Combined microvascular breast and lymphatic reconstruction with deep inferior epigastric perforator flap and gastroepiploic vascularized lymph node transfer for postmastectomy lymphedema patients.

BACKGROUND

The combination of microvascular breast reconstruction (MBR) and vascularized lymph node transfer (VLNT) in a single-stage procedure is a surgical option for women who desire breast reconstruction and postmastectomy lymphedema surgery. In this study, we present a series of patients who underwent simultaneous lymphatic and MBR with the gastroepiploic VLNT (GE-VLNT) and the deep inferior epigastric perforator (DIEP) flap respectively.

METHODS

Between 2018 and 2019, all consecutive patients diagnosed with lymphedema stage IIb-III International Society of Lymphology who opted to pursue simultaneous MBR with DIEP flap and GE-VLNT were included in this study. Patient demographics, comorbidities, prior radiation therapy, operative characteristics, surgical outcomes and complications were collected and analyzed.

RESULTS

Six patients underwent simultaneous unilateral MBR with DIEP flap and GE-VLNT. The mean age was 48±10.5 years and mean body mass index was 28.2±4.5 kg/m. The flap survival rate was 100%. One patient required re-exploration due to venous congestion of the lymph node flap but was successfully salvaged. There was no donor site morbidity at the donor or recipient site for the DIEP flap were seen. The mean circumference reduction rate was 30.0%±5.1% (P<0.001). One patient stage III underwent additional liposuction at 12 months postoperative to improve final results.

CONCLUSIONS

The combined use of DIEP flap and GE-VLNT flaps in a single-stage procedure is a safe and reliable surgical option for patients with postmastectomy lymphedema who desire and are suitable for autologous microvascular breast and lymphatic reconstruction.
