[A present-day approach to surgery for the formation of crossed femoro-femoral shunts in unilateral occlusions of the ilio-femoral venous segment (indications, principles of the surgical technique)].

As distinct from the classical Palme-D'Esperon operation in which the anastomosis is established with the common femoral vein, the authors prefer to form the anastomosis in the region of the saphenofemoral communication in inadequate drainage in the iliofemoral segment in patients with the postthrombotic disease. Seven variants of crossed femorofemoral shunting (CFFS) were carried out. The anastomoses were formed by means of precision techniques; an operating microscope was used when the anastomosis measured less than 5 mm in diameter. The CFFS was found to be patent in follow-up periods of up to 2.5 years in all cases. From analysis of the late-term results of CFFS, the authors claim that functional block of venous drainage from the femoro-iliac segment, rather than anatomical occlusion, is the indication for this operation.
