摘要 目的探讨严重冠状动脉钙化的患者在血管内超声显像(intravenous ultrasound,IVUS)指导下行冠状动脉旋磨后再行药物洗脱支架置入治疗的安全性和有效性。方法回顾性分析2015年1月至2016年3月河南省焦作市人民医院27例冠状动脉严重钙化患者在IVUS指导下行冠状动脉旋磨及支架置入术,评估手术即刻成功率、术后管腔最小直径、最小直径狭窄率、管腔有效面积变化及随访结果。结果27例患者中,术前、术后肌钙蛋白T、肌酸激酶同工酶与肌酸酐比较,差异无显著性(P>0.05)。靶血管旋磨及支架置入后,最小管腔直径由术前的(1.563±0.061)mm增大至(3.293±0.073)mm;直径狭窄率由术前的(84.07±1.195)%降至(43.7±1.954)%;管腔有效面积由术前的(3.5±0.139)mm^(2)增至(9.859±0.262)mm^(2),差异均有显著性(P<0.05)。即刻手术成功率100%,术后随访无心血管事件发生。结论对严重冠状动脉钙化的患者,在IVUS指导下行冠状动脉旋磨及支架置入术,减少了严重并发症发生,提高了手术成功率和安全性。
