Balloon pulmonary angioplasty (BPA) has been recognized as an alternative therapeutic approach for patients with inoperative chronic thromboembolic pulmonary hypertension and those with residual pulmonary hypertension after pulmonary endarterectomy. However, the safe and successful treatment rate for a total occlusion lesion (TOL) using BPA is low, mainly because vessels distal to the occlusion are invisible by angiogram. Here, we present the case of a 53-year-old woman with chronic thromboembolic pulmonary hypertension with successfully recanalization of a TOL by use of BPA with the aid of intracardiac echocardiography. The intracardiac echocardiography-assisted wire passage technique may be a promising method for safe and reliable TOL treatment using BPA.
球囊肺动脉血管成形术(BPA)已被公认为是无法进行手术的慢性血栓栓塞性肺动脉高压患者以及肺动脉内膜剥脱术后残留肺动脉高压患者的一种替代治疗方法。然而,使用BPA治疗完全闭塞病变(TOL)的安全成功率较低,主要原因是血管造影无法显示闭塞远端的血管。在此,我们报告一例53岁患有慢性血栓栓塞性肺动脉高压的女性患者,通过心腔内超声心动图辅助,成功使用BPA使TOL再通。心腔内超声心动图辅助导丝通过技术可能是一种使用BPA安全可靠治疗TOL的有前景的方法。
