Described is an unusual complication occurring during right-sided cardiac catheterization using a 7F flow-directed balloon catheter. During an attempt to direct the catheter from the main pulmonary artery into the pulmonary wedge position, the tip became entangled in a loop of catheter and knotted. Initially, all attempts to unknot or remove the catheter failed. A movable core guide wire was passed through the major lumen of the catheter, resulting in the immediate unknotting of the catheter, thus allowing its withdrawal.
描述了一种在使用7F血流导向球囊导管进行右侧心导管插入术期间发生的罕见并发症。在试图将导管从主肺动脉引导至肺楔压位置时，导管尖端缠结在一段导管中并打结。最初，所有解开或取出导管的尝试均失败。一根可移动的导丝穿过导管的主要腔道，导管随即解开，从而得以撤出。
