目的：既往报告证实了经腔放置血管内移植物（TPEG）治疗腹主动脉瘤的初步技术成功。然而，主动脉和腹主动脉段的大小的长期变化是未知的。本研究的目的是确定主动脉尺寸在几个层面的计算机断层扫描（CT）扫描后1年TPEG.Methods：34例患者接受TPEG与i年CT扫描。患者被分为三组：第一组，无移植物周围渗漏;第二组，在第一年内密封的早期移植物周围渗漏;第三组，持续性移植物周围渗漏。主动脉的小直径和大直径，周长和面积进行了测量，在四个位置：腹腔主动脉，近端颈部，最大动脉瘤的大小，和远端neck.Results：有32名男性和两名女性，平均年龄为73+/-8岁。I组有20例患者（58%），II组和III组各有7例患者（21%）。总平均动脉瘤内径从植入时的4.79 ± 0.68 cm降至1年时的4.39 ± 0.86 cm（p
Purpose: Previous reports demonstrate initial technical success with transluminally placed endovascular grafts (TPEG) for the treatment of abdominal aortic aneurysms. However, long-term changes in the size of the aorta and aneurysmal segments are unknown. The purpose of this study was to determine aortic dimensions at several levels by computed tomographic (CT) scans 1 year after TPEG.Methods: Thirty-four patients underwent TPEG with i-year CT scans. Patients were divided into three groups: group I, no perigraft leak; group II, early perigraft leak that sealed during the first year; and group III, persistent perigraft leak. Aortic minor and major diameters, perimeter, and area were measured at four locations: the celiac aorta, proximal neck, maximal aneurysm size, and distal neck.Results: There were 32 men and two women, with a mean age of 73+/-8 years. In group I there were 20 patients (58%), and groups II and III had seven patients (21%) each. The overall mean aneurysm minor diameter decreased from 4.79+/-0.68 cm at implantation to 4.39+/-0.86 cm at 1 year (p
