What Researchers Did
Researchers reported a case of unexpected severe skin necrosis following autologous transverse rectus abdominis musculocutaneous (TRAM) flap breast reconstruction in a patient with a specific genetic deficiency.
What They Found
They found that a 46-year-old woman developed extensive abdominal skin necrosis and partial flap necrosis on the reconstructed breast by the 5th postoperative day after TRAM flap surgery. This patient was homozygous for the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene, a deficiency hypothesized to be the cause of the severe necrosis.
What This Means for Canadian Patients
Patients undergoing TRAM flap breast reconstruction should be carefully selected, with thorough preoperative planning and investigations to minimize complications. While routine MTHFR gene testing is not recommended due to its rarity, it could be considered in cases of unexpected and extensive postoperative necrosis.
Canadian Relevance
This case report has no direct Canadian connection.
Study Limitations
As a case report, the findings are limited to a single patient and may not be generalizable to a broader population.
