Abstract Introduction Necrotizing soft tissue infections (NSTIs) are some of the more difficult disease processes encountered by physicians. Most patients require multiple surgical debridements, and survivors often have complex wounds requiring soft tissue coverage and prolonged hospitalizations. The goal of this report is to describe the use of autologous skin cell suspension over widely meshed skin graft in a patient with large wound secondary to a NSTI. Methods A retrospective chart review was performed of a patient with NSTI of the abdomen.The patient received autologous skin cell suspension as an epidermal graft in combination with widely meshed skin grafting. Results A 41 year-old female had an abdominal wound infection resulting in a NSTI. The patients had poorly controlled diabetes, congestive heart failure, and coronary heart disease with a drug eluting stent on dual antiplatelet therapy. She presented septic to an outside facility where she underwent multiple abdominal wound debridements. She was transferred to our institution with concerns for ongoing infection. Upon arrival, the wounds appeared stable with granulation tissue present over the wound bed with small areas of necrotic fat. She underwent debridement and autologous skin cell suspension in combination with a widely (3:1) meshed skin graft. The donor site also received treatment with the cell suspension. The wounds were covered with a non-adherent dressing along with bismuth-impregnated, petroleum-based gauze. Additional padding was secured with sutures to prevent post-operative shearing. On post-operative day (POD) 2 the outer dressings were changed with excellent adherence of the graft. On POD 4 her dressings were taken down completely, staples were removed, and she was transitioned to daily topical antimicrobial ointment and a non-adherent dress to her torso. She had >95% closure on POD 7 on both her graft and donor site. Conclusions Similar to severe burn injuries, the magnitude and scope of NSTI necessitates radical debridement often creating challenges in wound care, preservation of function, and cosmesis. Autologous skin cell suspension in combination with widely meshed skin grafts appear to be well-suited for treatment of large wounds resulting from NSTI. Treatment of this patient demonstrated decreased healing times, decreased donor sites, and an acceptable cosmetic outcome. Applicability of Research to Practice Autologous skin cell suspension has been approved for the use in partial and full thickness burn either as an epidermal graft alone or in combination with widely meshed grafts. This case report represents an example of its use in large complex wounds secondary to NSTI with acceptable outcomes.

Abstract Introduction Complex wounds (CW) resulting from necrotizing soft tissue infections (NSTIs) and soft tissue traumatic injuries create unique challenges. Radical debridement is often the first step in management but can result in disfigurement with impaired function and compromised cosmesis. The standard of care at our institution for full-thickness burn injuries of similar complexity is widely meshed autografting with application of autologous skin cell suspension (ASCS). Our study is a case series reviewing outcomes using ASCS for CW from non-burn etiology. Methods A retrospective chart review from March 2019 through July 2020 was performed to evaluate the effectiveness of ASCS and widely meshed autografting in CW. Patients presenting with CW underwent serial excisions of devitalized tissue by acute care and burn surgeons. Dermal substitute utilization for wound preparation was at the discretion of the surgeon. Definitive wound closure was achieved using ASCS in combination with a widely meshed autograft. The wounds were covered with a non-adherent, non-absorbent, small pore primary dressing along with bismuth-impregnated, petroleum-based gauze or negative pressure wound therapy dependent on wound bed contour. Further padding with gauze was applied along with compressive dressing. Results In total, 8 patients with CW were included in this review. The mean age was 58 years (range 27-85) with an equal number of males and females. Wound etiology included NSTI (n=5), degloving injury (n=2), and traumatic amputation (n=1). The average wound size measured 1,300cm2 (range 300-3,000). 50% of the patients were treated with a dermal substitute and negative pressure wound therapy prior to ASCS and autograft placement. 7 of 8 patients received split-thickness skin grafting in the ratio of 3:1 with one patient grafted at a 2:1 expansion. 7 of the 8 patients had >90% wound closure within 8-10 days of ASCS and autograft application. One patient had significant graft failure after removing surgical dressings and autograft in the early post-operative period secondary to dementia. One patient expired during the follow-up period secondary to medical comorbidities. The 6 remaining patients had durable wound closure and acceptable cosmetic outcome. All patients were discharged within 10 days of ASCS application with 4 patients discharging home and 4 patients discharging to an acute inpatient rehabilitation. Conclusions This study is the first case series to review ASCS in combination with widely meshed skin grafts in the management of CW from a non-burn etiology. Durable, timely wound closure and an acceptable cosmetic outcome was achieved in these often-challenging CW.

