Delayed breast reconstruction with transverse latissimus dorsi myocutaneous flap using Becker expander implants in patients submitted to radiotherapy: A series of cases

BACKGROUND

Breast reconstruction with a latissimus dorsi myocutaneous flap associated with a breast implant is a well-established procedure. However, there are few published articles regarding latissimus association with expanders and radiotherapy. This study assess data of breast reconstructions using a latissimus dorsi myocutaneous flap associated with Becker expander implant (TLDMF/E) in patients submitted to radiotherapy.

METHODS

This is a descriptive study consisting of a series of cases. Inclusion criteria were patients who underwent mastectomy, radiotherapy, and delayed LDMF/E breast reconstruction. A minimum 6-month follow-up period was established, and descriptive variables were analyzed.

RESULTS

One hundred twenty-three patients were selected. The mean age of the patients was 45.1 years. Contralateral breast procedures were performed in 68 patients to achieve symmetry with substitution of the expander for an implant, with the majority of patients with an implant larger than the expander (74.0%) The nipple-areola complex was reconstructed in 77 patients (62.6%). In the donor site area, 116 patients (94.3%) had no complications. Minor complications were seroma in one patient and partial dehiscence in another patient. In the reconstructed breast, 11 patients (8.9%) had minor complications such as hematomas, partial necrosis of the native irradiated breast skin (3 cm or smaller), local infections, and partial exposition of the injection port. Major complications in the reconstructed breast were necrosis (larger than 3-5 cm) of the native irradiated breast skin in 5 patients (4.0%) who needed repair to avoid exposure of the expander. One patient needed expander removal due to a larger exposition.

CONCLUSIONS

Delayed breast reconstruction with TLDMF/E is a reliable option to selected patients with mastectomy and radiotherapy sequel.

Patient satisfaction with breast reconstructionusing musculocutaneous flap from latissimus dorsiversus from rectus abdominis: a cross-sectional study

BACKGROUND

Breast cancer is the second most frequent type of cancer worldwide and the most common type among women. The treatment for this condition has evolved over recent decades with therapeutic and technological advances. Breast reconstruction techniques using musculocutaneous flaps from the latissimus dorsi and rectus abdominis have aroused interest regarding patients' quality of life. Our goal here was to compare patients' satisfaction scores after they underwent breast reconstruction using musculocutaneous flaps from either the latissimus dorsi or the rectus abdominis.

DESIGN AND SETTING

Primary, clinical, analytical, observational and cross-sectional study conducted in a federal university and a public hospital.

METHODS

Demographic and clinical data were collected. The Mini-Mental State Examination was then applied, with testing for specificity and sensitivity. Lastly, a breast evaluation questionnaire was applied to evaluate breast satisfaction among 90 women, who were divided into three groups: mastectomy (control; n = 30); breast reconstruction using flap from the latissimus dorsi (n = 30); and reconstruction using flap from the rectus abdominis (n = 30).

RESULTS

The groups were homogeneous regarding the main demographic data and the questionnaire responses (P < 0.05). Compared with the control group, the reconstruction groups showed significant improvement in satisfaction (P < 0.0002) after one year.

CONCLUSION

Within our sample, women who underwent breast reconstruction with flaps from either the latissimus dorsi or the rectus abdominis had similar satisfaction scores.

New Possible Surgical Approaches for the Submammary Adipofascial Flap Based on Its Arterial Supply

Introduction. Submammary adipofascial flap (SMAF) is a valuable option for replacement of the inferior portion of the breast. It is particularly useful for reconstruction of partial mastectomy defects. It is also used to cover breast implants. Most surgeons base this flap cranially on the submammary skin crease, reflecting it back onto the breast. The blood vessels supplying this flap are not well defined, and the harvest of the flap may be compromised due to its uncertain vascularity. The aim of the work was to identify perforator vessels supplying SMAF and define their origin, site, diameter, and length. Materials and Methods. The flap was designed and dissected on both sides in 10 female cadavers. SMAF outline was 10 cm in length and 7 cm in width. The flap was raised carefully from below upwards to identify the perforator vessels supplying it from all directions. These vessels were counted and the following measurements were taken using Vernier caliper: diameter, total length, length inside the flap, and distance below the submammary skin crease. Conclusions. The perforators at the lateral part of the flap took origin from the lateral thoracic, thoracodorsal, and intercostal vessels. They were significantly larger, longer, and of multiple origins than those on the medial part of the flap and this suggests that laterally based flaps will have better blood supply, better viability, and more promising prognosis. Both approaches, medially based and laterally based SMAF, carry a better prognosis and lesser chance for future fat necrosis than the classical cranially based flap.
