Basic fibroblast growth factor induced angiogenesis and prefabricated flap survival

Area of Science:

• Regenerative Medicine
• Tissue Engineering
• Surgical Innovation

Background:

• Latissimus dorsi myocutaneous flaps are crucial in reconstructive surgery.
• Enhancing flap survival and vascularization is a key challenge.
• Growth factors offer potential for improving tissue regeneration.

Purpose of the Study:

• To evaluate the efficacy of basic fibroblast growth factor (bFGF) in prefabricating latissimus dorsi myocutaneous flaps.
• To assess the impact of bFGF on flap survival and angiogenesis.
• To determine the feasibility of using Gelfoam sponges as a bFGF delivery system.

Main Methods:

• Prefabrication of latissimus dorsi myocutaneous flaps in adult male Landrace pigs.
• Utilizing Gelfoam sponges for localized delivery of bFGF at the muscle-subcutaneous tissue interface.
• Comparative analysis of flap survival and angiogenesis between bFGF-treated and control groups.

Main Results:

• Significant augmentation of skin survival in flaps treated with bFGF.
• Enhanced angiogenesis (new blood vessel formation) observed in growth factor-treated animals.
• Gelfoam sponges effectively served as a delivery system for bFGF.

Conclusions:

• Basic fibroblast growth factor (bFGF) significantly improves latissimus dorsi myocutaneous flap prefabrication.
• bFGF promotes enhanced skin survival and angiogenesis, crucial for flap viability.
• Gelfoam sponge delivery of bFGF is a viable strategy for improving reconstructive surgical outcomes.
