A 70-year-old patient underwent percutaneous transluminal coronary angioplasty of a calcified tight mid-right coronary artery lesion, when the balloon burst and could not be retrieved. Even on cardiopulmonary bypass, the catheter could not be extracted through a proximal aortotomy. The patient had a distal reversed saphenous vein graft inserted into the right coronary artery. The catheter was ultimately removed after an endarterectomy of the calcified lesion.
一名70岁患者接受经皮腔内冠状动脉成形术，处理右冠状动脉中段一处钙化严重的狭窄病变时，球囊破裂且无法取出。即便在体外循环下，也无法通过近端主动脉切开术取出导管。于是为患者在右冠状动脉植入了一段远端翻转的大隐静脉移植血管。最终在对钙化病变进行动脉内膜切除术后，导管被取出。
