A pulmonary vein angiogram was performed using a pressure injection with the tip of an end and side hole catheter in a near-wedge position; extravasation of contrast material into a bronchus occurred, causing severe bronchoconstriction. It may be possible to avoid this complication by the use of an end hole balloon catheter in the wedge position, slow flow rates of contrast material, and low pressure injections.
使用端侧孔导管尖端在近楔形位置进行压力注射以进行肺静脉血管造影；造影剂外渗至支气管，导致严重支气管痉挛。通过在楔形位置使用端孔球囊导管、缓慢的造影剂流速和低压注射，有可能避免这种并发症。
