[Surgical treatment of non-traumatic aneurysm in ilio-femoral arterial region].

Objective To summarize the surgical experiences of treating 61 cases of non-traumatic aneurysms in ilio-femoral arterial region.Methods The clinical data of 61 consecutive patients with nontraumatic aneurysms in ilio-femoral arterial region between January 1985 and November 2010 were retrospectively reviewed.Results There were a total of 76 non-traumatic aneurysms in ilio-femoral arterial region,including solitary iliac aneurysms ( n =29) and femoral aneurysms ( n =32).Seventeen (27.9％)patients had multiple aneurysms,8 ( 13.1％ ) patients ruptured aneurysms and 4 ( 6.6％ ) patients coexistent peripheral vascular occlusive disease.Fifty patients underwent electively aneurysm excision and graft (or autogenous vein ) replacement.Seven patients with ruptured aneurysms received emergency treatment.And one with multiple aneurysms died intra-operatively from ruptured iliac aneurysm.One patient with common iliac aneurysm underwent endovascular repair without endoleak and 1 with intemal iliac aneurysm received embolization.There was no perioperative mortality.But one with femoral aneurysm underwent amputation due to acute thrombosis.Seven patients died during the follow-up period and the survivors remained stable and had a good graft patency without new aneurysm formation.Conclusion Early management of aneurysms in ilio-femoral arterial region is rather important and multiple aneurysms should be considered.Aneurysm excision and arterial reconstruction yield an excellent outcome.Close and long-term follow-up is mandatory for the detection of new aneurysm formation.
