Preoperative hemodynamics in the lower limbs in 174 limbs of 103 patients were measured and investigated and the surgical results were evaluated. The subjects were divided into the C<sub>4-6</sub>-group, which included 51 limbs with skin changes, and the C<sub>2, 3</sub>-group, which consisted of 123 limbs without skin changes. Plethysmography showed that the maximum venous outflow was significantly higher, and the refilling time was shorter in the C<sub>4-6</sub>-group compared to the C<sub>2, 3</sub>-group. All C<sub>4-6</sub>-group patients had reflux of the long saphenous vein, and the reflux velocity and volume was significantly greater than in the C<sub>2, 3</sub>-group. Limbs with deep vein reflux accounted for 45% of the C<sub>4-6</sub>-group. We performed angioscopic deep vein external valvuloplasty in 23 of those limbs. There was no case of reccurence of skin changes at a mean follow-up of 22 months. However chronic venous insufficiency often was associated with multisegmental reflux lesions and in such cases it might be necessary to perform multiple surgical procedures to eliminate the reflux.

To investigate the effect of nafamostat mesilate (FUT) for disseminated intravascular coagulation (DIC) after surgery using cardiopulmonary bypass, we studied DIC scores and parameters of coagulation and fibrinolysis in the DIC cases. Although 12 patients developed DIC, the platelet counts improved by administration of FUT apart from one complicated by sepsis. The DIC scores decreased as a result of the increase of platelets and fibrinogen and improvement of FDP. Thrombin-antithrombin III complex, D-dimer and plasmin-α<sub>2</sub> plasmin inhibitor complex showed an even higher value at the endpoint of FUT administration. These results indicate that patients with DIC after cardiopulmonary bypass may have severe fibrinolytic acceleration and that administration of FUT can be useful in those cases.
