Stentablation by rotational atherectomy has been reported as an option to correct underexpanded stents. Due to concerns of excessive stent damage, distal embolization of metal particles, excessive heat generation, and burr entrapment in the stent, stentablation has been considered the last choice to manage underexpanded stents. Here, we report a case of a stuck and entrapped atherectomy burr inside an underexpanded and undilatable stent, which made withdrawal of therotablation burr during rotational atherectomy difficult. After successful stentablation by rotational atherectomy, we were able to complete the percutaneous coronary intervention with another stent.
据报道，通过旋磨术进行支架消融是纠正支架扩张不足的一种选择。由于担心支架过度损伤、金属颗粒远端栓塞、过多热量产生以及磨头被困在支架中，支架消融一直被视为处理支架扩张不足的最后选择。在此，我们报告一例病例，在一个扩张不足且无法扩张的支架内，旋磨磨头卡住并被困，这使得在旋磨术中撤回旋磨磨头变得困难。通过旋磨术成功进行支架消融后，我们得以用另一枚支架完成经皮冠状动脉介入治疗。
