OBSERVATIONS ON LATE SEQUELAE OF THROMBOSIS OF DEEP VEINS IN LOWER EXTREMITIES
Sun Jianming. et al. Department of Surgery, The Ninth People's Hospital, Shanghai Second Medical College, etc.
Through observations on 36 cases (40 legs) with valvular incompetence as late sequelae of deep vein thrombosis, the authors classified the disease into 3 types, namely, completely obstructed type (type Ⅰ, 11 legs), partially recanalized type (type Ⅱ, 19 legs) and completely recanalized type (type Ⅲ, 10 legs). Type Ⅱ is further subdivided into Ⅱ_A (veins largely obstructed, 11 legs) and Ⅱ_B (veins largely recanalized, 8 legs). In types Ⅰ and Ⅱ_A, non-operative treatment was adopted while waiting for recanalization, but for type Ⅱ_B and Ⅲ patients, bypass or reconstructive operations were considered. In patients with recurrent leg ulcer and without indication to reconstructive operation, stripping of superficial veins with ligation of the communicating branches remained the operation of choice.
