Short and long-term outcome after common femoral artery hybrid procedure in patients with intermittent claudication and chronic limb threatening ischemia.

Abstract

Background: This study aimed to evaluate the differences between the outcomes of patients with intermittent claudication (IC) and chronic limb threatening ischemia (CLTI) who underwent a hybrid procedure comprising common femoral artery endarterectomy and endovascular therapy. Patients and methods: This was a retrospective single-center study of all patients with peripheral arterial occlusive disease (PAD) who underwent the hybrid procedure between March 2007 and August 2018. The primary endpoint was primary patency after 7 years. The secondary endpoints were primary-assisted patency, secondary patency, limb salvage, and survival. Results: During the follow-up period, 427 limbs in 409 patients were treated. A total of 267 and 160 patients presented with clinical signs of IC and CLTI, respectively. The 30-day mortality was 1.4% (IC: 0% vs. CLTI: 3.8%, p=0.001). The overall 30-day major amputation rate was 1.6% (IC: 0% vs. CLTI: 4.4, p=0.001). The rates of primary and secondary patency after 7 years were 63% and 94%, respectively, in the IC group and 57% and 88%, respectively, in the CLTI group; the difference was not significant. Limb salvage (94% vs. 82%, p=0.000) and survival (58% vs. 29%, p=0.000) were significantly higher in the IC group. In a multivariate analysis, CLTI was the only risk factor for major amputation. CLTI and single vessel run-off were risk factors for death. Statin therapy was a protective factor. Conclusions: The hybrid procedure provides excellent results as a treatment option for multilevel lesions in patients with PAD. However, patients with CLTI had a shorter long-term survival and lower limb salvage rate.