Abstract Introduction An autologous skin cell suspension (ASCS) spray containing keratinocytes, fibroblasts, and melanocytes can be processed from a small split thickness skin sample for use at the point-of-care in the operating room. ASCS have been shown to facilitate epidermal regeneration in large TBSA partial thickness burns with minimal donor site morbidity. We hypothesized that ASCS in conjunction with a 3:1 split thickness skin graft applied to burn wounds and ASCS alone applied to the donor site would facilitate healing in a 95 year-old burn patient with 12% TBSA deep partial and full thickness scald burns to the abdomen and bilateral thighs. To our knowledge, she is the oldest patient to undergo epidermal autografting with ASCS. Methods All burn wounds were tangentially excised in the standard fashion to healthy tissue. Split thickness (12/1000 inch) skin graft was harvested from the right lateral thigh, meshed 3:1, and applied to all wound beds. ASCS were prepared and sprayed on grafted sites and the donor site. All areas were dressed with Telfa clear and Xeroform with bacitracin. Dressings were initially changed every 2 days, and wounds were photographed on day 2, 4, 6, 8, 10, and 20. Results All burn wounds were deep partial thickness or full thickness. The right thigh donor site was completely healed by POD 10. 90% of the burn wounds had healed by POD 10. The area of deepest burn, an approximately 20 cm2area on the left medial thigh, was healed by POD 20. Conclusions We believe that ASCS enhanced the rate of re-epithelialization of burn wounds in a 95 year-old patient compared to our experience with skin grafting alone in this population. ASCS also promoted complete healing of the donor site by POD 10. This technology may have a role in decreasing healing time in the geriatric burn population. These findings are important for this population as longer lengths of stay are associated with delirium, hospital acquired infections, and deconditioning. This patient’s improved donor site healing also has broader implications as split thickness skin grafts are used widely for wound coverage in plastic surgery. Applicability of Research to Practice Demonstrates efficacy of ASCS in very elderly patients with moderate-sized deep burns and with skin graft donor sites.

Background: Reverse-flow posterior interosseous artery (rPIA) flap is an excellent tool for restoration of defects in the hand and upper extremity, sparing the main arteries to the hand. Its reliability has been well established. Materials and Methods: Fifty-one cases of rPIA flap involving 49 patients were retrospectively reviewed. The inclusion criteria were age, sex, etiology, size and location of the defect, flap size, number of perforators included, pedicle length, flap inset, donor site coverage, complications, and ancillary procedures. Results: This study included 44 men and 5 women, ranging in age between 10 and 73 years. The subjects had soft tissue defects of the hand and upper extremity mainly due to traumatic injuries, including scar contractures of the first web space in 18 cases, thumb amputations in 6 cases, and congenital defects in 1 case. Among the 51 rPIA flap elevations, 3 cases involved flap failure due to the absence of proper pedicle. A fasciocutaneous pattern was observed in 45 cases and a myocutaneous pattern in 3 cases. In 5 cases of unplantable thumb amputations, the rPIA flap was performed for arterial inflow to the secondary toe-to-thumb transfer. Venous congestion of varying degrees was noted in 7 cases involving partial necrosis in 2 cases. During the mean 17 months of follow-up, patients were generally satisfied with the final outcomes. Conclusion: The rPIA flap can be used not only for soft tissue coverage of the hand and upper extremity but also as a recipient arterial pedicle for a secondary toe-to thumb transfer.

Introduction: Skin graft reconstruction is a common method of providing wound coverage. Rarely, skin grafting can be associated with the development of squamous cell carcinoma (SCC) in the graft donor site. Case Report: The patient is a 72-year old male with a 15-year history of bilateral hip wounds. He underwent a multitude of treatments previously with failed reconstructive efforts. After presenting to us, he underwent multiple debridements and eventual skin grafting. Within 4 weeks of the final skin graft, a mass developed at the skin graft donor site at the right thigh. Excisional biopsy returned a well differentiated keratinizing SCC. Discussion/Conclusion: This case demonstrates the acute presentation of SCC in a patient following a skin graft without known risk factors. The purpose of this unique case report is to highlight a very rare occurrence of SCC at a skin graft donor site.

