A 58-year-old man with severe left lower extremity claudication and rest pain underwent percutaneous transluminal angioplasty. A high-pressure balloon was inflated in an area of severe atherosclerotic narrowing. The patient complained of severe pain during inflation and had a vasovagal response. After balloon deflation, angiography displayed extravasation just inferior to the lower edge of the balloon. Immediate inflation of the balloon tamponaded the leak and allowed the patient's transfer to the operating room in stable condition. It is hypothesized that the new high-pressure balloons can overcome resistance in nondistensible arterial walls, causing rupture without balloon rupture.
一名58岁男性，有严重的左下肢间歇性跛行和静息痛，接受了经皮腔内血管成形术。在严重动脉粥样硬化狭窄区域使用高压球囊进行扩张。球囊扩张时患者主诉剧痛，并出现血管迷走神经反应。球囊放气后，血管造影显示在球囊下缘下方有造影剂外渗。立即再次充盈球囊压迫止血，使患者在病情稳定的情况下被转送至手术室。据推测，新型高压球囊能够克服不可扩张动脉壁的阻力，导致动脉破裂而球囊未破裂。
