Deep inferior epigastric vessels for free scapular flap phalloplasty

Abstract

We aimed to present our 20-year experience of using the deep inferior epigastric vessels as recipient vessels for free scapular flaps phalloplasty and evaluate the outcomes. Penile reconstruction was performed using a free scapular flap between 2000 and 2020 by the same surgical team. Deep inferior epigastric vessels were used in all the cases. The surgical techniques and outcomes were described. Overall, 73 patients used the deep inferior epigastric artery (DIEA) as the recipient artery. Regarding the recipient veins, 2 veins were anastomosed in 72 (98.6%) patients, 1 deep inferior epigastric vein (DIEV) was used in 1 patient, 2 DIEV in 14, 1 DIEV + superficial inferior epigastric vein (SIEV) in 13, 1 DIEV + superficial circumflex iliac vein (SCIV) in 38, great saphenous vein (GSV) + SCIV in 4, and GSV + SIEV in 3. The mean age and body mass index of the study cohort was 28 years and 24.3 kg/m2, respectively. The shortest follow-up time was 7 months. Eleven patients had flap-related complications. Three patients were readmitted to the operating room within 24 hours, and 2 of them underwent salvage procedures with venous revision. Two patients lost the entire flap. One patient with 3-cm distal portion necrosis required surgical intervention. Three patients experienced urethral necrosis. DIEA is a suitable receptor artery for inflow. The DIEV, SIEV, and SCIV are available options for venous drainage according to the patient anatomical characteristics. The GSV can be an excellent backup for outflow and salvage procedures.
