微创小切口心脏瓣膜手术134例

目的总结经微创小切口行心脏瓣膜手术的临床经验,探讨手术径路、方法、效果以及可能的危险因素。方法采用微创小切口行心脏瓣膜手术134例,其中经胸骨旁切口行主动脉瓣置换术5例,二尖瓣置换术2例;经右胸前外侧切口行二尖瓣手术46例,单纯三尖瓣手术15例;经胸骨上段小切口(反Z字形)行主动脉瓣置换术11例;经胸骨下段劈开加横断右半胸骨(倒L形)切口行二尖瓣手术55例。结果术后早期死亡3例,其中2例死于低心排血量综合征和右心功能不全,1例死于急性肝、肾功能衰竭。随访114例,随访时间2个月~7年,术后6个月患者的心功能均有不同程度的改善,切口疤痕隐蔽,复查心脏彩色超声心动图显示心瓣膜功能良好。结论微创小切口行心脏瓣膜手术可行,避免了完全劈开胸骨,维持胸廓的完整性,减少损伤,相对美观,有利于患者术后的恢复。

Minimally Invasive Cardiac Valve Surgery: Report of 134 Cases

Objective To summarize the clinical experience of cardiac valve surgery with minimally invasive procedure. Methods Cardiac valve surgery with less invasive techniques were performed in 134 cases. Five aortic valve operations and 2 mitral valve operations were performed through para-sternotomy. Forty-six mitral valve operations and 15 tricuspid valve operations were performed through right anterolateral thoracotomy. Eleven aortic valve operations were performed through limited reversed Z sternotomy. Fifty-five mitral valve operations were performed through limited lower sternotomy. Results Three cases died postoperatively, the mortality was 2.2%, 2 patients died of low cardiac output syndrome, and one died of acute hepatic and renal failure. One hundred and fourteen patients were followed-up from 2 months to 7 years. The follow-up results were excellently. The scar of minimally invasive valve surgery was limited. Conclusion Minimally invasive valve surgery can accelerate recovery, while maintaining overall surgical efficacy. The advantages include a better cosmetic scar, less surgical trauma, minimal respiratory discomfort and a potentially lower risk of infection. It is extremely effective and has become our current technique of choice in every mitral and aortic valve patient.
