Although high-speed rotational atherectomy has been successfully used in selected cases of stent underexpansion secondary to heavy peri-stent calcification, a higher risk of burr entrapment demands extreme caution and surgical back-up on site. The main cause of this complication is the lack of diamond dust on the back end of the burr, which prevents backward ablation of tissues when retracted. To date, only few reports of successful burr retrieval using percutaneous bailout techniques have been published. We report a case of burr entrapment within a previously implanted left circumflex artery stent which was successfully recaptured using the dual catheter technique; following the retrieval the patient underwent routine percutaneous coronary intervention.
虽然高速旋切术已成功应用于支架扩张不全的某些病例，这些病例与支架周围严重钙化有关，但由于钻铤容易被捕获，因此需要格外小心，并在现场做好外科手术准备。造成这种并发症的主要原因是钻铤后端缺少金刚石砂，这会阻碍在回缩时对组织的向后消融。迄今为止，只有少数使用经皮紧急救援技术成功取出钻铤的报道。我们报告了一例左回旋支支架内捕获钻铤的病例，该病例使用双导管技术成功取出；取出后，患者接受了常规经皮冠状动脉介入治疗。
