Aneurysmal Degeneration of Deep Lower Extremity Vein Conduits Used for Vascular Reconstruction

Abstract

Background: Successful outcomes have been reported with the use of femoropopliteal vein (FPV) grafts as arterial conduits. We identified 2 patients with a rare complication, true, nonanastomotic aneurysmal degeneration. Methods: Patients from 1997 through 2009 that utilized FPV grafts for revascularization were analyzed. We contacted survivors by phone and conducted a literature search of FPV aneurysms. Results: Of the total of 14 patients in our practice whose FPV was used as a conduit during the study period, 2 developed nonanastomotic FPV graft aneurysms. The mean follow-up time was 33.44 months. Literature review uncovered only 1 previously published case of FPV aneurysmal degeneration. Conclusions: Our experience suggests that nonanastomotic aneurysms of FPV grafts may occur more often than those suspected previously. Our study represents the first reports of aneurysmal degeneration affecting FPV grafts when used for vascular reconstructions.

Aneurysmal degeneration and rupture of deep vein conduit with formation of an arterial-vaginal fistula 13 years after creation of a femoral-femoral bypass

“… 4 Known complications of autologous deep vein grafts include stenosis, thrombosis, compartment syndrome, and venous stasis of the donor extremity; however, aneurysmal degeneration of the deep vein graft is rarely described. 4 , 5 We report the case of an aneurysmal autologous deep vein femorofemoral bypass graft that subsequently ruptured into the vagina of an 87-year-old woman 13 years after the initial procedure. Consent for publication of this case report was obtained from the patient's next of kin.…”
