Sclerotherapy for varicose veins of the lower legs in patients with dysplasminogenemia.
Sclerotherapy combined with ligation has become a widely accepted treatment for varicose veins; however, it is associated with some risk of the serious complications of deep vein thrombosis (DVT). We investigated the incidence of thrombophilia in 164 consecutive patients undergoing treatment for varicose veins and determined the activities of antithrombin-III, protein C, and plasminogen. Of the 164 patients, 10 were diagnosed as having dysplasminogenemia (DPG), showing an incidence of 6.1%, in accordance with previous reports. DVT was not found to be caused by DPG in any patient, and no difference was found between patients with and those without DPG, suggesting that DPG is not a risk factor for varicose veins. We also investigated the activation of coagulation by measuring the thrombin-antithrombin III complex (TAT). The activation of coagulation after sclerotherapy was inhibited when ligation was performed 1 month prior to sclerotherapy, whereas it was increased when sclerotherapy and ligation were performed simultaneously. Of the 10 patients with DPG, 5 were treated uneventfully, and their TAT level increased to 4.0 micrograms/l, which was comparable to the level after sclerotherapy and ligation. These findings indicate that sclerotherapy can be performed safely in the majority of patients with DPG, and that the temporal separation of sclerotherapy and surgery is an alternative for these patients to prevent the activation of coagulation.
