Detachment and fracture of intravascular ultrasound (IVUS) catheters is an infrequent complication during percutaneous coronary intervention (PCI). This report describes the successful retrieval of a fractured IVUS catheter tip from the left anterior descending artery (LAD) using the guidewire braiding technique after rotational atherectomy. To our knowledge, this is the first report of rotational atherectomy being used when the protective sheath of the IVUS catheter is left in the coronary artery.
血管内超声(IVUS)导管的分离和断裂是经皮冠状动脉介入治疗(PCI)期间罕见的并发症。本报告描述了在旋磨术之后,使用导丝编织技术成功从左前降支(LAD)取出断裂的IVUS导管尖端。据我们所知,这是IVUS导管保护鞘留在冠状动脉内时使用旋磨术的首例报告。
