Rotational atherectomy is an indispensable modality for percutaneous coronary intervention of severely calcified lesions. An entrapped rotablator burr is a rare but life-threatening complication because retrieval is difficult. Although emergent surgical removal is a reliable option for this complication, it is invasive. There are various methods to retrieve an entrapped burr by bailout endovascular approaches. We present two cases of successful rescue of stuck rotablator burr entrapment using a Kiwami straight catheter (4 Fr, Heartrail II, Terumo, Tokyo, Japan).
旋磨术是严重钙化病变经皮冠状动脉介入治疗不可或缺的方式。旋磨头卡滞是一种罕见但危及生命的并发症，因为取出困难。尽管紧急手术取出是处理该并发症的可靠选择，但具有侵入性。有多种通过补救性血管内方法取出卡滞旋磨头的方式。我们报告了两例使用Kiwami直导管（4 Fr，Heartrail II，泰尔茂公司，东京，日本）成功挽救卡滞旋磨头的病例。
