Abstract

Thrombosis in valve or left atrium after mechanical mitral valve replacement causes prosthetic valve dysfunction or thromboembolism. Early and adequate therapy is very important but clinically not easy. Thrombolysis can avoid reoperation-related risks and act as an optimal therapy for prosthetic valve thrombosis. This report describes three patients who were treated by using low molecular weight heparin (LMWH) and wafarin. Two patients, including one pregnant woman, had prosthetic valve thrombosis and immobility of valve leaflets, and one patient with recent cerebral infarction due to thromboembolism had thrombus in left atrium. Fraxiparine 0.3 cc (7,500 ICU AXa) was administrated subcutaneously twice or triple daily. At discharge, thrombosis in valve and left atrium were completely or near totally lysed and valve leaflets were normally mobile. During the period of thrombolysis and follow up, there were no complications in all patients.

승모판의 기계판막치환술 후 판막이나 좌심방 내 혈전증은 판막 기능장애나 혈전색전증을 일으킨다. 조기 진단과 적절한 치료는 중요하지만 임상에서 쉽지 않다. 혈전용해 치료는 혈전증으로 인한 재수술의 위험성을 줄일 수 있어 혈전증 치료에 적절한 한 방법이 될 수 있다. 본 보고는 저분자량 헤파린과 와파린으로 혈전용해 치료를 한 3명의 환자를 보고하고자 하였다. 한 명의 임산부를 포함한 2명의 환자는 판막 혈전증으로 인한 판막폐쇄와 개폐운동 장애가 있었고 다른 한 명은 내원 5일전 혈전색전증으로 뇌경색이 발생한 좌심방내 혈전증 환자였다. 환자들은 프락시파린 0.3cc (7,500 ICU AXa)을 하루에 2∼3번씩 피하로 투여하여 치료를 받았다. 퇴원 당시 판막과 좌심방 내 혈전은 완전히 혹은 거의 완전히 용해되었고 판막의 개폐운동은 정상이었다. 혈전용해 때부터 외래 추적 기간동안 특별한 부작용은 없었다.
