Localization of acute deep venous thrombosis in women taking oral contraceptives.

Abstract

In an investigation of 62 patients from fifteen to forty-five years of age with acute deep venous thrombosis of the lower limb, it was found that the disease had originated most often in the calf veins in men and in women not using oral contraceptives. In women using oral contraceptives, the thrombosis started least often in the calf veins and most often in the iliofemoral veins. A tentative explanation of this difference in localization of thrombosis of the leg with the use of oral contraceptives is given.
