Stent migration from the delivery balloon catheter is a rare but serious complication during percutaneous coronary intervention, particularly when a part of the stent stretches into the aorta. We report an unusual case of stent migration treated with a combination of a gooseneck snare and rotablation. A part of the stent was overstretched and unrolled into the aorta and the rest of the stent remained implanted in the coronary artery. The stent was captured with a gooseneck snare but could not be retrieved because it was connected to a stent remnant implanted in the coronary artery. The stent strut was cut with rotablation, and the stent was successfully removed through the femoral sheath.
支架从输送球囊导管迁移是经皮冠状动脉介入治疗中一种罕见但严重的并发症，尤其是当支架的一部分延伸到主动脉时。我们报告了一例使用鹅颈套圈和旋磨术联合治疗的支架迁移的不寻常病例。一部分支架过度拉伸并展开到主动脉，而其余的支架仍植入在冠状动脉中。支架被鹅颈套圈捕获，但由于与植入冠状动脉中的支架残端相连，无法取出。支架支柱用旋磨切割，支架通过股动脉鞘成功取出。
