Abstract
BACKGROUND: Endovascular therapy (EVT) has become the preferred treatment modality for femoropopliteal disease. However, there is limited evidence regarding its procedural and clinical outcomes according to the affected area.
AIMS: The aim of this study is to investigate clinical outcomes and device effectiveness according to treatment extent in the superficial femoral artery (SFA), popliteal artery (PA), or both.
METHODS: In this study, we analysed EVT for SFA (2,404 limbs), PA (155 limbs), SFA/PA (383 limbs) using the population in the K-VIS ELLA (Korean Vascular Intervention Society Endovascular Therapy in Lower Limb Artery Diseases) registry. The primary endpoint was target lesion revascularisation (TLR) at 2 years.
RESULTS: The SFA/PA group exhibited a higher prevalence of anatomical complexity, characterised by long lesions, moderate to severe calcification, and total occlusion. The procedures were successful in 97.2% of SFA, 92.9% of PA, and 95.6% of SFA/PA EVTs. The 2-year TLR rates were 21.1%, 18.6%, and 32.7% in the SFA, PA, and SFA/PA groups, respectively. SFA/PA EVT was associated with a significantly increased risk for TLR compared to the SFA group (adjusted hazard...
