Surgical treatment of severe or moderate axillary burn scar contracture with transverse island scapular flap and expanded transverse island scapular flap in adult and pediatric patients—A clinical experience of 15 cases

Reconstruction of a septic femoral triangle fistula with a pedicled DIEP flap: A case report and mini-review

Flap-based reconstruction techniques have shown promise in preventing scar contractures and enhancing healing in fold areas by providing vascularized and thick tissue. We report a septic rupture of the superficial femoral artery treated with an arterial allograft and covered with a contralateral pedicled Deep Inferior Epigastric Artery Perforator (DIEP) flap. The patient presented favorable outcomes, including optimal healing at 8 months, with no functional limitation. A literature review also discusses alternative pedicled perforator flaps. These modern techniques present several advantages, including reliability, and can be of great interest in complex vascular surgery cases.

Management of Severe Extended Burn Axillary Contracture in a Low-resource Setting

Contracture is a common complication of deep burn injury, affecting up to one-third of patients. Although some degree of contracture occurs in any setting, severe extended axillary contractures are more often due to unavailable or inappropriate care. Very few cases have been described in the literature. Their management can be especially challenging in a low-resource environment. The purpose of this article is to present two cases in which severe postburn axillary contractures were effectively managed in a low resource setting, using an island perforator flap coupled with a skin graft or advancement flap. In severe extended axillary contracture, more than one technique is often required to cover the large defect created after contracture release.

Reconstruction of Axillary Defect due to Necrotizing Fasciitis and Debridement Using a Free-Flap Transfer: A Report of Three Cases

Background Necrotizing fasciitis is a well-known disease that causes extensive tissue infection and requires radical debridement of the infected tissue. It can occur in all parts of the body, but there are few reports of necrotizing fasciitis in the axilla. We treated three patients with axillary necrotizing fasciitis.

Methods In all cases, patients were referred to us after radical debridement of the infected soft tissue in the emergency department. At the first visit to our department, there were fist-sized soft tissue defects in the axilla. Moreover, the ipsilateral pectoralis major and latissimus dorsi muscles were partially resected because of the debridement of necrotizing fasciitis. In all cases, the ipsilateral thoracodorsal vessels were severely damaged and free-flap transfer was performed to close the axillary wound.

Results All free flaps survived without complications. The patient's range of motion for shoulder abduction on the affected side was maintained postoperatively.

Conclusion If necrotizing fasciitis occurs in the axilla, tissue infection can spread beyond it. In such a case, free-flap transfer can be an optimal treatment. Radical resection of the infected tissue results in the absence of recipient vessels in the axilla. Surgeons should bear in mind that, because of radical resection of the infected tissue, they may need to seek recipient vessels for free-flap transfer far from the axilla.

Effects of multiple modes of UltraPulse fractional CO2 laser treatment on extensive scarring: a retrospective study

The main therapeutic options for extensive scarring (e.g., > 20% of the total body surface area, or TBSA) after burns and trauma have focused on conservative treatments, such as compression, moisturization, and topical agent application. However, these treatments may not achieve optimal effects due to the large size and complexity of the scars. UltraPulse fractional CO₂ laser treatment is a novel approach that is currently a subject of intense interest; this treatment is most widely used to improve texture, pliability, and pigmentation in all types of scars. However, no studies on the independent use of UltraPulse fractional CO₂ laser treatment for extensive scars have been reported. This retrospective study evaluated a total of 21 patients, whose scars covered 20 to 65% TBSA. Scar thickness was measured by ultrasonography before treatment. Personalized treatment modalities and parameters were set according to the scar type and thickness. Scar formation and treatment effects were evaluated by photography, the Patient and Observer Scar Assessment Scale (POSAS), and patients’ judgment of effectiveness. Where the scars covered joints, joint function was assessed by measuring the maximum range of motion (ROM). With laser therapy, scars became flatter and lighter; furthermore, pruritus, pain, and discomfort decreased significantly. POSAS scores significantly decreased after laser therapy, including the item scores for pain and pruritus. There were no instances of joint contracture, ROM reduction, apparent functional impairment, serious adverse events, or comorbidities. This study demonstrates the safety and efficiency of UltraPulse fractional CO₂ laser treatment for extensive scarring.

