Comparison of Endovascular Interventions for the Treatment of Superficial Femoral Artery Disease: A Network Meta-analysis

Abstract

Background: To understand the relative safety and efficacy of endovascular treatment modalities used for superficial femoral artery (SFA) disease, we performed a network meta-analysis to compare outcomes between percutaneous transluminal angioplasty (PTA), atherectomy (A), bare metal stent (BMS), brachytherapy/radiotherapy, covered stent graft (CSG), cutting balloon angioplasty (CBA), drug-coated balloon (DCB), drug-eluting stent (DES), and intravascular lithotripsy (L). Methods: We performed a systematic literature search of PubMed from January 2000 to January 2023 to identify randomized trials comparing endovascular interventions for the treatment of SFA disease. The primary end points were technical success and 12-month primary patency. Results: In total, 57 studies (9089 patients) were included. The mean age of the included patients was 68.4 years, 41.4% had diabetes, 18.3% had critical limb ischemia, and 81.3% had de novo lesions. A mean of 1.2 lesions were treated per patient. Technical success was superior for CSG, BMS, and A+DCB compared with PTA, while A+DCB and CSG were superior to DCB. All interventions except brachytherapy alone had superior primary patency compared with PTA. There were no significant differences in 12-month mortality or major amputation. All interventions except L+DCB, PTA+A, and CBA were superior to PTA regarding target lesion revascularization, while only DCB, DES, and BMS were better than PTA at improving Rutherford classification. Conclusions: In SFA disease, PTA alone is mostly inferior to other endovascular techniques. This comparison of other endovascular techniques will be valuable for endovascular device selection in the treatment of SFA disease.
