Summary
Controlled venous bleeding using arteriotomy cannulae can resolve transverse rectus abdominis musculocutaneous flap congestion. This technique improves venous outflow and flap survival during and after breast reconstruction.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Vascular Surgery
Background:
- Transverse rectus abdominis musculocutaneous (TRAM) flaps are used in breast reconstruction.
- Venous congestion can compromise TRAM flap viability intraoperatively and postoperatively.
Observation:
- A novel technique was developed to manage TRAM flap venous congestion.
- Arteriotomy cannulae are inserted into the deep inferior epigastric artery (DIEA) and vein (DIEV).
- Cannulae are externalized for controlled bleeding during and after surgery.
Findings:
- Intermittent venous bleeding from the DIEV aids in improving venous outflow.
- This controlled bleeding allows the flap to adapt to reversed circulation.
- Simultaneous monitoring with a laser Doppler flow meter guides bleeding to balance arterial and venous pressures.
Implications:
- This technique offers a method to proactively manage and potentially prevent TRAM flap congestion.
- Improved flap survival rates in breast reconstruction are anticipated.
- The technique may enhance outcomes for patients undergoing TRAM flap procedures.
