and duodenum, thus requiring a pylorus preserving pancreaticoduodenectomy (PpPD). A 36-year-old man presented to our hospital with abdominal pain. An enhanced computed tomography scan without contrast enhancement revealed a 12 cm × 9 cm mass between the pancreas head and right kidney. Given the high rate of malignancy associated with retroperitoneal tumors, surgical resection was performed. Intraoperatively, the tumor was inseparable from both the duodenum and pancreas and PpPD was performed due to the invasive behavior. Although malignancy was suspected, pathological diagnosis identified the tumor as a retroperitoneal cavernous hemangioma for which surgical resection was the proper diagnostic and therapeutic procedure. Reteoperitoneal cavernous hemangioma is unique in that it is typically separated from the surrounding organs. However, clinicians need to be aware of the possibility of a case, such as this, which has invaded into the surrounding organs despite its benign etiology. From this case, we recommend that combined resection of inseparable organs should be performed if the mass has invaded into other tissues due to the hazardous nature of local recurrence. In summary, this report is the first to describe a case of retroperitoneal hemangioma that had uniquely invaded into surrounding organs and was treated with PpPD.展开更多

METHODS Ⅰ. Origin of blood supply of CHL: portovenography, hepatic arteriography and portal vein staining were performed in 5 patients. Two casts of hepatic blood vessels from resected specimen were observed. Ⅱ. Clinical data: Among 75 patients (30 males, 45 females, aged 25～57 years with a mean of 37 4). 56 were of solitary type (44 on the right lobe, 12 on the left with 4 having intraparenchymatoma) and 19 were of multiple type (9 on the right, 2 the left, 8 whole liver). Twenty two patients were treated by sclerosis, 50 by embolization via hepatic artery and 3 were excised. RESULTS In 5 cases with portography, the contrast medium did not enter the tumor, the tumor appeared as low denty area and the intrahepatic branches of portal vein were pushed aside. In 5 cases with portal vein staining, the normal liver parenchyma was stained deep blue, and the tumor was not stained. The tumor area appeared as a round vacant cavity in 2 specimen casts. In 72 patients treated with sclerosis a or embolization via hepatic artery or through interventional method, the tumors diminished by 10%～30% in diameter and no tumors grew larger. CONCLUSION The blood supply of CHL originates from the hepatic artery. Tumors treated with sclerosis and emblization decreased in size or got fiberized.展开更多

METHODS: A total of 97 patients with pathologically confirmed CH in the orbit were examined with axial and coronal CT scan, and axial, coronal, sagittal, and enhanced fat suppression MRI scan. CT and MRI findings and intraoperative adhesion degrees were retrospectively analyzed. RESULTS: There were 47 patients with slight adhesion, for whom CT and MRI showed round masses with well defined margins in the extraocular muscles; 14 patients with mild adhesion, for whom CT and MRI revealed irregular masses with unclear boundary between CH and the optic nerve in coronal images, and emissary veins in the posterior region of masses in contrast-enhanced images; 36 patients with severe adhesion, for whom CT and MRI exhibited an irregular or ovoid mass filling the orbital apex, or showed distorted and even spiky margins in the posterior region of masses in contrast enhanced images at the presence of a transparent triangle between the mass and the orbital apex. CONCLUSION: Preoperative CT and MRI aid in accurate diagnosis, selection of the surgical approach, and assessment of the adhesion degree and surgical risks for CH.展开更多

METHODSFifteen consecutive patients (11 females and 4 males; mean age 40.93 years; age range 13-63 years) with cavernous sinus hemangiomas (CSH) who underwent examination between November 2008 and May 2016 were included for the analysis. MRI, clinical and surgical findings of each patient was retrospectively reviewed. DWI were also analysed and mean-apparent diffusion coefficient (ADC) value was calculated. Eleven patients underwent surgical removal of the lesion and 2 patients had biopsy only. Diagnosis of CSH was confirmed histologically in 13 patients. RESULTSEleven patients (73%) presented with headaches and 10 (66%) had cranial nerve involvement. Extra cavernous sinus extension was noted in 14 (94%). Surgery was performed in 13 (87%) and post-operative radiation was given to 4 (28%) patients. Thirteen patients remained asymptomatic on follow up. Three conspicuous imaging features were highly suggestive of the diagnosis: Lack of diffusion restriction (100%), homogeneous hyperintensity on T2 weighted image sequences (93.3%) and intense post-contrast enhancement (100%). The mean ADC was 1.82 × 10<sup>-3</sup> ± 0.2186 cm<sup>2</sup>/s. CONCLUSIONT1-weighted hypointensity with homogeneous hyperintensity on T2-weighted sequences, intense enhancement and absence of hemosiderin within the lesion on GRE sequence favour the diagnosis. Facilitated diffusion on DWI differentiates CSH from other solid cavernous sinus lesions and significantly improves the diagnostic accuracy, a critical factor for planning surgery.展开更多

Right and caudate lobectomies were done in 27 cases, right hemihepatectomies in 5 cases, right upper segmentectomies in 7 cases, right posterior lobec-tomies in 7 cases, extended left and caudate lobectomies in 10 cases, and caudate lobectomies in 6 cases. The blood transfusion requirement during operation was 1 400 ml on average. All did well postoperatively during a follow up of 4 - 84 months.Conclusion It is safe and feasible to resect giant hepatic cavernous hemangioma following dissection of the third porta hepatis. During operation the key step is dissection of the short hepatic veins.展开更多

文摘OBJECTIVE: To investigate the origin of blood supply to cavernous hemangioma of the liver (CHL). METHODS: To observe the relation of cavernous hemangioma of the liver to the hepatic artery and portal vein, we performed serial selective hepatic arteriography in 22 patients. Five patients after ligation of the right hepatic arteries underwent portography and liver staining by in jection of methylene blue into the portal veins and 2 patients had hepatic specimens resected, which were made into a model cast by filling the hepatic veins (yellow) and portal venous branches (blue) with methyl methacrylate after vascular lavage. RESULTS: Serial selective hepatic arteriography showed that hepatic arteries and hemangioma were displayed simultaneously, and that hemangioma was supplied by one to numerous arterial branches. In the portal phase of portography, contrast medium failed to enter the tumor and the intrahepatic branches of the portal vein were pushed aside by the tumor; in the liver parenchymal phase, however, the tumor appeared to be a low-density area. Hepatic arteriography and portography revealed that the fistula between the artery and portal vein may not be existed. The liver stained with methylene blue showed that the normal hepatic parenchyma could be stained with deep blue; in contrast, the tumor was not stained at all. The casting specimens showed that the eroded tumor left a round vacant area because of its total shedding, and no blue stained branches of the portal vein extended into the tumor. CONCLUSION: Blood supply of CHL may originate from the hepatic artery.
文摘A retroperitoneal hemangioma is a rare disease. We report on the diagnosis and treatment of a retroperitoneal hemangioma which had uncommonly invaded into both the pancreas and duodenum, thus requiring a pylorus preserving pancreaticoduodenectomy (PpPD). A 36-year-old man presented to our hospital with abdominal pain. An enhanced computed tomography scan without contrast enhancement revealed a 12 cm × 9 cm mass between the pancreas head and right kidney. Given the high rate of malignancy associated with retroperitoneal tumors, surgical resection was performed. Intraoperatively, the tumor was inseparable from both the duodenum and pancreas and PpPD was performed due to the invasive behavior. Although malignancy was suspected, pathological diagnosis identified the tumor as a retroperitoneal cavernous hemangioma for which surgical resection was the proper diagnostic and therapeutic procedure. Reteoperitoneal cavernous hemangioma is unique in that it is typically separated from the surrounding organs. However, clinicians need to be aware of the possibility of a case, such as this, which has invaded into the surrounding organs despite its benign etiology. From this case, we recommend that combined resection of inseparable organs should be performed if the mass has invaded into other tissues due to the hazardous nature of local recurrence. In summary, this report is the first to describe a case of retroperitoneal hemangioma that had uniquely invaded into surrounding organs and was treated with PpPD.
