Near-total gluteal defect reconstruction with bilateral delayed giant lumbar artery perforator flaps: A case report.

The reconstruction of the near-total or total gluteal defects is challenging. Reconstructive options were restricted when the gluteal flaps were sacrificed. The lumbar artery perforator flap (LAPF) has been recently popularized as an alternative option for sacral and gluteal pressure ulcers. Extension of flap size may be needed in extensive defects. We aim to use the delay phenomenon to increase lumbar artery perforator flap territory to reconstruct near total gluteal defect. A 36-year-old woman was referred to our clinic with defect sizes of 23 × 23 cm and 25 × 17 cm for the right and left gluteal regions. She had a history of multiple surgeries for her paraplegia-related sacrogluteal pressure sores. The reconstruction was started on the left side with delaying incisions to the flap borders. Seven days later, the left gluteal defect was reconstructed with 27 × 19 cm LAPF based on a second lumbar artery perforator. At the same session, the delaying incision was performed to the borders of the right LAPF. On day 14, the right gluteal defect was closed with a 25 × 25 cm-sized right LAPF. No flap loss and early complications were seen. The patient was discharged without complication after 10 days after the last operation. The patient was followed up for 1 year. A right ischial pressure ulcer due to wheelchair use was encountered, which was managed with conservative wound care in the 8th month. Giant-sized lumbar artery perforator flaps may be obtained by delay phenomenon to reconstruct near-total or total gluteal pressure sores.
