To determine the feasibility of use of a self-expanding nitinol stent covered with polyester fabric in long iliac stenoses.
In 10 patients with 12 iliac artery stenoses (6-10 cm long [mean, 7.5 cm]), a Cragg endoluminal graft was placed percutaneously after failure of percutaneous transluminal angioplasty.
At angiography after implantation of 15 Cragg endoluminal grafts, patency was restored and the dissection flap was eliminated without any residual stenosis in all cases. At 1-13-month follow-up (mean, 7 months), eight patients were asymptomatic, with a mean ankle-brachial index of 0.90 +/- 0.15 (standard deviation). Arterial rupture occurred in one patient, with thrombosis of the artery with the stent within 1 day. In one patient, tight restenosis was seen at the proximal part of the stent. In another patient, moderate restenosis was seen at the distal junction of the prosthesis with the native artery, but restenosis did not occur within the stent. The 6-month primary patency rate of the stent graft was 80%.
In long iliac artery stenoses, the deployment of the Cragg endoluminal graft is feasible and no short-term complications were seen.
确定使用覆盖聚酯织物的自膨式镍钛诺支架治疗长段髂动脉狭窄的可行性。
10例患者共12处髂动脉狭窄（长度6 - 10厘米[平均7.5厘米]），经皮腔内血管成形术失败后，经皮置入Cragg腔内移植物。
植入15个Cragg腔内移植物后行血管造影，所有病例均恢复通畅，夹层瓣消失，无残余狭窄。随访1 - 13个月（平均7个月），8例患者无症状，平均踝肱指数为0.90±0.15（标准差）。1例患者发生动脉破裂，支架置入动脉内1天内出现血栓形成。1例患者在支架近端出现严重再狭窄。另1例患者在假体与天然动脉的远端连接处出现中度再狭窄，但支架内未发生再狭窄。支架移植物的6个月原发性通畅率为80%。
在长段髂动脉狭窄中，置入Cragg腔内移植物是可行的，且未见短期并发症。