文摘Objective To analyze the imaging character and surgical therapy of cavernous hemangiomas in cavernous sinus(CSHs).Methods From 2001 to 2008,13 patients with CSHs were surgically treated in our department. The diameters of CSHs varied from 3. 5 cm to 6. 0 cm. Results All the patients were operated on with no mortality.
文摘AIM To investigate the source of blood supply of carvenous hemangioma of liver (CHL) and provide a feasibile treatment for CHL via hepatic artery. METHODS Ⅰ. Origin of blood supply of CHL: portovenography, hepatic arteriography and portal vein staining were performed in 5 patients. Two casts of hepatic blood vessels from resected specimen were observed. Ⅱ. Clinical data: Among 75 patients (30 males, 45 females, aged 25～57 years with a mean of 37 4). 56 were of solitary type (44 on the right lobe, 12 on the left with 4 having intraparenchymatoma) and 19 were of multiple type (9 on the right, 2 the left, 8 whole liver). Twenty two patients were treated by sclerosis, 50 by embolization via hepatic artery and 3 were excised. RESULTS In 5 cases with portography, the contrast medium did not enter the tumor, the tumor appeared as low denty area and the intrahepatic branches of portal vein were pushed aside. In 5 cases with portal vein staining, the normal liver parenchyma was stained deep blue, and the tumor was not stained. The tumor area appeared as a round vacant cavity in 2 specimen casts. In 72 patients treated with sclerosis a or embolization via hepatic artery or through interventional method, the tumors diminished by 10%～30% in diameter and no tumors grew larger. CONCLUSION The blood supply of CHL originates from the hepatic artery. Tumors treated with sclerosis and emblization decreased in size or got fiberized.
文摘AIM: To assess features of cavernous hemangioma (CH) in the orbit revealed by CT and MRI and summarize prediction of preoperative CT and MRI for the adhesion degree of CH in the orbit. METHODS: A total of 97 patients with pathologically confirmed CH in the orbit were examined with axial and coronal CT scan, and axial, coronal, sagittal, and enhanced fat suppression MRI scan. CT and MRI findings and intraoperative adhesion degrees were retrospectively analyzed. RESULTS: There were 47 patients with slight adhesion, for whom CT and MRI showed round masses with well defined margins in the extraocular muscles; 14 patients with mild adhesion, for whom CT and MRI revealed irregular masses with unclear boundary between CH and the optic nerve in coronal images, and emissary veins in the posterior region of masses in contrast-enhanced images; 36 patients with severe adhesion, for whom CT and MRI exhibited an irregular or ovoid mass filling the orbital apex, or showed distorted and even spiky margins in the posterior region of masses in contrast enhanced images at the presence of a transparent triangle between the mass and the orbital apex. CONCLUSION: Preoperative CT and MRI aid in accurate diagnosis, selection of the surgical approach, and assessment of the adhesion degree and surgical risks for CH.
