左向右分流型先天性心脏病的重要合并症是肺动脉高压,而肺动脉高压增加了手术的危险性并影响治疗效果。放大的肺小动脉楔状造影从影象学角度为临床提供了对肺血管床的直接认识,为判断手术时机提供了依据。我们采用气囊漂浮导管对30例左向右分流先天性心脏病行放大肺小动脉楔状造影,现报告如下。 Pulmonary hypertension is an important complication of left-to-right shunt congenital heart disease, and pulmonary hypertension increases the risk of surgery and affects treatment outcomes. Enlargement of pulmonary arterioles wedge angiography provides a direct understanding of the pulmonary vascular bed for clinical imaging from the perspective of imaging, to provide a basis for determining the timing of surgery. We use balloon floating catheter for left to right shunt in 30 cases of congenital heart disease enlarge pulmonary arteriole wedge, are as follows.
