Coronary stent dislodgment is a rare but serious complication during percutaneous coronary intervention. During transradial coronary intervention, retrieval of a dislodged and deformed stent into the guiding catheter is difficult or impossible, since a small 6 Fr guiding catheter and sheath system is commonly used. I describe a new method to retrieve a dislodged and damaged stent during transradial coronary intervention. When a dislodged and unexpanded stent is not pulled back completely into the guiding catheter, the damaged stent and guiding catheter can be withdrawn together into the radial artery and retrieved successfully by radial artery cutdown and repair method.
冠状动脉支架移位是经皮冠状动脉介入治疗期间一种罕见但严重的并发症。在经桡动脉冠状动脉介入治疗过程中，将移位且变形的支架收回引导导管内困难或无法实现，因为通常使用的是6F的小口径引导导管和鞘管系统。我描述一种在经桡动脉冠状动脉介入治疗期间收回移位且受损支架的新方法。当移位且未展开的支架不能完全回拉到引导导管内时，可将受损的支架和引导导管一起撤回桡动脉，并通过桡动脉切开和修复方法成功取出。
