Shape-modified radial artery perforator flap method: analysis of 112 cases

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Microsurgery

Background:

• Radial forearm flaps can cause donor-site morbidity.
• Perforator flap techniques aim to reduce this morbidity.
• This study evaluates a novel shape-modified radial artery perforator flap.

Purpose of the Study:

• To analyze the efficacy and safety of the shape-modified radial artery perforator flap.
• To assess flap survival and reconstructive outcomes.
• To evaluate donor-site morbidity associated with this technique.

Main Methods:

• Retrospective analysis of 112 cases using the shape-modified radial artery perforator flap.
• Evaluation of injury cause, recipient site, flap type (free/pedicled), size, and perforator division.
• Assessment of flap survival, aesthetic outcomes, and donor-site complications (scars, numbness).

Main Results:

• Reconstructions were performed on head and neck, upper, and lower extremities.
• Flap survival rate was 97.3% (109/112), with three free flaps experiencing venous thrombosis.
• Excellent or good aesthetic outcomes were achieved in 97.4% of cases, with minimal donor-site morbidity.

Conclusions:

• The shape-modified radial artery perforator flap is a versatile, safe, and effective reconstructive method.
• It demonstrates high flap survival and excellent aesthetic results with low donor-site complications.
• The technique is suitable for a wide range of patients, including pediatric and geriatric populations.
