How a Green Dye Might Help in Breast Reconstruction
The Challenge of Mastectomy Skin Flap Necrosis (MFN)
Breast reconstruction after a mastectomy can sometimes lead to tissue damage, known as mastectomy skin flap necrosis (MFN). This complication occurs in 7-40% of cases, causing healing delays and potential treatment setbacks.
A Promising Solution: Indocyanine Green (ICG) Dye
Doctors have started using a green dye called indocyanine green (ICG) to help visualize tissue perfusion during surgery. This allows surgeons to assess how well the tissue is receiving blood.
Study on ICG Imaging and DIEP Reconstruction
A recent study examined how ICG imaging, combined with a scoring system, affects MFN rates in immediate deep inferior epigastric perforator (DIEP) breast reconstruction. The goal was to determine a safe level of tissue perfusion to guide surgeons in deciding how much tissue to remove.
Key Findings
- ICG imaging helps surgeons better assess tissue perfusion during the procedure.
- The hope is that this will lead to fewer cases of MFN and better outcomes for patients.
- The study aimed to meet national benchmarks for breast reconstruction outcomes.
Limitations and Future Research
While ICG imaging is not new, the optimal level of tissue perfusion for resection remains debated. This study provides valuable insights, but it was conducted at a single center, meaning results may vary in different settings. More research is needed to confirm these findings.
Conclusion
For now, the use of ICG imaging and perfusion scoring shows promise in reducing the risk of tissue damage in breast reconstruction.
