Two cases of cardiac herniation and volvulus that occurred after right pneumonectomy are presented. Both asymptomatic patients demonstrated an unusual bulging contour to the right side of the heart on radiographs obtained in the recovery room, before complete herniation and volvulus occurred. In an autopsy preparation, a similar right contour was produced after partial cardiac herniation through a pericardial defect. The hemispheric contour from partial cardiac herniation resembles the shape of a snow cone. Clinical awareness of this sign of impending herniation is important, so risk factors known to produce herniation may be modified.
本文报告了两例右肺切除术后发生心脏疝和扭转的病例。两名无症状患者在恢复室拍摄的X光片上，在完全疝出和扭转发生之前，心脏右侧均出现了异常的膨出轮廓。在尸检标本中，通过心包缺损部分心脏疝出后也出现了类似的右侧轮廓。部分心脏疝出形成的半球形轮廓类似于圆锥体的形状。临床认识到这种即将发生疝出的征象很重要，这样就可以对已知会导致疝出的危险因素进行调整。
