We report echocardiographic observations during external chest compression in a patient with marked abnormalities in thoracic anatomy following emergency surgery of aortic arch aneurysm. Transesophageal echocardiography demonstrated direct right ventricular, aortic and left atrial compression, only minimal left ventricular compression and an open mitral valve during closed chest heart massage. Colour flow doppler demonstrated forward blood flow across the mitral valve and along the left ventricular outflow tract during the compression phase. Echocardiographic findings indicate that factors apart from simple cardiac pump mechanism contributed to blood flow during cardiopulmonary resuscitation (CPR) in this postoperative patient after a major thoracic surgical intervention.
我们报告了1例主动脉弓动脉瘤急诊手术后胸廓解剖结构明显异常患者在胸外按压期间的超声心动图观察结果。经食管超声心动图显示，在胸外心脏按压期间，右心室、主动脉和左心房受到直接压迫，左心室仅受到轻微压迫，二尖瓣开放。彩色多普勒血流显像显示在按压阶段有血流穿过二尖瓣并沿左心室流出道向前流动。超声心动图结果表明，在这例接受大型胸外科手术后的患者进行心肺复苏（CPR）期间，除了简单的心脏泵血机制外，其他因素也对血流产生了影响。
