Optimal Timing of Delayed Free Lower Abdominal Flap Breast Reconstruction after Postmastectomy Radiation Therapy

Abstract

Patients who underwent delayed abdominal free flap breast reconstruction after 12 months from the completion of postmastectomy radiation therapy developed fewer complications, including microvascular thrombosis and total flap loss, than those who underwent delayed abdominal free flap breast reconstruction within 12 months of completing postmastectomy radiation therapy. Allowing an interval of 12 months between the completion of postmastectomy radiation therapy and delayed abdominal free flap breast reconstruction will likely minimize complications and optimize outcomes in free flap breast reconstruction in patients receiving postmastectomy radiation.
