[Defibrotide in the prevention of deep venous thrombosis in gynecologic surgery. A controlled study versus calcium heparin in 120 patients]

Abstract

The efficacy of defibrotide and calcium heparin in the prevention of Deep Vein Thrombosis (DVT) in gynecological surgery were compared in a randomized study. Seventy patients candidate to gynecological surgery (for benign conditions) and 50 candidate to surgery for malignancies were randomly allocated either to defibrotide (400 mg b.i.d. IM from the day before operation to the 7th postoperative day, n = 60) or to calcium heparin (5000 IU t.i.d. SC from the operation to the 7th postoperative day, n = 70). The diagnosis of DVT was made with impedance plethysmography and if necessary confirmed with phlebography. No patient developed established DVT in either groups and no adverse reactions were observed. These results indicate that defibrotide may be considered as an alternative to heparin in the DVT prophylaxis in gynecological surgery.