Background: In recent years, the composite anterolateral thigh free flap with tensor fasciae latae or vastus lateralis has been a new-applied type of flap that can provide very good reconstruction materials in complex defects of lower leg and foot. The study purpose is to evaluate the systematically complications of donor site, related factors to results of the donor area, in order to apply the result to improve the treatment, which have not been much reported in literature. Materials and Methods: Systematic donor site morbilidy evaluation in a prospective, uncontrolled clinical descriptive study of 33 composite anterolateral thigh free flaps in various forms to reconstruct anatomical structures or to resconstruct deep defects combined with covering the surfaces for complex soft tissue defects in lower extremities for 32 patients due to different causes in lower leg and foot area from 2014-2019 at Hue University of Medicine and Pharmacy. Examining and evaluating aesthetic and functional result of donor-site 3 months and 6 months up to 2 year after surgery; evaluating the correlation between the width and the type of the flaps and donor site closure methods. Result: In 33 composite flaps used, flap width to thigh circumference less than 20% in 27 cases (81.8%), more than 20% in 6 cases (18.20% ); There were 28 cases in which the donor site was directly closed, 5 cases required skin graft; All direct closed cases had flap width/ thigh circumference index below 20%; On the contrary, in cases having this index greater than 20%, the donor site required skin graft with p < 0.01. There are 11/33 (33.33%) of cases reported complications in donor site ; lateral thigh paresthesia is the most complicated complication with 8/33 cases (24.24%), followed by bad scarring 3/33 cases (9.09%). Conclusion: Long term follow up donor site morbility after composite anterior thigh free flap present 11/33 cases (33.33%): mostly complications of the donor site are thigh paresthesia with 8/33 cases (24.24%), and bad scarring 3/33 cases (9,09%), which improve time by time.

Microsurgical Reconstruction

AbstractReconstruction of bony and soft tissue defects of the lower extremity has been revolutionized by the advent of microsurgical tissue transfer. There are numerous options for reconstruction. Possibilities include transfer of soft tissue, composite (bone and soft tissue) tissue, and functional muscle. Many lower extremity reconstructions require staged procedures. Planning is of paramount importance especially in regard to vascular access when multiple free flaps are required. Soft tissue reconstruction of the lower extremity may be accomplished with muscle flaps such as the rectus femoris and latissimus dorsi covered with a skin graft. Fasciocutaneous flaps such as the anterolateral thigh flap may be more appropriate in a staged reconstruction which requires later elevation of the flap. Loss of a significant portion of bone, such as the tibia, can be difficult to manage. Any gap greater than 6 cm is considered a reasonable indication for vascularized bone transfer. The contralateral free fibula is the donor site of choice. Functional reconstruction of the anterior compartment of the leg may be performed with a gracilis muscle transfer, effectively eliminating foot drop and providing soft tissue coverage. Muscle tensioning is critical for effective excursion and dorsiflexion of the foot. Long-term results of microsurgical reconstruction of the lower extremity show good results and reasonable rates of limb salvage.

Abstract Introduction Treatment of large TBSA burn injuries is often limited by donor site availability and requires reharvesting to obtain definitive closure. Patients with severe injuries may have delayed closure compared to uncompromised patients that typically have their donor sites healed in 7–14 days. Autologous skin cell suspension (ASCS) can be prepared to treat burn wounds at the point-of-care. The safety and effectiveness have not yet been established for use in the treatment of donor sites. This study presents the use of ASCS for the treatment of donor sites in patients with life-threatening burn injuries that were enrolled in a prospective uncontrolled observational study (IDE 15945—NCT02992249). Methods ASCS was applied to the donor site after harvesting of STSGs. Clinical outcomes out to one year were evaluated including percentage of re-epithelialization, long-term cosmetic outcomes, and adverse events. Results Ninety-six subjects from 22 burn centers had their donor sites treated with ASCS as part of their treatment regimen. The average subject age was 30.1 and the average TBSA injury was 53.7 ±17.3%. The mean Baux score was 89.2 with 36% of subjects having a score greater than 100. Collectively, 528 donor sites were individually treated. In this compromised patient population 37.5% were ≥95% re-epithelialized by week 1 (n=435), and by week 2, 82.7% of the donor sites were ≥95% re-epithelialized (n=434), regardless of how many times they were harvested. Approximately 19% of the donor sites treated with ACSC were reharvested multiple times following initial healing (15% two times, 2.3% three times, and 7 donor sites were harvested 4 times) and retreated. Of donor sites harvested more than once, 39.3% (n=84), 81% (n=79), and 85.7% (n=77) of sites were ≥ 95% re-epithelialized by week 1, 2 and 4, respectively. One-year data was available for 427 donor sites and the majority had matched or mildly mismatched color, pigment, and texture. Adverse events included one site with a hematoma, one patient with donor sites that had fragile skin loss secondary to traumatic friction, one patient with active bleeding, two patients with anemia secondary to donor site bleeding, one patient with delayed closure due to mild infection of staph species. All AEs were unlikely or unrelated to the device. Conclusions ASCS has been successfully used to achieve closure of donor site wounds without significant safety risk in patients with extensive burn injuries. Applicability of Research to Practice Application of ASCS for donor site healing may be particularly relevant for patients with large burn injuries requiring subsequent reharvesting to achieve definitive closure.
