摘要: Summary A total of 111 survivors prosthetic valve insertion were followed an average 4 years to assess the risk thromboembolism or hemorrhage. Non-cloth-covered ball and/or disc prostheses used, and all patients received long-term anticoagulant therapy. During follow-up period with mitral combined replacement suffered four times more thromboembolic episodes had a poorer survival rate than isolated aortic replacement. The management anticoagulation complications resulting from 44 subeequent noncardiac operations analyzed. Anticoagulation was discontinued before 25 in there no perioperative thromboemboli. Ten performed on cessation prior surgery two deaths due Unanticipated hemorrhage encountered nine whom maintained during surgery. Cessation for 3 5 days appears safe who require subsequent operations. incidence after is high constitutes major whether not operation required.
