冠状动脉旋磨术适用于严重钙化病变和球囊无法通过的CTO病变,不适用于血栓性病变、严重成角病变和冠状动脉夹层。经桡动脉旋磨与经股动脉相比,成功率相似,而前者出血并发症更少。旋磨术中,需选择合适的磨头、转速,操作要规范,以避免出现迷走反射、无血流/慢血流、冠状动脉穿孔、分支闭塞、球囊嵌顿等严重并发症。
Coronary atherectomy is suitable for CTO lesions with severe calcification and balloon failure and is not suitable for thrombotic lesions, severe angiographic lesions, and coronary dissections. Transradial rotational atherectomy compared with the femoral artery, the success rate was similar, while the former bleeding less complications. Rotary surgery, the need to select the appropriate grinding head, speed, operation should be standardized to avoid vagus reflex, no blood flow / slow blood flow, coronary perforation, branch occlusion, balloon incarceration and other serious complications.
