目的通过改良Robicsek法胸骨固定及双侧胸大肌内侧头转移在非体外循环冠状动脉旁路移植术（OPCAB）患者胸骨固定中的应用，探讨此技术在预防OPCAB术后胸骨并发症的作用。 方法回顾性分析2011年2月至2013年4月北京安贞医院46例符合高危人群指征的心脏病患者行改良Robicsek法胸骨固定及双侧胸大肌内侧头转移手术的临床资料。男17例，女29例；年龄63～82（68.6±4.6）岁。 结果46例患者手术过程顺利，无1例发生胸骨并发症。1例死于围手术期心肌梗死、左心力衰竭，其余患者术后肌瓣存活良好。45例术后14 d拆线，伤口愈合良好。所有患者出院后1个月、6个月进行随访，皮肤切口愈合良好，胸骨固定良好，无窦道形成，未见反常呼吸运动，胸廓外形良好。 结论相对于传统闭合切口的方法，对可能发生胸骨合并症的高危人群，采用改良Robicsek法胸骨固定及双侧胸大肌内侧头转移术有一定的优势，能降低胸骨裂开及切口感染的概率，从而降低全身感染的概率，缩短患者康复时间，减轻心理压力。
ObjectiveTo explore the incidence of total occlusion of right coronary artery (RCA)and its treatment strategy during off-pump coronary artery bypass grafting (OPCAB). MethodsA total of 1 153 patients with total RCA occlusion were chosen from 6 206 patients who underwent OPCAB in Beijing Anzhen Hospital from January 1, 2005 to December 31, 2012. There were 889 male (77.1%)and 264 female (22.9%)patients with their age of 45-78 years. The incidence of total RCA occlusion was calculated, and its treatment strategies were discussed. ResultsAmong 6 206 OPCAB patients, 1 153 patients (18.6%)had total RCA occlusion. All the 1 153 patients successfully received OPCAB, but 13 patients (1.1%)died postoperatively. Thirty-four patients (2.9%)had postoperative complications including cerebral infarction, mild to moderate pleural effusion and poor wound healing, all of whom were cured or improved, and all the other patients were discharged uneventfully. A total of 1 110 patients (97.4%)were followed up for 1 month to 7 years, and 30 patients were lost during follow-up. Angina symptoms disappeared in 758 patients and were relieved in 352 patients. During follow-up, 64-row helical CT of 586 patients with preoperative total RCA occlusion showed good graft patency, and echocardiography and nuclear myocardial scan showed improved left ventricular systolic function and myocardial blood flow. ConclusionThe incidence of total RCA occlusion is 18.6% in our study. Appropriate surgical strategies are needed according to individualized patient conditions to get satisfactory clinical outcomes.
