冠状动脉斑块旋磨术联合血管内碎石术治疗冠状动脉严重钙化3例

Coronary rotational atherectomy combined with intravascular lithotripsy for treating severe coronary artery calcification:Report of 3 cases

冠状动脉钙化(coronary artery calcification,CAC)常见于糖尿病、代谢综合征及慢性肾脏病患者,其进展可反映全身炎症状态,且与经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)支架内血栓形成或再狭窄等不良结局有关。CAC增加PCI难度,通常需修饰钙化灶以保证顺利输送和扩张药物洗脱支架。
