[Results of endoprostheses in the iliac arteries; an experience apropos of 47 implantations].
Obstruction or stenosis of the iliac artery was treated by placement of an endoprothesis in 41 patients. A total of 47 lesions was treated. 26 patients had poor results of balloon angioplasty including residual stenosis (7 cases), restenosis post angioplasty (7 cases), and dissection (12 cases). 15 patients had iliac occlusion. The endoprothesis used was a self expandable flexible endoprothesis (Wallstent) in 26 cases and a balloon expandable flexible endoprothesis (Strecker) in 21 cases. Complications included one thrombosis of the endoprothesis occurred immediately after placement, one hematoma. No distal embolization occurred. Patency at the end of the study was 70% at 9 months and 50% at 21 months. Patency was better with the Wallstent endoprothesis (60% at 21 months) than with the Strecker endoprothesis (38% at 21 months). Results was better with lesions of the common iliac artery, and when the indication was dissection or failure of angioplasty. During the 21 months of follow-up 18 occlusions or restenosis occurred. At the end of the study 20 patients (49%) were asymptomatic and improvement was achieved in 9 (22%), the clinical success rate was 71%. One amputation was required.
