In this series, we evaluated the use of rotational ablation in stenoses that were previously refractory to balloon angioplasty. Forty-one stenoses were treated; in 26, the balloon did not adequately expand within the lesion and in 15 the balloon could not be delivered to the stenosis. Rotational ablation was technically successful in 40 of 41 (97.6%) of the lesions attempted. Twenty-four patients have been followed (mean time = 9 +/- 5 months) and the restenosis rate was similar to that of balloon angioplasty. Rotational ablation appears well suited and may be the treatment of choice for heavily calcified, severely angulated, and diffusely diseased vessels.
在本系列研究中，我们评估了旋磨术在既往对球囊血管成形术无效的狭窄病变中的应用。共治疗了41处狭窄病变；其中26处病变球囊在病变部位未能充分扩张，15处病变球囊无法送达狭窄部位。在41处尝试治疗的病变中，有40处（97.6%）旋磨术在技术上取得成功。24例患者得到随访（平均时间=9±5个月），再狭窄率与球囊血管成形术相似。旋磨术似乎非常适合严重钙化、严重成角和弥漫性病变的血管，可能是这类病变的首选治疗方法。
