Role of Pedal Arteries Angioplasty as a Limb Salvage in Patients with Critical Lower Limb Ischemia

Background: Worldwide, an estimated 237 million people suffer from peripheral arterial disease (PAD). Coronary artery and cerebrovascular disease are two more cardiovascular diseases that are known to be related to PAD, which is a major cause of morbidity. Aim and objectives: To assess the clinical results, wound healing speed, and amputation-free survival rates of patients with critical limb ischemia, pedal arch angioplasty's efficacy and function in limb salvage must be determined. Patients and methods: Fifty patients participated in this prospective, randomized, controlled trial; each case was evaluated separately, and patients were randomly assigned to have infrapopliteal artery angioplasty or pedal artery angioplasty. Between August 2022 and August 2023, researchers from Cairo's Al-Azhar University Hospitals (Al-Hussein and Sayed Galal University Hospitals) and Kobri El Kobba Hospital carried out the study. Results: Endovascular arterial revascularization is a first-line therapeutic option for high-risk populations. It helps save limbs and improves patients' quality of life. Conclusion: Pedal-plantar arch angioplasty should be considered for patients who do not show adequate wound blushing during conventional above-ankle angioplasty. One or more tibial arteries extending to the pedal arch must be open for pedal arch angioplasty. Patients with chronic limb injury (CLI) can benefit from below-the-ankle angioplasty in several ways, including faster wound healing, limb salvage, and amputation-free survival rates.
