| 中文摘要: |
| 血管内治疗用于下肢外周动脉疾病（PAD）时，血管准备质量与即时管腔获得、药物涂层球囊贴壁及后续植入补救性支架密切相关。基于外部镍钛限制结构形成的受控节段性扩张，理论上以巧克力球囊为代表的约束型球囊可降低局部应力集中、减少严重夹层发生风险和补救性植入支架。本文重点围绕严重/限流性夹层发生率、补救性植入支架、一期通畅率、临床驱动靶病变血运重建（CD-TLR）、保肢率及无截肢生存率而对约束型球囊用于下肢PAD研究进展进行综述。 |
| 英文摘要: |
| The quality of vessel preparation is closely related to immediate lumen gain， drug-coated balloon apposition and subsequent rescue stenting in endovascular therapy for lower extremity peripheral arterial disease （PAD）. Constrained balloons， represented by Chocolate balloon， can form controlled segmental expansion based on their external nickel titanium confinement structure， hence theoretically reducing local stress concentration， the risk of severe dissection and remedial stent placement. The research progresses of constrained balloons for lower extremity PAD， focused on the incidence of severe/flow limiting dissection， remedial stent placement， primary patency rate， clinically driven target lesion revascularization （CD-TLR）， limb salvage rate and amputation free survival rate， were reviewed in this article. |
