主动脉瓣人工瓣膜置换术156例分析

目的总结成人主动脉瓣人工机械瓣膜置换手术的经验.方法1996年1月至2005年1月对156例成人行主动脉瓣置换,术中均行人工机械瓣膜置换,其中双叶瓣125例,单叶瓣31例.13例行瓣膜侧倾缝合,6例行主动脉瓣瓣环加宽.结果存活151例,死亡7例,死亡率4.48%.结论对主动脉瓣膜行人工机械瓣瓣膜置换手术术前充分估计瓣环大小,术中良好的灌注、心肌保护、选择合适瓣膜和恰当手术方法,可降低死亡率.

Clinical analysis of 156 cases of aortic valve replacement

Objective The aim of this study is to sum up the experience of artificial mechanical aortic valve replacement in adults. Method From Jan.1996 to Jan.2005, 156 mechanical prosthetic aortic valve replacements were performed, one hundred and twenty five double- leaflet valves and 31 single- leaflet valves were employed. Thirteen mechanical prosthetic valves were implanted at an angle of inclination and aortic root enlargement procedures had been performed in 6 patients. Result 151 patients discharged from the hospital in good condition after operations and 7 patients died. The mortality was 4.48%. Conclusion With regard to mechanical prosthetic aortic valve replacement, evaluating the diameters of aortic annulus fully before operation, sufficient myocardial perfusion and protection during operation, and choosing appropriate valve type and operative procedure could reduce the mortality.