文摘AIMTo elucidate the clinical, magnetic resonance imaging (MRI), pathological features of these lesions and asses the incremental value of diffusion-weighted imaging (DWI) in diagnosing them. METHODSFifteen consecutive patients (11 females and 4 males; mean age 40.93 years; age range 13-63 years) with cavernous sinus hemangiomas (CSH) who underwent examination between November 2008 and May 2016 were included for the analysis. MRI, clinical and surgical findings of each patient was retrospectively reviewed. DWI were also analysed and mean-apparent diffusion coefficient (ADC) value was calculated. Eleven patients underwent surgical removal of the lesion and 2 patients had biopsy only. Diagnosis of CSH was confirmed histologically in 13 patients. RESULTSEleven patients (73%) presented with headaches and 10 (66%) had cranial nerve involvement. Extra cavernous sinus extension was noted in 14 (94%). Surgery was performed in 13 (87%) and post-operative radiation was given to 4 (28%) patients. Thirteen patients remained asymptomatic on follow up. Three conspicuous imaging features were highly suggestive of the diagnosis: Lack of diffusion restriction (100%), homogeneous hyperintensity on T2 weighted image sequences (93.3%) and intense post-contrast enhancement (100%). The mean ADC was 1.82 × 10<sup>-3</sup> ± 0.2186 cm<sup>2</sup>/s. CONCLUSIONT1-weighted hypointensity with homogeneous hyperintensity on T2-weighted sequences, intense enhancement and absence of hemosiderin within the lesion on GRE sequence favour the diagnosis. Facilitated diffusion on DWI differentiates CSH from other solid cavernous sinus lesions and significantly improves the diagnostic accuracy, a critical factor for planning surgery.
文摘Objective To establish a novel and safe operation technique for the resection of giant hepatic cavernous hemangiomas involving the retro-hepatic vena cava.Methods After ligating the hepatic artery of affected lobe, the short hepatic veins at the third porta hepatis were dissected and ligated individually to separate the tumor from the retrohepatic vena cava, followed by the resection of the tumor under intermittent interruption of the porta hepatis.Results A total of 62 giant hepatic cavernous hemangiomas were successfully resected without hepatic vascular exclusion. Right and caudate lobectomies were done in 27 cases, right hemihepatectomies in 5 cases, right upper segmentectomies in 7 cases, right posterior lobec-tomies in 7 cases, extended left and caudate lobectomies in 10 cases, and caudate lobectomies in 6 cases. The blood transfusion requirement during operation was 1 400 ml on average. All did well postoperatively during a follow up of 4 - 84 months.Conclusion It is safe and feasible to resect giant hepatic cavernous hemangioma following dissection of the third porta hepatis. During operation the key step is dissection of the short hepatic veins.

文摘BACKGROUND Primary abdominal and retroperitoneal cavernous hemangioma is a vascular tumor and rarely seen in the clinic.Due to the lack of specific imaging features,retroperitoneal cavernous hemangioma cannot be diagnosed accurately.Some symptoms may develop with the enlargement of lesion volume or the occurrence of complications such as rupture or oppression.We report here a special case who was admitted with chronic abdominal pain.Admission examination suggested a retroperitoneal lymphatic duct cyst.Laparoscopic resection of the retroperitoneal mass was performed,and histological examination confirmed retroperitoneal cavernous hemangioma.CASE SUMMARY The patient was a 43-year-old Tibetan woman with intermittent left lower abdominal pain and discomfort 3 years ago.Ultrasonography revealed a cystic mass in the retroperitoneum with clear boundaries,internal septa,and no blood flow signal.Computed tomography(CT)and magnetic resonance imaging(MRI)showed an irregular space-occupying mass in the retroperitoneum,and retroperitoneal lymphatic cyst was considered.Plain CT scanning showed multiple cystlike hypo-intense shadows in the retroperitoneum,partially fused into a mass,and no obvious enhancement was found on enhanced scanning.MRI showed multiple irregular clump-like long T1 and long T2 signal shadows above the pancreas,within which linear short T2 signal shadows were seen.Diffusionweighted imaging sequence showed hypo-signal shadows,without obvious enhancement on enhanced scanning.Ultrasound,CT,and MRI all suggested the possibility of retroperitoneal lymphatic cyst.However,the patient was finally diagnosed with retroperitoneal cavernous hemangioma by pathological examination.CONCLUSION Retroperitoneal cavernous hemangioma is a benign lesion,and it is difficult to make a diagnosis preoperatively.Surgical resection may be the only treatment,which not only allows histopathological confirmation as a diagnostic purpose and excludes any risk of malignancy,but also avoids invasion of adjacent tissues,oppression,and other complications as a therapeutic goal.
