Abstract
Purpose:
To compare the outcomes of thromboendarterectomy (TEA) and endovascular therapy (EVT) with stenting for patients with atherosclerotic common femoral artery (CFA) occlusive disease.
Materials and Methods:
From a retrospective registry of 1193 consecutive patients with CFA treatment performed between 2018 and 2020 at 66 institutions in Japan, we identified patients who underwent TEA (n=432) or stent implantation (n=157). The primary outcome measures were the 1-year primary patency of TEA versus stenting with propensity score matching. The secondary outcome measures were perioperative complications, length of hospital stay, any reintervention, limb salvage, and overall survival. Interaction analysis for primary patency was performed with propensity score stratification to determine the appropriate target population for CFA stenting.
Results:
Propensity score matching extracted 101 pairs (101 patients in the EVT group and 253 patients in the TEA group). The 1-year primary patency rate was significantly higher in the TEA cohort (92.8% vs 84.6%, p=0.006). The freedom from reintervention rate was also significantly higher in the TEA cohort (94.0% vs 89.9%, p=0.030). However, the 1-year limb salvage (98.7% vs 100.0%, p=0.32), 1-year overall survival (90.8% vs 85.0%, p=0.14), and frequency of perioperative complications were not significantly different between the cohorts (6.9% vs 14.2%, p=0.10). Based on interaction analysis, the superiority of TEA over EVT in terms of patency was less apparent in patients with advanced age and chronic heart failure.
Conclusions:
Thromboendarterectomy was superior to stenting in terms of primary patency and freedom from revascularization at 1 year. There was no significant difference in the incidence of perioperative complications between both groups. Thromboendarterectomy may be recommended as the standard treatment strategy for patients with atherosclerotic CFA disease, whereas stenting may be considered for patients with advanced age and chronic heart failure.
Clinical Impact
Thromboendarterectomy compared to stenting was the preferred revascularization strategy for patients with CFA disease in terms of primary patency and freedom from target lesion revascularization during the 1st year. The difference was attenuated in subgroups with advanced age (85 years or older) or chronic heart failure, thus stenting may be considered in patients with these backgrounds.
