正向夹层再入真腔技术在慢性完全闭塞病变介入治疗中的应用体会

Primary experience of antegrade dissection reentry technique used in percutaneous coronary intervention for chronic total occlusion lesion

慢性完全闭塞(CTO)病变目前被认为是经皮冠状动脉介入治疗最后的堡垒。很多技术被发明应用于CTO的治疗。Stingray球囊辅助下正向夹层再入真腔技术目前是CTO介入治疗的主要方法之一。适时启动ADR、术中预防控制血肿有利于提高ADR成功率和手术效率。ADR的成功率和长期预后并不劣于正向和逆向技术。在适合的CTO患者和病变中尽早启动,术中注意血肿形成,规范操作能够提高ADR成功率,改善患者预后。

Until to now chronic total occlusion(CTO)lesion is still regarded as the final frontier("final fortress")of percutaneous coronary intervention(PCI).A lot of techniques have been invented and used in PCI of CTO.Stingray balloon assistant antegrade dissection reentry(ADR)is one of main techniques for PCI of CTO.Staring ADR at appropriate time and preventing and controlling subintimal hematoma benefit success and efficacy of ADR.Long-term prognosis and success rate of ADR is not inferior than antegrade and retrograde techniques.Starting ADR as early as possible in appropriate lesions and patients and controlling the hematoma and standardized operation during ADR procedure can improve ADR success rate and prognosis of patients with CTO lesions.
