ABSTRACT
Objective To study the effective surgical methods for the sequela of deep vein thrombosis(DVT) of lower extremity . Methods The clinical data of 32 patients with the sequela of DVT of lower extremity in 36 limbs treated by surgery since 1992 were analysed retrospectively. Results Diagnosis accuracy rate of angiography in sequela of DVT was 100%. There were type I in 5 limbs, type IIA in 4, type IIB in 12,and type III in 15. External constriction valvuloplasty of superficial fomoral vein(SFV) was performed on 16 limbs,valvuloplaasly of SFV on 3 limbs,great saphenous vein popliteal vein anastomosis in situ in 6 limbs,muscular loop plasty on popliteal vein in 4 limbs,common iliac vein SFV anastomosis with artificial vessel interposition in 3 limbs,great saphenoas vien ansatomosed to opposite SFV in 4 limbs. After treatment,symptoms totally disappeared in 28 limbs ( 77.8% ), and improved in 8 limbs. Conclusions The vasography is diagnostic chrysindicatrix of the DVT sequela. Different operations based on the damage of valves should be chosen.
