BACKGROUND: The objective of the RANGER II SFA long lesion cohort analysis was to evaluate the safety and effectiveness of the Ranger drug-coated balloon (DCB) in patients with lesion lengths greater than 100 mm.
METHODS: Patients from the RANGER II SFA randomized controlled trial and long balloon sub-study were included in the long lesion cohort if their baseline lesion measurement was > 100 mm and if they had been treated with a RANGER DCB. Patients had symptomatic lower limb peripheral artery disease and Rutherford classification 2-4 symptomatology. The endpoints of interest included the 12-month target lesion primary patency and freedom from major adverse events (MAEs).Additional patient outcomes including changes in Rutherford classification were also evaluated.
RESULTS: A total of 129 patients met the inclusion criteria and were included in the long lesion cohort. Mean lesion length was 144.5 ± 31.7 mm. Seventy-five lesions had Peripheral Arterial Calcium Scoring System (PACSS) grades 3 (33.3%, 43/129) and 4 (24.8%, 32/129). The Kaplan-Meier estimate of the primary patency rate at 12 months was 88.0%. The rate of freedom from MAEs at 12 months was 95.1% (117/123; 95% CI: 89.7%, 98.2%); all MAEs were clinically driven target lesion revascularization (4.9%, 6/123). The 12-month mortality rate was 2.4% (3/125).
CONCLUSIONS: Patients with lesions > 100 mm treated with Ranger DCBs demonstrated excellent 1-year safety and efficacy results, comparable to those of the overall RANGER II SFA randomized clinical trial. This suggests that the Ranger DCB can provide consistent results regardless of lesion length. (ClinicalTrials.gov Identifier: NCT03064126).
