Fourteen patients underwent thrombectomy for thrombosis of implanted Björk-Shiley valves (13 in the mitral and one in the aortic position) between January, 1975, and July, 1984. There was no operative mortality or perioperative embolism. Over a follow-up period of 1 to 96 months (average 23.5 months), there was no late mortality. Serial evaluation of valve function by cinefluoroscopy and echocardiography has shown no evidence of rethrombosis or valve dysfunction in any of the patients. Cardiac catheterization and angiocardiography done in 10 patients at various intervals (1 month to 6 years) postoperatively have shown normal valve function in all and normalization of elevated preoperative intracardiac pressures in the majority. Our experience suggests that thrombectomy of thrombosed Björk-Shiley valves provides excellent early and long-term results in terms of patient survival and valve function.
1975年1月至1984年7月期间，14例患者因植入的 Björk-Shiley 瓣膜血栓形成接受了血栓切除术（二尖瓣位置13例，主动脉位置1例）。无手术死亡或围手术期栓塞发生。在1至96个月（平均23.5个月）的随访期内，无晚期死亡。通过荧光电影摄影术和超声心动图对瓣膜功能进行的系列评估显示，所有患者均无再血栓形成或瓣膜功能障碍的证据。10例患者在术后不同时间间隔（1个月至6年）进行了心导管检查和心血管造影，结果显示所有患者瓣膜功能正常，大多数患者术前升高的心内压恢复正常。我们的经验表明，就患者生存和瓣膜功能而言，对血栓形成的 Björk-Shiley 瓣膜进行血栓切除术可提供优异的早期和长期效果。
