Effect of defibrotide in electrically induced thrombosis in dogs.
Thrombi were electrically induced in dogs. The alterations of the vessel wall were studied in samples obtained on the 8th day from control and treated animals. Changes in coagulation parameters were monitored daily. Animals were treated with 600 mg defibrotide (Crinos) daily for a week, starting 24 h after the induction of thrombi. In the control dogs there was thickening of intima with endothelial hyperplasia and smooth muscle proliferation. The treated animals did not show any morphological or ultrastructural alterations (SEM). This observation encourages us to examine the role of fibrinolytic and endothelial supportive therapy for prevention of development of vascular changes.
