Dysfunction of a mechanical prosthetic valve caused by thrombus formation is usually treated surgically. A patient with a thrombosed Björk-Shiley valve in the aortic position was treated successfully with intravenous streptokinase. The considerable improvement in the patient's clinical condition and the phonocardiographic, echocardiographic, and cinefluoroscopic evidence of normalisation of prosthetic valve function established the efficacy of thrombolytic therapy of a thrombosed prosthetic valve in this patient.
机械人工瓣膜因血栓形成导致功能障碍通常采用手术治疗。一名主动脉位置的Björk-Shiley瓣膜形成血栓的患者经静脉注射链激酶成功治愈。患者临床状况的显著改善以及人工瓣膜功能恢复正常的心音图、超声心动图和荧光电影造影证据证实了该患者血栓形成的人工瓣膜溶栓治疗的有效性。
