Methods All medical records of deaths from the West Branch of the Chinese People＇s Liberation Army （PLA） General Hospital were retrospectively re- viewed, for the period of January 1, 2006 to December 31, 2015. Cases in which autopsies had been performed were identified and further analyzed. The numbers and detailed characteristics of patients who had PEs were noted. Prophylactic measures, along with diagnosis and treatment of PE, were recorded, if performed. Results During the 10-year period, 1057 patients died in the study hospital and 278 necrop- sies were performed （autopsy rate： 26.3%）. Nine patients were found to have PE （3.2%）, and in seven of these patients （2.5%）, the PE was considered to be fatal. Embolisms were found in the trunk and bilateral main branches of the pulmonary artery tree in all seven of the fatal PE cases. Right intracardiac thrombosis was detected in five of the nine PE patients （55.6%）. All patients with PE had been hospitalized in medical departments, and only one had undergone surgery during hospitalization. Antemortem prophylaxis was performed in two of the nine PE cases （22.2%）. None of the 9 patients had received a clinical diagnosis of PE before death. Conclusions The incidence of and death rate associated with PE may vary among different races and regions. Continuous monitoring of PE by means of necropsy in certain representative medical institutions is necessary.展开更多

Aggressive treatment with early endoscopic hemostasis is essential for a favourable outcome. In as many as 12%-17% of patients,endoscopy is either not available or unsuccessful. Endovascular therapy with selective catheterization of the culprit vessel and injection of embolic material has emerged as an alternative to emergent operative intervention in high-risk patients. There has not been a systematic literature review to assess the role for embolotherapy in the treatment of acute upper gastrointestinal bleeding from gastroduo-denal ulcers after failed endoscopic hemostasis. Here,we present an overview of indications,techniques,and clinical outcomes after endovascular embolization of acute peptic-ulcer bleeding. Topics of particular relevance to technical and clinical success are also discussed. Our review shows that transcatheter arterial embolization is a safe alternative to surgery for massive gastroduodenal bleeding that is refractory to endoscopic treatment,can be performed with high technical and clinical success rates,and should be considered the salvage treatment of choice in patients at high surgical risk.展开更多

Methods: The data of 43 patients hospitalized consecutively with traumatic intractable carotid cavernous fistulas (TICCF) were analyzed. Therapeutic occlusion of ICA was performed on 39 cases and BOT was only performed on the remaining 4 cases. Our assessment consisted of: (1) angiographic evaluation of collateral circulation with or without BOT of ICA, and (2) evaluation of clinical tolerance to therapeutic occlusion of ICA with hypotensive challenge for 30 minutes. Complications of BOT and therapeutic occlusion of ICA were also analyzed retrospectively. Results: Complications related to BOT occurred in 1 case (2.3%) without causing permanent deficits. Complications related to therapeutic occlusion of ICA occurred in 4 cases (10%), including 1 technical (2.5%), 2 temporary (5%) and 1 permanent (2.5%) deficit. There was no fistula recurrence or mortality. Conclusions: BOT of ICA is safe and economical. The reliability of the results is almost the same compared with that of other more complicated methods of assessing therapeutic occlusion of ICA. And it is easy to treat TICCF with therapeutic occlusion of ICA.展开更多
