Endovascular treatment of aneurysmal deterioration in peripheral arterial allografts.

Purpose: To report endovascular treatment of 2 patients with aneurysmal deterioration of peripheral arterial allografts.
Case Report: Two men (65 and 64 years old) who had undergone an arterial allograft reconstruction for infection of prosthetic infrapopliteal bypass grafts 5 and 7 years ago, respectively, were diagnosed with asymptomatic aneurysmal deterioration of the allografts. Stent-graft repair was successful in both cases, completely excluding the aneurysms. At >or=1 year, continued aneurysm exclusion was confirmed by duplex scan, with no evidence of endoleak, migration, or stenosis.
Conclusion: Endovascular treatment may be a useful therapeutic option when treating patients with late peripheral allograft deterioration.
