[Mixed aorta-popliteal by-pass: a new proposal for the treatment of extensive ilio-femoral obstruction].

The nosological polymorphism of peripheral arterial obstruction (A.O.P.) continuously requires new surgical techniques of vascular repair. This led the AA. to develop a new composed aorto-popliteal by-pass. It consists of a proximal (aorto-femoral) synthetic segment (Dacron D.V.) which is distally anastomozed to a biological (Meadox-Dardik Biograft) femoral-popliteal segment. Indications for aorto-popliteal by-pass, technical problems, patient selection and results are here discussed.
