Abstract

An inadvertent vent in the right ventricle (RV) resulted during dissection of a deep intramyocardial left anterior descending coronary artery (LAD), during off-pump coronary artery bypass grafting (OPCAB), led to pulmonary artery air embolism and hemodynamic instability, requiring conversion to cardiopulmonary bypass (CPB) prior to repair. This required a special maneuver in positioning the patient to identify the RV injury and prevent the pulmonary air embolism.

摘要

在非体外循环冠状动脉旁路移植术(OPCAB)中,解剖左前降支深部心肌内冠状动脉时,无意中造成右心室(RV)出现一个裂口,导致肺动脉空气栓塞和血流动力学不稳定,需要在修复前转为心肺旁路(CPB)。这需要患者采取特殊的体位来识别 RV 损伤并防止肺空气栓塞。
