Limb salvage by extended profunda femoris revascularization

Area of Science:

• Vascular Surgery
• Cardiovascular Medicine
• Peripheral Artery Disease

Background:

• Marked distal ischemia poses challenges in limb salvage.
• The profunda femoris artery's role in maintaining limb perfusion is critical.
• Evaluating revascularization strategies for critical limb ischemia is essential.

Purpose of the Study:

• To assess the efficacy of profunda femoris artery revascularization in patients with severe distal ischemia.
• To determine the success rates of profunda femoris artery revascularization.
• To evaluate the impact of profunda femoris artery revascularization on ischemic symptoms and ulcer healing.

Main Methods:

• Retrospective analysis of patients undergoing profunda femoris artery revascularization.
• Assessment of profunda femoris artery diameter (20-25 cm) as a criterion for intervention.
• Monitoring of clinical outcomes including rest pain, ulcer healing, and ankle pressures.

Main Results:

• Early success, defined by pain relief, ulcer healing, and improved ankle pressures (86%), was observed.
• A significant late success rate of 73% was achieved.
• The profunda femoris artery's adequate descending branch predicted successful revascularization.

Conclusions:

• Profunda femoris artery revascularization is a viable and worthwhile option for patients with marked distal ischemia, provided an adequate artery is present.
• The procedure demonstrates considerable early and late success in improving limb perfusion and healing ischemic complications.
• Distal bypasses can be considered as a secondary option if initial proximal revascularization is unsuccessful.
