Profundaplasty: its role in limb salvage

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Peripheral Artery Disease

Background:

• The profunda artery functions as a critical collateral system.
• Understanding its role is key to selecting patients for profundaplasty.

Purpose of the Study:

• To evaluate the efficacy of profundaplasty in various peripheral artery disease scenarios.
• To determine optimal indications for profundaplasty, including adjunct and isolated procedures.

Main Methods:

• Analysis of patient outcomes based on the indication for profundaplasty (claudication vs. limb salvage).
• Assessment of profundaplasty's success when combined with arterial inflow procedures versus isolated use.
• Consideration of factors like hemodynamic significance and arteriographic appearance.

Main Results:

• Profundaplasty is highly successful as an adjunct to inflow procedures for aortoiliac and superficial femoral artery occlusive disease, particularly for disabling intermittent claudication.
• Isolated profundaplasty can be effective for limb salvage, healing ulcers, and relieving rest pain, especially with favorable profunda system appearance or low perfusion pressure.
• It is less successful for ischemic gangrene, which may necessitate distal bypass, but can facilitate below-knee amputation by perfusing the knee joint.

Conclusions:

• Profundaplasty is a versatile intervention for profunda artery stenosis, with varying success rates depending on the clinical context.
• It serves as a valuable adjunct for claudication and a potential primary procedure for limb salvage in carefully selected patients.
• Its role extends to optimizing conditions for amputation when limb salvage is not feasible.
