The concept of "whole perforator system" in the lateral thoracic region for latissimus dorsi muscle-preserving large flaps: An anatomical study and case series

Scarless Donor Site for Breast Reconstruction by Endoscopically Assisted Extended Latissimus Dorsi Flap plus Lipofilling

BACKGROUND

Breast reconstruction using endoscopically assisted latissimus dorsi (LD) flap leaves no scar on the back; however, the small amount of tissue obtained makes this procedure less practical. This study aimed to propose a new technique of endoscopically assisted extended LD (eeLD) flap plus lipofilling, which could secure a large breast volume.

METHODS

Lateral thoracic adipose tissues supplied by the thoracodorsal artery branches and the LD muscle were elevated as a single unit only through the mastectomy scar and three ports through the lateral chest. Furthermore, fat was simultaneously injected to support the volume and shape of the breast. Changes in the volume of the reconstructed breast over time were measured using three-dimensional stereophotogrammetry.

RESULTS

Overall, 15 breasts of 14 patients who underwent breast reconstruction using an eeLD flap exhibited no serious complications. On average, 281.9 ± 32.4 g of flap and 74.7 ± 19.4 mL of lipofilling were used. Within 8 weeks after the procedure, the volume of the reconstructed breast decreased to 69.5 ± 7.5% and then plateaued. Seven patients needed a subsequent session of lipofilling to acquire adequate breast volume and projection. Notably, according to the BREAST-Q back scores, patients who underwent eeLD flap surgery were significantly more satisfied than those who underwent conventional LD musculocutaneous flap surgery using a skin paddle on the back at the same institution (82.8 ± 9.2 versus 62.6 ± 6.3; P < 0.0001).

CONCLUSION

Despite the limitations in volume, eeLD flap plus lipofilling is advantageous because it does not leave a noticeable donor-site scar.

Revisiting the pedicled circumflex scapular artery (pCSA) perforator flap: From simple to complex locoregional reconstructions

BACKGROUND

Soft tissue defects involving the axilla and the upper back region are often complex to treat. The complexity of these defects may be extremely different, ranging from superficial skin damage to large loss of substance with lymphatic drainage impairment. The pedicled circumflex scapular artery (pCSA) perforator flap represents a valid procedure in this setting. It can be tailored according to the patient's needs, and its intraseptal pedicle allows a quick dissection with a wide range of motion.

PATIENTS AND METHODS

Twenty-four consecutive patients treated by means of pCSA perforator flap were included. All the flaps were pedicled and were used for locoregional reconstructions. The etiology of the defects was an oncologic resection in 15 cases, acne/hidradenitis suppurativa resection in 6 cases, lymphatic complication in 2 cases, and burn in 1 case. Patients' mean age was 61 years old; seventeen were males and seven were females.

RESULTS

All the patients were successfully treated with good aesthetic and functional results. One patient presented with a wound dehiscence, which required secondary surgical treatment. No partial or complete flap losses were encountered. Primary closure of the donor site was achieved in all cases. The mean follow-up period was 10.5 months (range 6-12).

CONCLUSIONS

This case series shows the reliability and versatility of the pCSA perforator flap for locoregional reconstructions. Because of its rich vascularisation, extensive or unconventionally-shaped flaps are possible. Moreover, its lymphatic rich tissues make it suitable for the treatment of complications related to axillary lymphadenectomy.

Pedicled circumflex scapular artery perforator flap with intra-axillary tunneling for axillary defect coverage after surgical excision of hidradenitis suppurativa: A case report and literature review

Axillary defects represent a rather common issue in plastic surgery practice. Surgical resections related to skin disease are frequent in this region and their extension often requires soft tissue transfer for coverage. In this setting, locoregional pedicled flaps are usually preferred. The nearby tissues offer pliable but still resistant skin, which satisfy the "like-with-like" reconstructive principle. Over the years different procedures have been described for this purpose. Among them, a valuable and often underestimated technique is the circumflex scapular artery perforator flap (CSAP). This technique might be particularly suitable for thin but relatively large defects. Its main advantages are a low donor site morbidity, a very reliable anatomy, and a perforator pedicle able supply a large skin paddle. In the present work, we report the use of a pedicled vertical CSAP flap passed through the axillary canal in order to cover a 9 cm × 7 cm axillary defect after surgical excision of hidradenitis suppurativa resistant to conservative treatment. The perforator-based pedicled presented two branches, which allowed us to harvest safely a large skin paddle, which limited its range of motion. For this reason, we opted for a passage through the axillary canal for the flap inset. The postoperative course was uneventful and full shoulder range of motion was obtained at 3 months follow-up. Despite most of the descriptions of this flap available so far showed its employment for limb's reconstructions, we believe that it is a very useful tool also for locoregional coverage. Moreover, the unconventional passage below the axillary muscles allowed reaching the recipient site even with a shorter pedicle, such as the one encountered in this case.
