Effect of ethyloestrenol on fibrinolysis in the vessel wall.

64 patients, including 49 with decreased fibrinolytic activity in the vessel walls or a decreased release mechanism (45 with recurrent deep venous thrombosis, 4 with arterial thrombosis) and 15 with a normal fibrinolytic system (4 with recurrent DVT, 11 with severe arteriosclerosis).

Ethyloestrenol 8 mg/day or 4 mg/day for 3 to 17 months.

Spontaneous fibrinolytic activity, local fibrinolytic activity during standardised venous occlusion of the arms, and fibrinolytic activity of the vessel walls.surrogate
