In recent years, the emergence of some special balloons, such as pressure-focused balloon: cutting balloon, double/triple guide wire balloon, scoring balloon and constrained balloon (also called chocolate balloon), has significantly improved the pre-dilation of peripheral stenosis, and greatly improved the immediate success rate of the procedure and long-term prognosis. However, for some fibrotic or calcified lesions, it is difficult to achieve adequate dilatation with ordinary balloons, resulting in a poor prognosis for patients. Compared with ordinary balloon, special balloon has the following advantages in clinical application: ① fibrotic plaque and calcified lesions: for elastic fibre-dense fibrotic plaque and hard texture calcified lesions, ordinary balloon has the problem of high dilatation resistance, poor dilatation effect, and also increases the risk of vascular tear, perforation, and no re-flow during the operation. Special balloons such as cutting and scoring can better anchor the lesion, directionally cut fibrous plaques and calcified rings, fully squeeze the plaque, reduce elastic retraction, and significantly increase the minimum lumen area and immediate lumen rate. 近年来,一些特殊球囊,如压力聚焦型球囊:切割球囊、双导丝/三导丝球囊、刻痕球囊和约束型球囊(也叫巧克力球囊)等的出现,明显改善了外周血管狭窄预扩张的效果,大大提高了手术即刻成功率及远期预后。然而,对于一些纤维化或者钙化病变,普通球囊难以达到充分扩张的目的,导致患者预后不良。特殊球囊相较普通球囊,在临床应用中有如下优势:①纤维化斑块和钙化病变:对于弹力纤维密集的纤维斑块和质地坚硬的钙化病变,普通球囊存在扩张阻力大、扩张效果差的问题,操作过程中还会增加血管撕裂、穿孔和无复流等风险。切割、刻痕等特殊球囊能更好地锚定病变,定向割断纤维斑块和钙化环,充分挤压斑块,减小弹性回缩,显著增加最小管腔面积与即刻管腔率。
