[Acute thrombophlebitis in the territory of saphena magna vein].

Problems of strategy and policy of surgical treatment of acute thrombophlebitis in the territory of saphena magna vein are discussed. Results of urgent radical combined venectomy in 76 patients are presented. A gas technique of subfascial dissection of perforant veins (SEPS) was used in 52 patients for the first time both for diagnosis and adequate treatment of thrombosed perforants. Spread of thrombosis from superficial veins to perforants was revealed in 14.3% patients with C3-C5 class of venous dysfunction (CEAP classification). Isolated and local forms of crus varicothrombophlebitis that must be urgently operated are distinguished. The mean hospital stay was 8.7 bed-days.
