Abrupt closure of a dominant right coronary artery occurred in a patient 1 h post coronary angioplasty. Angiography revealed a long spiral dissection involving the mid to distal segment of the right coronary artery. Four intracoronary balloon expandable stents were deployed to 'tack up' the dissection and recanalize the occluded artery. Six month follow-up angiography revealed continued patency of the stented segment. Balloon expandable stents may be an effective alternative to coronary bypass surgery in the treatment of acute closure following coronary angioplasty.
一名患者在冠状动脉血管成形术后1小时发生右冠状动脉优势支突然闭塞。血管造影显示右冠状动脉中至远段有一长段螺旋形夹层。植入了4个冠状动脉内球囊可扩张支架以“固定”夹层并使闭塞的动脉再通。6个月后的随访血管造影显示支架置入段持续保持通畅。在治疗冠状动脉血管成形术后的急性闭塞方面，球囊可扩张支架可能是冠状动脉搭桥手术的一种有效替代方法。
