The treatment of coronary artery disease has changed significantly over the last decade. It is estimated that more than 300,000 percutaneous transluminal coronary angioplasty procedures were performed in 1990. Despite advances in angioplasty technique and increased immediate success rates, limitations to treatment remain and have prompted a continuing search for a more effective revascularization device. Rotational ablation performed with a high-speed burr covered with diamond microcrystals has been proven safe and effective in treating coronary lesions. At high speeds the burr preferentially ablates plaque. The particles produced during the procedure are smaller than red blood cells and are readily disposed of by the reticuloendothelial system. This article is an overview of the rotational ablation procedure and related nursing care of the patient.
在过去十年中，冠状动脉疾病的治疗发生了显著变化。据估计，1990年进行了超过30万例经皮腔内冠状动脉成形术。尽管血管成形术技术有所进步，即时成功率有所提高，但治疗仍存在局限性，这促使人们不断寻找更有效的血管重建装置。使用覆盖有金刚石微晶的高速磨头进行的旋磨术已被证明在治疗冠状动脉病变方面是安全有效的。在高速下，磨头优先消融斑块。手术过程中产生的颗粒比红细胞小，很容易被网状内皮系统清除。本文概述了旋磨术及对患者的相关护理。
