Partial anomalous pulmonary venous return: iatrogenic occlusion of the innominate vein producing right-to-left shunt.

摘要

A patient experienced acute dyspnea and hypoxia upon removal of a thrombosed peripherally inserted central venous catheter. This was shown to be caused by innominate vein occlusion complicated by a right-to-left shunt, via an anomalous pulmonary vein, causing arterial desaturation. A stent was placed in the occluded innominate vein and arterial saturation returned to normal.
