Endovascular therapy (EVT) with devices such as drug-coated balloons (DCBs) and drug-eluting stents (DESs) for atherosclerotic disease in the femoropopliteal (FP) artery has been established. However, EVT using drug-based devices for chronic limb-threatening ischemia (CLTI) remains challenging. The optimal device for FP lesions in patients with CLTI remains unknown. This study compared the clinical efficacy of DCB and DES in patients with CLTI and FP lesions.
This retrospective single-center study included 539 consecutive patients (562 lesions) treated with EVT between January 2018 and December 2022; 166 patients with CLTI and Rutherford Class 5 or 6 wounds underwent EVT with DCB or DES. Clinical outcomes were compared between 53 pairs after propensity score matching. There were no significant differences between the DCB and DES groups in the incidence of complete wound healing without death or major amputation (84.8% vs. 80.2%, respectively; P=0.99), primary patency (69.4% vs. 75.6%, respectively; P=0.65), and freedom from target lesion revascularization at 1 year (78.6% vs. 78.0%, respectively; P=0.92). Multivariate analysis showed that complete wound healing at 1 year is negatively associated with hemodialysis and Wound, Ischemia, and foot Infection Stage 4, but positively associated with Global Limb Anatomic Staging System FP Grade 3 or 4.
No significant differences in clinical outcomes were found between DCB and DES for patients with CLTI and FP lesions.
在股腘动脉(FP)的动脉粥样硬化病变中,使用药物涂层球囊(DCB)和药物洗脱支架(DES)等设备的血管内治疗(EVT)已经确立。然而,对于慢性肢体威胁性缺血(CLTI)患者使用基于药物的设备进行 EVT 仍然具有挑战性。对于 CLTI 患者的 FP 病变,最佳的设备仍不清楚。本研究比较了 DCB 和 DES 在 CLTI 合并 FP 病变患者中的临床疗效。
这是一项回顾性单中心研究,纳入了 2018 年 1 月至 2022 年 12 月期间接受 EVT 治疗的 539 例连续患者(562 处病变);其中 166 例 CLTI 患者和 Rutherford 5 或 6 级伤口接受了 DCB 或 DES 治疗的 EVT。在倾向评分匹配后,比较了 53 对患者的临床结果。在 DCB 组和 DES 组之间,没有观察到完全伤口愈合且无死亡或主要截肢的发生率(分别为 84.8%和 80.2%;P=0.99)、一期通畅率(分别为 69.4%和 75.6%;P=0.65)和 1 年时免于靶病变血运重建的比例(分别为 78.6%和 78.0%;P=0.92)之间存在显著差异。多变量分析表明,1 年时完全伤口愈合与血液透析和伤口、缺血和足部感染 4 期呈负相关,但与 Global Limb Anatomic Staging System FP 分级 3 或 4 呈正相关。
在 CLTI 合并 FP 病变患者中,DCB 和 DES 的临床结局无显著差异。
