Advanced limb salvage: Pedal artery interventions.

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Diabetic Limb Complications

Background:

• Chronic limb-threatening ischemia (CLTI) is increasing globally, largely driven by diabetes.
• Diabetic patients often present with tibial and pedal artery disease, complicating limb salvage.
• Traditional surgical bypass may be unsuitable for many CLTI patients due to comorbidities or anatomical issues.

Purpose of the Study:

• To provide a comprehensive review of pedal artery interventions for CLTI.
• To detail the anatomy, techniques, imaging, and outcomes of these endovascular procedures.
• To offer guidance on patient selection and post-intervention surveillance.

Main Methods:

• Review of current endovascular literature focusing on pedal artery interventions.
• Analysis of anatomical considerations, procedural techniques, and intraprocedural imaging modalities.
• Evaluation of clinical outcomes, including pain relief, ulcer healing, and amputation rates.

Main Results:

• Endovascular pedal artery interventions are feasible and safe, offering an alternative to surgery.
• These interventions show promise in relieving ischemic pain and promoting the healing of foot ulcers.
• Successful pedal interventions can reduce amputation rates and improve patient function and quality of life.

Conclusions:

• Pedal artery interventions represent a vital endovascular option for CLTI patients, particularly those with diabetes.
• These techniques expand revascularization possibilities for complex distal arterial disease.
• Further research and standardized surveillance protocols can optimize outcomes for pedal interventions.
