We aimed to conduct a comprehensive meta-analysis to compare the outcomes of angioembolisation and pelvic packing in patients with pelvic trauma.METHODS: We conducted a systematic search of electronic information sources, including MEDLINE; EMBASE; CINAHL; the CENTRAL; the World Health Organization International Clinical Trials Registry; Clinical Trials.gov; ISRCTN Register, and bibliographic reference lists. The primary outcome was defined as mortality. Combined overall effect sizes were calculated using randomeffects models. Results are reported as the odds ratio(OR) and 95% confidence interval(CI).RESULTS: We identified 3 observational studies reporting a total of 120 patients undergoing angioembolisation(n=60) or pelvic packing(n=60) for pelvic trauma. Reporting of the Injury Severity Score(ISS) was variable, with higher ISS in the pelvic packing group. The risk of bias was low in two studies, and moderate in one. The pooled analysis demonstrated that angioembolisation did not significantly reduce mortality in patients with pelvic trauma compared to surgery(OR=1.99; 95% CI= 0.83–4.78, P=0.12). There was mild between-study heterogeneity(I^2=0%, P=0.65).CONCLUSION: Our analysis found no significant difference in mortality between angioembolisation and pelvic packing in patients with traumatic pelvic haemorrhage. The current level of evidence in this context is very limited and insufficient to support the superiority of a treatment modality. Future research is required.展开更多

The treatment modalities for bone tumors vary with the individual lesion, but in general surgical excision is the treatment of choice with other adjunctive therapies. However, surgery for many bone tumors is complex due to several factors including tumor bulk, vascularity, vicinity to vital structures and potentially inaccessible location of the lesion. Transarterial Embolisation (TAE) is one of the important adjuvant treatment modalities and in some cases it may be the primary and curative treatment. Preoperative TAE has proved to be effective in both primary and metastatic bone tumors. It reduces tumor vascularity and intraoperative blood loss, the need for blood transfusion and associated complications, allows better definition of tissue planes at surgery affording more complete excision, and hence reduced recurrence. Preoperative chemoEmbolisation has also been shown to increase the sensitivity of some tumors to subsequent chemotherapy and radiotherapy. There are several techniques and embolic agents available for this purpose, but the ultimate aim is to achieve tumor devascularization. In this review, we discuss the techniques including the choice of embolic agent, application to individual lesions and potential complications.展开更多

The reported cases are mostly hemangiomas fed either by the hepatic artery itself or by one of its branches. We present two unique hepatic AVM cases in the presence of congenital heart defects in which the AVM was not fed by the hepatic arterial system. Transcatheter coil embolisation was successfully carried out in both of them by using non-detachable Gianturco coils. Complete occlusion was achieved without any sequel.展开更多

The device allows for endoluminal reconstruction across the aneurysm neck but is permeable enough that flow is preserved across the pressure gradients into sidebranch arteries. In spite of higher rates of aneurysm occlusion, there is lack of data concerning medium to long-term clinical and imaging results. Methods: This study was a prospective single center analysis of complications, imaging results, and medium term clinical outcomes after PED treatment of intracranial aneurysms. We included cases over a 17-month period in a tertiary interventional neuroradiology center. We collected data on demographics, vascular risk factors, clinical presentation, angiographic results post treatment, angiographic follow-up and clinical follow-up. Results: Thirty-three patients were included, 25 females and 8 males, with mean age of 55 years;3 presented with acute subarachnoid hemorrhage and 30 for elective treatment. Thirty-seven aneurysms were treated: 35 Internal Carotid Artery (ICA), 1 basilar trunk fusiform, and 1 vertebral artery intradural dissecting aneurysms. No deaths have occurred. Five patients suffered transient neurological complications (15%). Overall aneurysm occlusion was demonstrated in 85% of patients at the end of one year. Discussion:?Overall, the technique of flow diversion and endoluminal reconstruction differs greatly from the established endosaccular packing techniques of standard coiling, balloon remodeling, or stent assisted coiling. Our midterm follow-up confirms that, the rates of clinically significant complications compare favorably with published data on stent assisted coiling, potentially making these devices a truly revolutionizing technique.展开更多

HCC often occurs on top of a cirrhotic liver. The prognosisis determined by several factors; tumour extension, alpha-fetoprotein(AFP) concentration, histologic subtype of the tumour, degree of liver dysfunction, and the patient's performance status. HCC prognosis is strongly correlated with diagnostic delay. To date, no ideal screening modality has been developed. Analysis of recent studies showed that AFP assessment lacks adequate sensitivity and specificity for effective surveillance and diagnosis. Many tumour markers have been tested in clinical trials without progressing to routine use in clinical practice. Thus, surveillance is still based on ultrasound(US) examination every 6 mo. Imaging studies for diagnosis of HCC can fall into one of two main categories: routine non-invasive studies such as US, computed tomography(CT), and magnetic resonance imaging, and more specialized invasive techniques including CT during hepatic arteriography and CT arterial portography in addition to the conventional hepatic angiography. This article provides an overview and spotlight on the different diagnostic modalities and treatment options of HCC.展开更多

文摘Pulmonary tumour thrombotic microangiopathy(PTTM)is a rare but under-recognised cause of rapidly progressive pulmonary hypertension(PH)and cor pulmonale,characterised by diffuse obstruction of small pulmonary arteries by metastatic tumour cells.These tumour emboli lead to obstructive intimal proliferation and in situ thrombosis within the pulmonary vasculature,further compromising the overall permeability of the pulmonary vascular bed and exacerbating PH.[1]The clinical and imaging manifestations of PTTM often overlap with those of other causes of PH,including chronic thromboembolic PH,pulmonary veno-occlusive disease and pulmonary capillary haemangiomatosis,often leading to diagnostic delays.
文摘Hepatocellular carcinoma(HCC) is ranked as the 5th common type of cancer worldwide and is considered as the 3rd common reason for cancer-related deaths. HCC often occurs on top of a cirrhotic liver. The prognosisis determined by several factors; tumour extension, alpha-fetoprotein(AFP) concentration, histologic subtype of the tumour, degree of liver dysfunction, and the patient's performance status. HCC prognosis is strongly correlated with diagnostic delay. To date, no ideal screening modality has been developed. Analysis of recent studies showed that AFP assessment lacks adequate sensitivity and specificity for effective surveillance and diagnosis.

This article provides an overview and spotlight on the different diagnostic modalities and treatment options of HCC.
