[Surgical anatomy of the posterior tibial veins].

An investigation of the posterior tibial vascular plexus has established certain specific features of its structure both in normality and in patients with postthrombotic disease. The alterations found require an individual approach to choice of surgical measures which is finally determined intraoperatively. At the present time surgical interventions on the posterior tibial veins in patients with postthrombotic disease are thought to be of three types: extended resection, extravasal correction and plasty of the posterior tibial veins.

[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.
