Abstract

A 68-year-old woman presenting with gastrointestinal bleeding (hematocrit 19.3%) and in a critical clinical condition (American Society of Anesthesiologists grade 4) from a giant superior mesenteric artery pseudoaneurysm (196.0 x 131.4 mm) underwent emergency endovascular treatment. The arterial tear supplying the pseudoaneurysm was excluded using a 5.0 mm diameter and 31 mm long monorail expanded polytetrafluoroethylene (ePTFE)-covered self-expanding nitinol stent. Within 6 days of the procedure, a gradual increase in hemoglobin levels and a prompt improvement in the clinical condition were observed. Multislice CT angiograms performed immediately, 5 days, 30 days and 3 months after the procedure confirmed the complete exclusion of the pseudoaneurysm.

摘要

一名68岁女性因巨大肠系膜上动脉假性动脉瘤（196.0×131.4mm）出现胃肠道出血（血细胞比容19.3%），临床状况危急（美国麻醉医师协会4级），接受了紧急血管内治疗。使用直径5.0mm、长度31mm的单轨膨体聚四氟乙烯（ePTFE）覆膜自膨式镍钛合金支架排除了供应假性动脉瘤的动脉撕裂口。术后6天内，观察到血红蛋白水平逐渐升高，临床状况迅速改善。术后即刻、5天、30天和3个月进行的多层CT血管造影证实假性动脉瘤已完全排除。
