Single Versus Multiple Vessels Endovascular Tibial Arteries Revascularization for Critical Limb Ischemia

Overview

This study aims to Compare the outcomes of angioplasty for single tibial vessel occlusion versus multiple tibial vessel occlusions in patients with critical limb ischemia. Assess the effectiveness and safety of angioplasty in treating different extents of tibial vessel occlusions. Evaluate the impact of angioplasty on limb salvage rates, healing of ischemic wounds, and overall clinical improvement in patients with CLI.

This study demonstrates that in patients with chronic limb-threatening ischemia (CLTI), revascularization resulting in the patency of multiple tibial vessels is associated with significantly superior clinical outcomes compared to single-vessel patency. While both strategies were equally safe and technically feasible, the multiple-tibial-vessel (MTV) group achieved perfect limb salvage, higher primary patency, lower restenosis rates, and significantly better wound healing at six months. These findings underscore the importance of robust tibial runoff, supporting the "angiogenic reserve" concept where multiple patent vessels provide redundant perfusion pathways that enhance the durability of revascularization and promote tissue repair. Consequently, when anatomically feasible, treatment strategies should prioritize the establishment or preservation of multi-vessel tibial outflow to optimize limb salvage and functional recovery in this high-risk population.
