Background
There is limited evidence regarding the impact of disease extent level on clinical outcomes following endovascular therapy for femoropopliteal disease.
Methods
The K-VIS ELLA (Korean Vascular InterventionSociety Endovascular Therapy in Lower Limb Artery Diseases) registry enrolledpatients diagnosed with lower extremity PAD undergoing EVT at 19 cardiovascularcenters in Korea since 2006 (ClinicalTrials.gov identifier: NCT02748226). The study population was subsequently divided intothree distinct groups based on the extent of disease involvement in the targetlimbs treated with EVT: 1) EVT for the SFA (SFA-only group: 2493 limbs [1920patients]), 2) EVT for the POP (POP-only group: 169 limbs [131 patients]), and3) EVT for both SFA and POP (SFA+POP group: 422 limbs [300 patients]). The primary endpoint of the study was target lesionrevascularization (TLR), which was defined as any subsequent interventionperformed within a 5 mm segment proximal or distal to the initially treated targetsegment during follow-up, with more than 50% angiographic diameter stenosis,accompanied by worsening symptoms and a decline >0.15 in the ankle-brachialindex in comparison to the immediate postprocedural ankle-brachial index.
Results
The mean age of the study population was 69.4years, with 2,499 individuals (81%) being male. The technical success rates were 97.2%, 93.5%, and95.7% in the SFA-only, POP-only, and SFA+POP groups, respectively (p = 0.015). During 2 years of follow-up, TLR occurred in 379 limbs(21.5%) in the SFA-only group, 23 limbs (19.5%) in the POP-only group, and 93limbs (32.9%) in the SFA+POP group (p <0.001). In multivariable Cox proportional model withmultiple comparison, SFA+POP group was associated withincreased risk of TLR compared to SFA-only group (adjusted HR 1.45, 95% CI1.09–1.94, P = 0.007) and POP-only group (adjusted HR 1.69, 95% CI 0.97–2.96, P= 0.069). There was no difference in the risk of TLR between SFA-only andPOP-only groups.
Conclusion
In this study, the rate of TLR was highest in the SFA+POP group after endovascular therapy femoropopliteal disease. This TLR risk was similar between SFA-only and POP-only intervention group.
