Abstract

A distortion of implanted coronary stent along its longitudinal axis during coronary intervention is known as longitudinal stent deformation (LSD). LSD is frequently seen with newer drug eluting stents (DES), specifically with PROMUS Element stent. It is usually caused by impact of guide catheter tip, or following passage of catheters like balloon catheter, IVUS catheter, guideliner, etc. We hereby report a case of LSD during coronary bifurcation lesion intervention, using two-stents technique. Patient had acute stent thrombosis as a complication of LSD, which was successfully managed.

摘要

冠状动脉介入治疗期间植入的冠状动脉支架沿其纵轴发生的扭曲被称为纵向支架变形（LSD）。LSD在新型药物洗脱支架（DES）中经常出现，特别是在PROMUS Element支架中。它通常是由导引导管尖端的撞击引起的，或者是在球囊导管、血管内超声导管、导丝等导管通过之后发生的。我们在此报告一例使用双支架技术进行冠状动脉分叉病变介入治疗期间发生LSD的病例。患者因LSD出现急性支架血栓形成并发症，但已成功处理。
