摘要(Abstract)：

目的比较冠状动脉严重钙化病变计划旋磨与非计划旋磨治疗的安全性及有效性。方法连续纳入2014年1月至2017年7月于北京大学人民医院行旋磨治疗的92例患者。根据启动旋磨治疗的时机,分别纳入计划旋磨组(72例)和非计划旋磨组(20例),比较两组患者临床资料、病变特点、手术特点及术后并发症等情况。结果两组患者基线资料匹配,性别、年龄、体重指数、心血管相关危险因素、心功能、既往病史(心肌梗死、经皮冠状动脉介入治疗及冠状动脉旁路移植术)、临床诊断比较,差异均无统计学意义(均P>0.05)。两组患者均以多支病变为主,计划旋磨组(70.8%)与非计划旋磨组(75.0%)比较,差异无统计学意义(P=0.974)。计划旋磨组使用结合血管内超声(intravascular ultrasound,IVUS)和光学相干断层成像(optical coherence tomography,OCT)比例(26.4%比10.0%,P=0.030)显著高于非计划旋磨组,差异有统计学意义。两组患者旋磨靶血管、旋磨头使用情况比较,差异均无统计学意义(均P>0.05)。两组患者支架置入个数及总支架长度比较,差异均无统计学意义(均P>0.05)。但计划旋磨组预扩张球囊用量明显少于非计划旋磨组[1(1,2)个比2(1,3)个,P=0.004],而且手术时间[(81.4±22.7)min比(94.8±33.0)min,P=0.035]、X线照射量[600(492,939)m Gy比840(624,1294)m Gy,P=0.010]及对比剂用量[(227±46)ml比(260±87)ml,P=0.031]均显著低于非计划旋磨组,差异均有统计学意义。计划旋磨组手术即刻成功率显著高于非计划旋磨组(100.0%比85.7%,P=0.001)。术中相关并发症以慢血流、慢心率为主,虽然计划旋磨组并发症发生率(5.4%)低于非计划旋磨组(9.5%),但差异无统计学意义(P=0.493)。结论对于冠状动脉严重钙化病变,应积极应用IVUS和OCT等腔内影像学进行评估,并采取计划旋磨治疗,提高手术成功率,降低手术时间、X线照射量及对比剂用量。
