Visualized bilateral breast reconstruction by propeller thoracodorsal artery perforator flaps

[Unilateral secondary breast reconstruction using a pedicled dorsal flap sparing the latissimus dorsi (TDAP and MSLD) in patients with a history of total mastectomy for breast cancer. Monocentric observational study]

INTRODUCTION

The use of pedicled dorsal flaps sparing the latissimus dorsi muscle (TDAP and MSLD flap) is a well-described reconstruction method in breast reconstruction after breast cancer. However, little data exists regarding patient satisfaction after this surgery. The main objective of this study was to evaluate patient satisfaction after unilateral total secondary breast reconstruction using a TDAP or MSLD flap. The secondary objectives corresponded to the evaluation of postoperative complications following this surgery, the evaluation of the duration of the reconstruction and the nature of additional interventions, the evaluation of the functional after-effects, and the evaluation of the chest size when the reconstruction is completed.

MATERIAL AND METHOD

This is a monocentric, retrospective cohort study, including 22 patients who underwent unilateral secondary total breast reconstruction using a TDAP or MSLD flap between January 1, 2018 and December 31, 2022. Patient satisfaction was assessed using three questionnaires validated in breast reconstruction: the Reconstruction module of the BREAST-Q, the MBROS-S and the MBROS-BI.

RESULTS

The MBROS-S satisfaction score is 71.4%. The MBROS-BI body image score is 62%. With the BREAST-Q, the Satisfaction with Breast score is estimated at 53.1; the Satisfaction with Back score is estimated at 75.5; the physical well-being score regarding the chest is evaluated at 71.7; the physical well-being score concerning the shoulder and back is evaluated at 67.4; the psychosocial well-being score is assessed at 67.4; the sexual well-being score is estimated at 48.7; and for women who have benefited from reconstruction associated with a prosthesis, the satisfaction score regarding the implant is 71.6.

CONCLUSION

Unilateral total secondary breast reconstruction with a dorsal pedicled flap sparing the latissimus dorsi muscle is an elegant, reliable, and respectful way to reconstruct a breast, and appears to give high levels of satisfaction.

Thoracodorsal artery flaps for breast reconstruction-the variants and its approach

Thoracodorsal artery (TDA) flaps, ranging from the vascular-pedicled thoracodorsal artery perforator (TDAP) flap, the propeller TDAP flap, and the muscle-sparing latissimus dorsi (MSLD) flap to the conventional latissimus dorsi (LD) flap and the extended LD flap, can all be used for breast reconstruction. The aim of this paper and review is to share our experiences and recommendations for procedure selection when applying TDA-based flaps for breast reconstruction. We describe the different surgical techniques and our thoughts and experience regarding indications and selection between these procedures for individual patients who opt for breast reconstruction. We have performed 574 TDA flaps in 491 patients: 60 extended LD flaps, 122 conventional LD flaps, two MSLD flaps, 233 propeller TDAP flaps, 122 TDAP flaps, and 35 free contralateral TDAP flaps for stacked TDAP breast reconstruction. All the TDA flaps are important flaps for reconstruction of the breast. The LD flap is still an option, although we prefer flaps without muscle when possible. The vascular-pedicled TDAP flap is an option for experienced surgeons, and the propeller TDAP flap can be used in most reconstructive cases of the breast, although a secondary procedure is often necessary for correction of the pedicle bulk. The extended LD flap is an option for women with a substantial body mass index, although it is associated with the highest morbidity of all the TDA flaps. The MSLD flap can be used if the perforators are small or if dissection of the perforators is assessed to be hazardous.
