一名40岁男性因高松动脉炎的症状性肺狭窄入院。计算机断层肺血管造影显示左肺无血流，右肺动脉主干严重狭窄（图1）。肺血管造影显示右肺灌注减少（图2A）。尝试在右肺动脉进行球囊肺血管成形术（BPA），但由于患者在球囊扩张期间癫痫发作，BPA停止。我们怀疑癫痫发作是由于球囊扩张时脑内短暂性血流量不足引起的，球囊扩张阻塞了连接右心和肺的唯一肺动脉。在球囊血管成形术中，为了维持肺血流，一个6英尺长的引入鞘被推进到右肺动脉，并成功地穿过病变输送血液。
A40-year-old man was admitted with symptomatic pulmonary stenosis in Takayasu arteritis. Computed tomographic pulmonary angiography demonstrated no blood flow in the left lung and a severe narrowing in the right main pulmonary artery (Figure 1). Pulmonary angiography showed reduced perfusion in the right lung (Figure 2A). Balloon pulmonary angioplasty (BPA) was attempted in the right pulmonary artery, butBPA was ceased because the patient had a seizure during balloon dilation. We suspect that the seizure was triggered by transient loss of blood flow in the brain during balloon dilation, which blocked the only pulmonary artery that connected the right heart and the lungs. To maintain pulmonary blood flow during balloon angioplasty, a 6-F long introducer sheath was advanced to the right pulmonary artery and successfully crossed the lesion to deliver blood,
