Feasibility of ischemic leg ulcer healing using percutaneous techniques: a real-life study

Abstract

Background Percutaneous transluminal angioplasty is established as the first-line vascular procedure in patients with lower extremity artery disease. Purpose We aimed to evaluate the technical and clinical effectiveness of percutaneous transluminal angioplasty in the management of ischemic foot ulcers. Material and Methods All consecutive patients presenting with a foot ulcer at the outpatient vascular surgery clinic of our hospital between June 2009 and June 2015 were evaluated using foot pulse assessment, ankle-brachial index, and duplex scanning. If non-invasive parameters suggested lower extremity artery disease, CT angiography and/or digital subtraction angiography were performed and a percutaneous transluminal angioplasty was carried out when feasible during the same session. All patients were followed until healing, amputation, death, or for at least two years. Short- and long-term clinical success was evaluated based on ulcer size and appearance. Patients with worsening ulcers after percutaneous transluminal angioplasty underwent bypass grafting or amputation. Results Percutaneous transluminal angioplasty was performed in 161 patients (100%) with stenoses > 50%, including cases lesions > 10 cm and/or multiple/calcified lesions, 144 of which completed the study. In 88 (61.2%) patients, percutaneous transluminal angioplasty was performed in the suprapopliteal axis exclusively, in 10 (6.8%) patients in the infrapopliteal axis only, and in 46 (31.9%) in both levels. Percutaneous transluminal angioplasty was technically successful in 141 (98%) patients. After 3.1 years, the rate of healing was 68%, limb salvage 88%, overall survival 69.5%, and amputation-free survival 64%. Conclusion Our data suggest that percutaneous transluminal angioplasty for ischemic foot ulceration treatment is in the majority of patients feasible, effective, and safe with high rates of healing and limb salvage.
