Composite femoro-tibial bypass as alternative solution in complicated revascolarization: Case report

Peripheral Arterial Disease (PAD) in diabetic patients is a significant cause of Morbility. Long arterial occlusion in patient previously treated can require unusual and complex solution. Herein we report a case of complicated bypass in diabetic patient with history of bypass for bilateral popliteal aneurysm.

A 51-year-old male, smoker, with hypertension and diabetes mellitus was referred to our hospital for rest pain in left limb and peripheral cyanosis. Ultrasound doppler (US) showed an occlusion after common femoral artery with patency of Anterior-tibial artery (ATA) two centimeters after the origin. The unavailability of adequate autologous conduit necessitated an alternative solution and was chosen a composite femoro-anterior tibial artery bypass with successive ATA angioplasty to ensure the patency of graft.

The autogenous vein is the preferred conduit in below-knee vascular reconstructions but in redo-procedures in the absence of vein, synthetic or biologic vascular prostheses must be considered as graft material. In these cases tibial angioplasty can improve the outflow and the patency.

Composite Femoro-ATA bypass with tibial angioplasty is an alternative technique for critically ischemic legs with limited autologous vein material. In our experience this approach was safe and effective.
