Background Hidradenitis suppurativa (HS) is a chronic skin pathology characterized by the occurrence of inflamed and swollen lesions, with a devastating impact of the disease on patient's quality of life. Wide local excision (WLE) of the affected tissue is the criterion-standard treatment, but there is no general consensus on the best reconstructive technique. The aim of this article is to evaluate the quality of life before and after WLE combined with pedicled perforator flap reconstruction, in patients suffering from HS. Methods We analyzed 26 consecutive patients suffering from Hurley stage III HS. Every patient underwent WLE, followed by reconstruction with pedicled perforator flap. Dermatology Quality of Life Index (DLQI) tests were administered to every patient preoperatively and 6 months after surgery, when the clinical condition was considered stable. Dermatology Quality of Life Index scores were compared in terms of means with Student t test. Linear regression studies were used to compare the changes in DLQI score with the surgical and clinical variables. Results Axillary area involvement was found in 21 of 27 patients; 6 patients had more than 1 body region involved. Thirty-two pedicled perforator flaps were performed, and 22 were thoracodorsal artery perforator flaps. Mean DLQI test score before the first operation was 21.31 ± 4.79; the average DLQI score after the last follow-up was 5 ± 2.95 (P < 0.0001). Dermatology Quality of Life Index scores were not influenced by complications including reoperation. There were also no correlations found between DLQI score delta and number of reoperation (−0.18) or days of hospital stay (−0.13). Conclusions Wide local excision followed by pedicled perforator flap reconstruction allows a radical excision of HS areas with short postoperative healing periods. Dermatology Quality of Life Index scores confirmed high levels of patients' satisfaction. Disadvantages of this technique include difficult learning curve, long operating time, and a nonnegligible complications rate.

MGA free flaps are a versatile option for upper and lower extremity osseous reconstruction, offering high rates of union with minimal complications for a complex patient population. This study furthers our understanding of patient outcomes following MGA flap reconstruction, which previously was limited to case reports and small case series.

The best known limitation to the use of prefabricated flaps is their limited survival area. One explanation for this is insufficient neovascularization. However, blood flow of prefabricated flaps is through their innate vascular network. This could lead one to conclude that angiosomes may impede blood perfusion. This study aims to settle this contradiction between theory and clinical practice. We performed a two-stage operation of a prefabricated abdominal flap in a rat model. The rats were divided into five groups ( = 6/group). Group A: fixed pedicle at a horizontal angle; Group B: fixed pedicle at an oblique angle; Group C: fixed pedicle at a vertical angle; Group D: fixed pedicle in the same position as Group A; and Group E: axial flap. Groups A and B were prefabricated for 2 weeks and Groups C and D were prefabricated for 3 weeks. Macroscopic appearance was noted, and analysis of near-infrared fluorescence imaging and capillary density was performed. There was no significant difference in the flaps' survival area between Groups A and B. Group D had a significantly larger survival area when compared with Group C. The boundary between two angiosomes (medioventral line) seemed to limit the indocyanine green perfusion in Groups B, C, and E, while in Groups A and D, no such limitation was seen. Capillary density was positively correlated with neovascularization time. Angiosomes impede blood perfusion in prefabricated flaps. Cross-bound neovascular vessels nourish the flap, thus overcoming the limitation of choke vessels.
