Venous flaps

Area of Science:

• Plastic Surgery
• Surgical Innovation
• Vascular Biology

Background:

• The principle of continuity is fundamental to flap survival, historically interpreted as vascular continuity based on the Harvesian model.
• Flap classification (random, axial) traditionally relies on the Harvesian circulation model for survival mechanisms.
• Recent reports introduce 'venous flaps,' which appear to deviate from the classical Harvesian model of circulation.

Purpose of the Study:

• To review existing data on venous flaps.
• To provide guidance for future research and clinical applications of venous flaps.
• To explore the physiological basis of survival in venous flaps, potentially challenging established theories.

Main Methods:

• Literature review of studies on venous flaps.
• Analysis of reported cases and experimental data on venous flap survival.
• Comparison of venous flap physiology with the classical Harvesian model.

Main Results:

• Venous flaps represent a novel category where the Harvesian model of circulation is not overtly apparent.
• Existing data suggests alternative mechanisms may be responsible for venous flap survival.
• Further investigation is needed to fully elucidate the physiological underpinnings of venous flap viability.

Conclusions:

• The concept of continuity remains central to flap survival, but its interpretation may need expansion.
• Venous flaps present a paradigm shift, necessitating a re-evaluation of traditional flap survival principles.
• Continued research into venous flaps is crucial for advancing reconstructive surgery and understanding tissue viability.
