Isolated Metatarsal Artery Balloon Angioplasty for Toe Salvage in Critical Limb Ischemia: A Case Report
Isolated metatarsal artery angioplasty
Abstract
Purpose: To report a case of percutaneous balloon angioplasty (PTA) performed in the second metatarsal artery for treatment of a non-healing forefoot wound without proximal intervention.
Methods and Results: An 80-year-old diabetic woman with a 1.5-year history of a non-healing right second digit ulcer refractory to conservative management underwent a lower extremity arteriogram. Angiography demonstrated unobstructed flow from the aortic bifurcation through to the pedal arch, with an isolated occluded segment in the second metatarsal artery wound supply. This was treated with 1.5 mm balloon angioplasty, with completion angiography demonstrating restored flow to the wound base. There were no procedural events and the wound completely healed after 9 months.
Conclusion: Isolated angioplasty of the arteries distal to the pedal arch may be technically feasible and clinically valuable in selected cases.
