目的总结自体肺动脉瓣移植术(Ross手术)围术期治疗的经验。方法我院1994年10月—2009年2月共收治了58例中重度主动脉瓣病变行Ross手术者,其中男42例,女16例;平均年龄(28±15)岁。术前诊断:先天性心脏病,主动脉瓣中重度狭窄和(或)关闭不全54例;亚急性细菌性心内膜炎(SBE)合并主动脉瓣关闭不全1例;主动脉瓣人工机械瓣置换术后心内膜炎合并瓣周漏1例;主动脉瓣成形术后主动脉瓣大量反流1例;老年性退行性重度主动脉瓣狭窄1例。患者术前均行超声心动图(UCG)检查。术前准备:NYHA心功能分级Ⅰ、Ⅱ级患者术前按心脏手术常规准备,心功能Ⅲ级患者术前给予洋地黄、利尿剂、极化液治疗,待心功能改善后再行手术。手术方式:患者均在全麻中度低温体外循环下接受Ross手术,手术顺利。围术期监护治疗措施:严密监测生命体征,积极补充血容量,维持水、电解质和酸碱平衡,预防并有效处理心律失常的发生,维护心功能,加强抗炎治疗。结果58例患者术后死亡1例(1.7%),自动出院1例;术后主动脉瓣平均跨瓣压差为(6.11±0.12)mmHg,显著低于术前的(35.56±9.10)mmHg;左室舒张末期内径(LVDD)为(56±3)mm,亦显著低于术前的(62±5)mm,差异均有统计学意义(P〈0.01)。左室射血分数为(0.49±0.22)%,心功能均为Ⅰ~Ⅱ级。结论Ross手术是治疗主动脉瓣病变的有效方法,良好的围术期治疗为手术的成功提供了有力帮助。
Objective To summarize the experience on peri-operative treatment in patients receiving pulmonary valve autograft (Ross Procedure).Methods Fifty-eight patients with severe aortic valve lesions,admitted to our hospital from October 1994 to Februry 2009,42 males,16 females,averaging in age of 28±15,received Ross procedure.According to pre-operative diagnoses,congenital heart disease (CHD),aortic valve disease (AS/or AI) were found in 54 patients,subacute bacterial endocarditis (SBE),aortic incompetence in 1,SBE with peri-valve leakage after aortic mechanical valve replacement in 1,aortic incompetence after aortic valve plasty in 1,elderly degenerated aortic valve disease in 1.Ultrasonic cardiogram was performed.Pre-operative preperations were:conventional preperations for heart function NYHA Ⅰ,Ⅱ patients,digitalis,diuretic and polarized solution for NYHA Ⅲ patients,procedure performed after heart function improvement.Patients received procedure under general anesthesia and in moderate hypothermic cardiac-pulmonary bypass (CPB).Vital sign was closely monitored,blood volume added positively,water,electrolyte and acid-base balance maintained,arrhythmias prevented and effectively dealt,heart function maintained and anti-inflammatory treatment enhanced.Results One patients died after procedure (1.7%),1 auto-discharged.The average pressure difference of aortic valve was 6.11±0.12 mm Hg,significantly lower than before procedure (35.56±9.10 mm Hg),and left ventricular diastolic diameter (LVDD) was 56±3 mm,lower than before procedure (62±5 mm),the difference was significant (P0.01).Left ventricular ejection fraction was (0.49±0.22)%,heart function were between grades Ⅰ~Ⅱ.Conclusion Ross procedure is an effective method in treatment of aortic valve lesions.Good peri-operative treatment provides a powerful help for a successful operation.
