Isolated iliac artery aneurysms: endovascular versus open elective repair.

Abstract：

OBJECTIVE:To compare endovascular and open repair of isolated or solitary iliac artery aneurysms (SIAAs). METHODS:We present the results of 55 patients with 58 SIAAs that were treated between January 1998 and December 2005 in two European university hospitals. In one center, the standard procedure, if not contraindicated, was endovascular repair, and 32 (58.2%) consecutive patients with 33 SIAAs were treated by using only endovascular techniques (endovascular iliac aneurysm repair; EVIAR). In the second center, 23 (41.8%) consecutive patients with 25 SIAAs were treated by conventional surgical techniques because advanced endovascular skills were not available before late 2005. EVIAR included coil embolization of the hypogastric artery in 13 of the 33 cases with aneurysmal involvement of the internal iliac artery. In the "open" group of patients, midline laparotomy and a transperitoneal approach with bifurcated aortoiliac graft replacement was performed in 4 cases, and a lower lateral abdominal incision with a retroperitoneal approach and iliac replacement was performed in 19 cases. RESULTS:The mean follow-up period was similar in both groups (EVIAR, 35.3 +/- 21.3 months; open, 31.3 +/- 19.9 months). The two groups of patients had similar demographic and clinical characteristics compared with previous reported series, and data analysis revealed a statistically significant difference between the two groups only in hypertension. The early and mid-term outcomes and especially the 3-year primary patency rates were also similar between the two groups (EVIAR, 97%; open, 100%). In the EVIAR group, there was no evidence of endoleaks, kinking, or graft migration, and 26 aneurysms remained stable, whereas in 7 aneurysms a slight decrease in size (>10% in diameter) was observed. Comparison of operative time, intraoperative blood loss, and postoperative hospital stay revealed significant differences (P < .001) in favor of the endovascular group. Secondary intervention was not necessary in any patient in either group during the entire follow-up period. CONCLUSIONS:Elective management with endovascular or open techniques of isolated iliac aneurysms can be accomplished with very low morbidity and mortality rates. Better intraoperative and early postoperative outcomes, as well as the durable mid-term results in our EVIAR-treated patients, indicate that endovascular techniques could be offered as first-line therapy of SIAAs.
