由于肺动脉导管术引起肺动脉穿孔为少见并发症,在应用尖端带球囊的血流引导导管(经查为Swan-Ganz氏导管,译者)实行术操作中仅占0.125%。其原因为导管尖端直接穿破动脉壁,球囊过度膨胀或偏心性膨胀以及球囊置于动脉分叉部。因该项操作所致的动脉破裂的死亡率高达50%,伴有肺动脉高压或凝血性疾病者则几乎达100%。作者报道了2例因肺动脉导管操作引起的肺动脉假性动脉瘤,用经导管可脱性球囊栓塞治疗成功的经验。2例均为女性,年龄分别为78和68岁,在进行肺动脉导管检查术中突然发生咯血及肺内大片阴影,经保守治疗后,造影证实为肺动脉假性动脉
Pulmonary artery catheterization is a rare complication of pulmonary artery perforation, accounting for only 0.125% of the total volume of the balloon catheter used (Swan-Ganz catheter, translator). The reason is that the catheter tip directly penetrates the arterial wall, the balloon is over-inflated or eccentrically inflated, and the balloon is placed at the arterial bifurcation. The rate of death from arterial rupture due to this procedure is as high as 50%, with almost 100% of those with pulmonary hypertension or coagulopathy. The authors reported two cases of pulmonary artery pseudoaneurysm caused by pulmonary artery catheterization, the successful experience with the treatment of catheter-removable balloon embolization. Two patients were female and were respectively 78 and 68 years old. During the pulmonary catheterization, hemoptysis and massive lung shadow suddenly occurred. After conservative treatment, angiography confirmed pulmonary artery pseudo-artery
