To evaluate treatment of infrarenal abdominal aortic aneurysm (AAA) with a new endoluminal stent-graft.
In 26 male patients, straight or bifurcated nitinol stents covered with woven Dacron graft material were implanted to treat eccentric saccular AAA (n = 3) or AAA involving the bifurcation and common iliac arteries (n = 23), with follow-up from 8 days to 8 1/2 months.
Implantation was technically successful in all but one of the 26 (96%) patients (leak of the stent-graft for more than 3 months necessitated implantation of an additional covered stent). In seven of the 26 patients, minor residual perfusion persisted immediately after implantation, but complete thrombosis occurred within 7 days. Five procedure-related complications occurred: distal embolization (n = 2); local hematoma, which necessitated surgery (n = 1); acute hepatic failure due to gastric bleeding, in a patient with liver cirrhosis (n = 1); and stent-graft occlusion due to emboli originating from the left atrium (n = 1).
Exclusion of AAA from circulation was feasible, safe, and clinically effective with the new stent-graft.
评估一种新型腔内支架型人工血管治疗肾下腹主动脉瘤（AAA）的效果。
对26例男性患者植入由编织涤纶人工血管材料覆盖的直型或分叉型镍钛合金支架，以治疗偏心囊状AAA（n = 3）或累及分叉和髂总动脉的AAA（n = 23），随访时间为8天至8个半月。
26例患者中除1例（96%）外，植入技术均成功（支架型人工血管渗漏超过3个月，需植入额外的覆膜支架）。26例患者中有7例在植入后立即存在轻微残余灌注，但在7天内完全血栓形成。发生了5例与手术相关的并发症：远端栓塞（n = 2）；局部血肿，需手术治疗（n = 1）；1例肝硬化患者因胃出血导致急性肝衰竭（n = 1）；源于左心房的栓子导致支架型人工血管闭塞（n = 1）。
使用新型支架型人工血管将AAA排除在循环之外是可行、安全且临床有效的。
