Superficial inferior epigastric artery (SIEA) free flap using perforator vessels as a recipient site: clinical implications in autologous breast reconstruction.

BACKGROUND: Breast reconstruction with autogenous tissue is a well-established technique, but there are some limitations related to donor-site morbidity. Among available techniques, the superficial inferior epigastric artery (SIEA) flap is the least invasive procedure because it does not require harvesting or incision of the rectus muscle or the abdominal fascia. Besides adequate flap choice, the proper selection of the recipient vessels is an important factor. Thus, the internal mammary perforator branches (IMPBs) have been an attractive option regarding recipient pedicle morbidity. METHODS: The investigators reported the use of the free SIEA flap with the IMPBs as a recipient site to reconstruct radical mastectomy. RESULTS: Five patients with invasive ductal carcinoma underwent modified radical mastectomy and reconstruction. The IMPBs were selected as the recipient site and a free SIEA flap was used. The donor defect was closed directly without synthetic mesh. Satisfactory breast shape was achieved, and no complications were observed. CONCLUSIONS: For selected patients, the SIEA flap and IMPBs may constitute a new alternative for immediate breast reconstruction, because of the possibility of large tissue transfer with minimal donor and recipient area morbidity. The SIEA pedicle size and the quality of IMPB vessels should be carefully evaluated.

Assessment of immediate conservative breast surgery reconstruction: a classification system of defects revisited and an algorithm for selecting the appropriate technique.

BACKGROUND: Although various techniques have been used for breast conservation surgery reconstruction, there are few studies describing a logical approach to reconstruction of these defects. The objectives of this study were to establish a classification system for partial breast defects and to develop a reconstructive algorithm. METHODS: The authors reviewed a 7-year experience with 209 immediate breast conservation surgery reconstructions. Mean follow-up was 31 months. Type I defects include tissue resection in smaller breasts (bra size A/B), including type IA, which involves minimal defects that do not cause distortion; type IB, which involves moderate defects that cause moderate distortion; and type IC, which involves large defects that cause significant deformities. Type II includes tissue resection in medium-sized breasts with or without ptosis (bra size C), and type III includes tissue resection in large breasts with ptosis (bra size D). RESULTS: Eighteen percent of patients presented type I, where a lateral thoracodorsal flap and a latissimus dorsi flap were performed in 68 percent. Forty-five percent presented type II defects, where bilateral mastopexy was performed in 52 percent. Thirty-seven percent of patients presented type III distortion, where bilateral reduction mammaplasty was performed in 67 percent. Thirty-five percent of patients presented complications, and most were minor. CONCLUSIONS: An algorithm based on breast size in relation to tumor location and extension of resection can be followed to determine the best approach to reconstruction. The authors' results have demonstrated that the complications were similar to those in other clinical series. Success depends on patient selection, coordinated planning with the oncologic surgeon, and careful intraoperative management.
