Tonsillectomy was performed on a 47-year-old female whose aortic valve had been replaced with a prosthetic valve 2 years before. In this patient, anticoagulants, sodium warfarin and persantin, had been used to prevent post-valve replacement thromboembolism.Special care had to be taken to reduce bleeding during and after tonsillectomy as well as to minimize thromboembolism. The anticoagulants were discontinued for 2 days preoperatively, and vitamin K was used perioperatively to resume normal coagulability. Exact ligature of the tonsillar arteries was performed at the time of tonsillectomy. Heparin, whose action could be easily controlled at the time of the bleeding, was given for 10 days postoperatively. The patient was discharged uneventfully 17 days after tonsillectomy without any bleeding or thromboembolism.
