Utilizing Low-cost Vacuum-assisted Closure as Adjuvant Therapy in Soft Tissue Reconstruction for a Mangled Upper Extremity. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2024; 12:e5826. [PMID: 38798936 PMCID: PMC11124598 DOI: 10.1097/gox.0000000000005826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 03/25/2024] [Indexed: 05/29/2024]
Abstract
Soft tissue reconstruction using flaps in managing mangled injuries is occasionally insufficient due to large defects and low flap viability. Conversely, delaying the closure of the defect can elevate the risk of infection. Adjuvant therapy becomes essential in the management of mangled injuries. We aim to present the use of low-cost vacuum-assisted closure (VAC) as an adjuvant therapy for mangled injuries. We reported the case of a 20-year-old man who sustained a mangled injury to his left forearm in a traffic accident 4 hours before admission. The mangled extremity severity score was 9; however, the patient declined amputation. Although the initial reconstruction was done, the flap could only cover vital structures. VAC was utilized to address the uncovered portion of the defect, to promote optimal granulation and prevent infection. The reconstruction proceeded with a skin graft and wrist arthrodesis. At 1-year follow-up, viable tissue was obtained but contracture occurred at the metacarpophalangeal and proximal interphalangeal joints. We intend to perform functional reconstruction at a later stage. Although the benefits of VAC in wound management are well established, reports regarding its advantages in mangled injury management remain relatively scarce. The high cost of VAC is a limiting factor, particularly in developing countries. This prompts the need for an affordable VAC innovation with comparable efficiency to the commercial model. Reverse Aqua Pump VAC, our innovative low-cost VAC, shows satisfactory outcomes in managing patients with mangled injuries with mangled extremity severity score indicating amputation.

[PMID: 37900944 PMCID: PMC10602717 DOI: 10.3389/fphys.2023.1194051] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Accepted: 10/03/2023] [Indexed: 10/31/2023] Open
Abstract
The purpose of this study is to review the research progress of negative pressure wound therapy (NPWT) for scar revision and discuss the prospects of its further study and application. The domestic and foreign literatures on NPWT for scar revision were reviewed. The mechanism and application were summarized. NPWT improves microcirculation and lymphatic flow and stimulates the growth of granulation tissues in addition to draining secretions and necrotic tissue. As a significant clinical therapy in scar revision, NPWT reduces tension, fixes graft, and improves wound bed. In the field of scar revision, NPWT has been increasingly used as an innovative and constantly improving technology.

Park JH, Park JU. Flap monitoring with incisional negative pressure wound therapy (NPWT) in diabetic foot patients. Sci Rep 2022; 12:15684. [PMID: 36127377 PMCID: PMC9489718 DOI: 10.1038/s41598-022-20088-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Accepted: 09/08/2022] [Indexed: 11/24/2022] Open
Abstract
Various types of flaps are considered as reconstructive options for patients with diabetic foot ulcer. However, flap reconstruction for diabetic foot ulcer treatment is particularly challenging because of the relatively limited collateral perfusion in the distal lower extremity. This study evaluated the efficacy and safety of a novel postoperative monitoring procedure implemented in conjunction with negative pressure wound therapy immediately after flap operations for treating diabetic foot. A retrospective analysis was performed on diabetic foot patients who underwent free flaps and perforator flaps from March 2019 through August 2021. The surgical outcomes of interest were the rates of survival and complications. On the third postoperative day, patients underwent computed tomography angiography to check for pedicle compression or fluid collection in the sub-flap plane. Monitoring time, as well as comparisons between NPWT and conventional methods, were analyzed. Statistical analysis was performed between the two groups. This study included 26 patients. Among patients, the negative pressure wound Therapy treated group included 14 flaps and the conventional monitoring group included 12 flaps. There was no significant intergroup difference in flap survival rate (p = 0.83). In addition, there was no significant intergroup difference in the diameters of perforators or anastomosed vessels before and after negative pressure wound therapy (p = 0.97). Compared with conventional monitoring, flap monitoring with incisional negative pressure wound therapy was associated with a significantly lower mean monitoring time per flap up to postoperative day 5. Although conventional monitoring is widely recommended, especially for diabetic foot ulcer management, the novel incisional negative pressure wound therapy investigated in this study enabled effortless serial flap monitoring without increasing complication risks. The novel flap monitoring technique is efficient and safe for diabetic foot patients and is a promising candidate for future recognition as the gold standard for flap monitoring.

Polymers (Basel) 2022; 14:polym14081585. [PMID: 35458338 PMCID: PMC9029864 DOI: 10.3390/polym14081585] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Revised: 03/24/2022] [Accepted: 04/04/2022] [Indexed: 12/19/2022] Open
Abstract
Traditional medical soft matrix used in a surgical treatment or in wound management was not good enough in both the structural support and interconnectivity to be applied in tissue engineering as a scaffold. Avian skeleton and feather rachises might be good reference objects to mimic in designing a scaffold material with good structural support and high interconnectivity because of its structural foam-wall microarchitectures and structural pneumaticity. In this study, a biomimetic airstream pore-foaming process was built up and the corresponding new medical soft matrix derived from polyvinyl alcohol matrix (PVAM) with air cavities inspired by avian skeleton and feather rachises was prepared. Furthermore, the resulting medical soft matrix and bovine Achilles tendon type I collagen could be employed to prepare a new collagen-containing composite matrix. Characterization, thermal stability and cell morphology of the bioinspired PVA matrix and the corresponding collagen-modified PVA composite matrix with open-cell foam-wall microarchitectures were studied for evaluation of potential tissue engineering applications. TGA, DTG, DSC, SEM and FTIR results of new bioinspired PVA matrix were employed to build up the effective system identification approach for biomimetic structure, stability, purity, and safety of target soft matrix. The bioinspired PVA matrix and the corresponding collagen-modified PVA composite matrix would be conductive to human hepatoblastoma HepG2 cell proliferation, migration, and expression which might serve as a promising liver cell culture carrier to be used in the biological artificial liver reactor.
