title: Infected femoral artery false aneurysms in drug addicts: evolution of selective vascular reconstruction.
abstract: Fifty-four infected femoral artery false aneurysms resulting from chronic drug addiction were managed surgically with an 11% amputation rate and no mortality. Angiography localized the arterial segment involved, which in turn influenced the type of operation performed. Twenty-six aneurysms of anatomically isolated femoral artery segments were ligated and excised without resultant amputation. However, of the 28 aneurysms involving the common femoral bifurcation, 18 required triple ligation and excision that led to six amputations. Six of the 28 aneurysms were reconstructed with autogenous saphenous vein grafts, three by prosthetic grafts, and one by primary anastomosis. No amputations followed vascular reconstruction. However, all synthetic grafts eventually developed septic complications that required graft removal. On the basis of this experience we recommend ligation and excision for single artery segment aneurysms and immediate autogenous reconstruction for selected common femoral bifurcation lesions. This approach has proved safe and has reduced our amputation and graft complication rates. Extensive uncontrollable wound sepsis may contraindicate revascularization. Under these circumstances we estimate a 33% risk of amputation when the common femoral bifurcation is excised.