Coverage losses of substance in the shoulder

Losses of substance of the shoulder are less common than elsewhere in the upper limb. They arise essentially from tumors (sarcomas), infectious diseases (hidradenitis) or traumatic events, (burns). The objectives of reconstruction depend on whether the losses of substance are located on the curve of the shoulder or in the axillary area. There exist numerous regional solutions, including perforator, propeller, pedicled and free flaps. The donor region may be the thorax (latissimus dorsi, serratus anterior), the back (trapezium, scapular or subscapular flaps, occipito-cervico-thoracic flap), the anterior surface of the thorax (pectoralis major or minor, supraclavicular, perforators of the acromiothoracic artery, delto-pectoral flap) or arm (brachial lateral or medial). Multitissular reconstructions are also possible in regional and pedicled form, as well as microanastomosed flaps in exceptional conditions.

Anatomic Study and Clinic Application of Transverse Circumflex Scapular Artery Perforator Flap Repair of Lower Limb Soft Tissue Defects in Children

PURPOSE

The aim of this study was to demonstrate the viability of the transverse circumflex scapular artery perforator flap (TCSAPF) in children with soft tissue defects of the lower limb.

METHODS

In an anatomic study, 25 fresh cadavers were injected with lead oxide-gelatin for spiral computed tomography and 3-dimensional image reconstruction. In a 3-year clinical application study, children with soft tissue defects and exposed tendons and/or bones in the lower limb underwent free-TCSAPF repair of the defect.

RESULTS

Perforators from the transverse branch of the circumflex scapular artery were identified in both anatomical and clinical studies. The average external diameter was 0.9 ± 0.3 mm. Each perforator supplied an average area of 63.5 ± 16.8 cm in anatomical. Twenty-one children were included in this group (9 boys, 12 girls, mean age, 6.6 ± 2.7 years). The size of the flaps ranged from 6 to 17 cm × 4.5 to 7 cm (average, 65.3 ± 22.6 cm). The average flap harvesting time was 30.1 ± 8.5 minutes, average operation time was 138.6 ± 31.5 minutes, and average blood loss was 89.5 ± 21.9 mL. The average length of the vessel pedicle was 8.2 ± 2.4 cm. Arterial congestion occurred in one child, 18 hours postoperatively; subsequent re-exploration and great saphenous vein transplantation were successful. Of the 3 children who had bulky flaps, 1 patient underwent defatting. Satisfactory outcomes included good appearance and function of the recipient and donor areas.

CONCLUSIONS

The TCSAPF provides high-quality skin and vessel flexibility, providing a reliable blood supply in children. The flap has potential benefits over existing perforator flaps.

Statistical analysis of factors affecting re-operative times in paediatric patients with scar deformity after deep second-degree burn injury

Deep second-degree burn injuries pose a challenge for treating scar deformity in developing paediatric patients. Some patients underwent several re-operations during their development. There was no literature reporting which factors affect re-operative times. In this article, we intend to analyse possible influential factors that are responsible for re-operative times in paediatric patients with scar deformity after deep second-degree burn injuries. From 2010 to 2016, 177 paediatric cases with a history of deep second-degree burn injury who underwent re-operation once, twice, and equal to or more than thrice were recruited to this study, with age ranging from 0 to 18 years. The following factors were analysed: age, gender, size of scar, method for reconstruction, location, postoperative anti-scar treatment, preschool group, school group, combined deformity, and combined method for reconstruction. One-way ANOVA and multi-way ANOVA analysis were used as statistical tools to analyse the above factors and re-operative times. There were 83 male cases and 94 female cases, with an average age of 7.47 years. Statistical significance was achieved for the size of scar (P = 0.000), operation method (P = 0.001), and combined deformity (P = 0.026) under 1-way ANOVA in different re-operative times. The operation methods for the head and neck area (P < 0.05) and the lower extremities (P < 0.05) are critical factors for multi-factor variance analysis in different re-operative times. Multivariate logistic regression analysis also demonstrated that the size of scar was an independent risk factor for the number of operations. Combined operative method was a protective risk factor for the number of operations. There was no statistical significance obtained for other factors. Size of scar, operation method, and combined operation method are the risk factors for re-operative times, while operation methods for the head and neck area and lower extremities are the critical factors for re-operative times. We can use the combined method to resolve scar-related problems in order to reduce re-operative times.
