内膜下或假腔支架置入是经皮冠状动脉介入治疗的罕见并发症。大多数球囊引起的小型非血流限制性夹层会自发愈合，如果远端冠状动脉血流不受影响，可以通过密切观察进行医学治疗。然而，复杂和严重的限流术后夹层可能会导致突然的血管关闭和血栓形成，随后的心肌缺血和坏死，可以通过冠状动脉支架术有效治疗。在完全闭塞病变中放置支架前，必须确保导丝位于真腔内，否则支架放置会损害远端冠状动脉血流。我们在这里介绍一个有趣的情况下，成功的冠状动脉再通，尽管假腔支架植入术的近端右冠状动脉后，真腔支架。
Subintimal or false lumen stent deployment is a rare complication of percutaneous coronary interventions. The most balloon-induced small non-flow limiting dissections heal spontaneously and can be treated medically with close observation if distal coronary flow is not compromised. However, the complex and severe flow-limiting postprocedural dissections may result in abrupt vessel closure and thrombosis, with ensuing myocardial ischemia and necrosis, and can be treated effectively by coronary stenting. It is essential to ensure that the guide-wire is in the true lumen before placing the stent in total occlusive lesions, otherwise the stent placement will impair distal coronary flow. We present here an interesting case of successful coronary recanalization despite false lumen stenting of the proximal right coronary artery followed by true lumen stenting.
