摘要(Abstract):
目的 评价自制圈套器在冠状动脉慢性完全闭塞(CTO)病变逆向介入治疗中的有效性和安全性。方法 连续入选2018年1月至2022年6月冠状动脉CTO病变逆向介入治疗患者74例,自制圈套器组32例使用自制圈套器辅助完成导丝体外化,无圈套器组42例采用逆向导丝直接进入指引导管完成导丝体外化。分析两组患者的临床基本资料、CTO病变特点、导丝体外化时间、成功率和并发症发生情况。结果 使用自制圈套器组比无圈套器组能更高效地完成导丝体外化[(6.8±1.2)min比(8.9±1.8)min,P<0.001],且成功率更高(100.0%比85.7%,P=0.026)。使用自制圈套器组发生术后心脏压塞1例,两组手术并发症发生率的差异无统计学意义(P=0.432)。结论 CTO病变的逆向介入治疗过程中应用自制圈套器协助完成逆向导丝体外化具有安全、高效的特点,可提高逆向介入治疗的成功率。
