导引导管引起的冠状动脉夹层是冠状动脉成形术的一种罕见但严重的并发症。治疗可包括对受影响血管进行紧急冠状动脉旁路移植术或经皮介入治疗，包括对真腔进行布线和对夹层皮瓣进行排除支架植入，以防止进一步扩散。已经发表了关于有意将导丝插入假腔和在慢性完全闭塞的情况下再次进入真腔的技术的详细描述。我们提出了一个罕见的情况下，似乎是成功的故意假腔支架植入术的医源性夹层的右冠状动脉与TIMI III冠状动脉血流恢复，一年后，并发症的真腔再通和闭塞的支架假腔引起症状性心绞痛的真腔。
Guide catheter induced dissection of coronary arteries is an uncommon, but serious complication of coronary angioplasty. Treatment can include emergent coronary artery bypass grafting to the affected vessel or percutaneous intervention including wiring the true lumen and exclusion stenting of the dissection flap to prevent further propagation. Detailed descriptions have been published of techniques of intentional passage of guide wires into the false lumen and reentry into the true lumen with chronic total occlusions. We present an unusual case of what appeared to be successful intentional false lumen stenting with reentry into the true lumen of an iatrogenic dissection of the right coronary artery with restoration of TIMI III coronary flow which, one year later, was complicated by recanalization of the true lumen and occlusion of the stented false lumen causing symptomatic angina.
