Background:
The deep inferior epigastric artery perforator (DIEP) flap, often considered the standard in autologous breast reconstruction, is reliant on robust arterial inflow and venous outflow. Venous outflow issues remain a critical part in determining the success of the DIEP flap. Previously, the superficial inferior epigastric vein (SIEV) has been used to augment venous outflow, or as a salvage option when flow through the deep inferior epigastric vein is compromised or insufficient. The authors describe a variant of the DIEP flap, the superficial vein-only DIEP flap, using the deep inferior epigastric artery and the SIEV as a viable alternative when indicated.
Methods:
The authors conducted a retrospective review of all patients undergoing autologous breast reconstruction performed by the senior author (B.C.) from July of 2015 to March of 2020 to identify DIEP flaps whose only source of venous outflow was the SIEV, excluding those performed as salvage maneuvers.
Results:
The authors identified 30 patients (35 flaps) and describe their characteristics, flap characteristics, complications, and details of the flap harvest. Notably, the authors experienced complications in 26.7 percent of flaps, of which 62.5 percent were minor, with no flap loss. This was comparable to the complication rate observed in the standard DIEP flap population.
Conclusions:
The authors believe the superficial vein-only DIEP flap is an excellent option for the appropriate patient. It is an added tool to make abdominally based breast reconstruction more reliable and successful. The use of the SIEV in a superficial vein-only flap should be considered as part of any routine DIEP flap reconstruction.
