[Thromboembolic complications after aortic valve prosthesis].

The presented analysis covers the results of aortic valve replacement in 155 patients followed-up for 1 to 11 years after surgery. Actuarial statistics permitted to reveal the dynamics of survival and of good results of different institutions. No anticoagulation whatsoever was given to 85 patients, while 70 others received Phenylin, 30-60 mg/day. Thromboembolism was found to be the leading complication affecting the survival rate and the stability of good results in the late postoperative period. Among the patients receiving no anticoagulants the incidence of thromboembolism proved significantly higher than among those treated with Phenylin.
