Summary
This study introduces a new vascular zoning method for rectus abdominis myocutaneous (RAM) flaps, improving security in reconstructive surgery. The revised classification reduced partial flap necrosis, enhancing patient outcomes.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Surgical Oncology
Background:
- Rectus abdominis myocutaneous (RAM) flaps are widely used in reconstruction.
- Common flap designs include transverse (TRAM), vertical (VRAM), and oblique (ORAM).
- Partial flap necrosis is a frequent complication.
Purpose of the Study:
- To introduce a novel vascular zoning method for rectus abdominis myocutaneous flaps.
- To revise abdominal wall perfusion classification for pedicled TRAM flaps.
- To enhance the security and reduce complications of RAM flaps.
Main Methods:
- Prospective data collection on cutaneous vascularization of 70 pedicled RAM flaps in 68 patients (Feb 2009-Feb 2013).
- Analysis of clinical data and photographic records.
- Retrospective evaluation of results, literature review, and design modifications.
Main Results:
- No flap complications observed in VRAM, TV RAM, or ORAM flaps.
- Three instances of partial necrosis occurred in TRAM flaps, prompting a change in approach.
- The new method aimed to exclude doubtful vascular territories.
Conclusions:
- Abdominal skin perfusion was discussed based on literature and clinical experience.
- A revised vascular classification was proposed.
- Safer skin paddles are achievable with the proposed classification.
