Endovascular Treatment of Iliac Aneurysms: Short-term results of a new Branched Iliac Stentgraft

which regressed spontaneously in six months in two cases (66%). Buttock claudication was permanent in one case (38%). We did not find a relation between the buttock claudication and the patency of the contralateral hypogastric artery or the deep femoral artery. No endoleak was observed. The aneurysmal sac decreased in diameter in five cases (25%), it was stable in 75% of the patients. The mean duration of hospitalization was four days. The survival rate was 95% at six months and 70% at five years. Half of the deaths were secondary to cardiovascular causes. No late aneurysm ruptures were observed. Conclusion: Embolization of the internal iliac artery to treat an aneurysm is reliable. Hypogastric embolization involves a significant risk of permanent buttock claudication in more than one third of the cases. Bifurcated stentgrafts should contribute to avoid this complication.
