Endovascular treatment of iliac aneurysms with covered stents.
The purpose of this retrospective, single-institution study was to analyze the results of endovascular treatment of iliac aneurysm using covered stents. Since January 1, 1996, a total of 34 iliac aneurysms have been treated with covered endovascular stents. The series included 9 isolated aneurysms, 29 aneurysms following repair of aortic aneurysm, and 3 false anastomotic aneurysms. The mean diameter of aneurysm was 42 mm (range, 21 to 120 mm). The aneurysm was either symptomatic or complicated in 11 cases. Three procedures were carried out under emergency conditions after acute rupture. Stent deployment was successful in 33 cases (technical success rate, 97.6%). Exclusion of the aneurysm was obtained in all cases with one (n = 26) or two overlapping (n = 7) covered stents. Mean procedure duration was 45 min (range, 25 to 75 min). The internal iliac artery was patent in 28 cases, but patency was preserved in only 4 cases. In the remaining 24 cases the internal iliac artery was excluded either preoperatively by embolization using Gianturco coils (n = 15) or intraoperatively by placement of the stent (n = 9). Endovascular treatment of iliac aneurysm with covered stents achieves good short- and middle-term results but usually requires exclusion of the internal iliac artery.
