Why the study?
Do low-dose heparin, heparin combined with dihydroergotamine, or dextran-60 prevent postoperative venous thrombosis and pulmonary embolism in vascular surgical patients?

This study aims to compare three pharmacological prophylaxis strategies for preventing venous thromboembolism in vascular surgery patients.
RCT comparing three VTE prophylaxis regimens in vascular surgery; leaves open optimal postoperative strategy.
Thrombosis prophylaxis is indicated in vascular surgical patients for two general considerations: to prevent thromboembolism from the venous system and occlusion of reconstructed arterial vessels. The purpose of this randomized, prospective study was to compare the effectiveness of low-dose heparin, heparin in combination with dihyder gotamine, and dextran-60 in the prevention of postoperative venous throm bosis and pulmonary embolism after vascular operations. In addition, any adverse effects of each medication on patency after arterial reconstruction was to be determined.
