To report results of primary stent placement for treatment of chronic iliac artery occlusions.
The authors placed 154 primary stents in 103 patients with iliac artery occlusions of at least 3 months duration. Mean length of the occluded segments was 5.1 cm. All patients had symptoms, with claudication or trophic changes. Mean ankle-arm index at rest was 0.48. Follow-up included angiography, Doppler ultrasound, and clinical examination.
Ninety-nine patients demonstrated clinical improvement, with relief or improvement of claudication. Complications that required percutaneous or surgical intervention occurred in six patients; minor complications occurred in another six. Embolization occurred in five patients. Primary patency was 87% after 1 year, 83% after 2 years, and 78% after 4 years; secondary patency was 94%, 90%, and 88% at 1 year, 2 years, and 4 years, respectively.
Primary stent placement should be the treatment of choice in unilateral chronic iliac artery occlusion.
报告原发性支架置入术治疗慢性髂动脉闭塞的结果。
作者对103例髂动脉闭塞至少3个月的患者置入了154个原发性支架。闭塞段的平均长度为5.1厘米。所有患者均有症状，表现为间歇性跛行或营养改变。静息时平均踝臂指数为0.48。随访包括血管造影、多普勒超声和临床检查。
99例患者临床症状改善，间歇性跛行缓解或改善。6例患者出现需要经皮或手术干预的并发症；另外6例出现轻微并发症。5例患者发生栓塞。1年、2年和4年后的原发性通畅率分别为87%、83%和78%；1年、2年和4年后的继发性通畅率分别为94%、90%和88%。
原发性支架置入术应是单侧慢性髂动脉闭塞的首选治疗方法。
