Simultaneous bilateral breast reconstruction with in-the-crease inferior gluteal artery perforator flaps

The inferior gluteal artery perforator (IGAP) free flap represents an alternative technique for autogenous breast reconstruction in patients with insufficient abdominal donor tissue. Historically, patients underwent a staged approach for bilateral breast reconstruction with the IGAP because it is technically demanding and can be time consuming. The bilateral simultaneous IGAP can be performed effectively with 2 microsurgeons operating together. This is a retrospective study of 22 patients (44 flaps) who underwent bilateral breast reconstruction with bilateral IGAP flaps in one operation between January 2005 and December 2007. The following parameters were evaluated and compared to our published data with unilateral IGAP flap reconstruction: operating time, blood loss, flap weight, hospital length of stay, and perioperative complications. A follow-up patient survey was also conducted to gauge patient's satisfaction with the donor site and procedure. The flap survival rate was 100%. Complications included 1 patient with 1 flap with partial fat necrosis, 2 patients who required reoperation for venous congestion, 1 patient with a hematoma, 2 patients with delayed buttock wound healing, 2 patients requiring resuturing for buttock wound dehiscence, and 1 patient with resolved paresthesias. The majority of patients were satisfied with the procedure and donor site. In this study, we detail our experience with the inferior gluteal region as a reliable source of donor tissue and the simultaneous bilateral IGAP flap as an efficient method of breast reconstruction.
