World J Clin Cases 2023; 11:143-149. [PMID: 36687191 PMCID: PMC9846988 DOI: 10.12998/wjcc.v11.i1.143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 11/01/2022] [Accepted: 12/09/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Thermal injuries on free transferred or replanted tissues resulting from loss of sensibility are an infrequent occurrence. They require immediate and appropriate management before they progress to an irreversible condition. Although negative pressure wound therapy (NPWT) can prevent wound progression by increasing microcirculation, the inappropriate application of NPWT on complication-threatened transferred and replanted tissues can induce an adverse effect.
CASE SUMMARY A 48-year-old woman who underwent immediate breast reconstruction with a deep inferior epigastric artery perforator free flap. While applying a heating pad directly to the flap site, she sustained a deep second to third-degree contact burn over 30% of the transferred flap on postoperative 7 d. As the necrotic changes had progressed, we applied an NPWT dressing over the burned area after en-bloc debridement of the transferred tissues on postoperative 21 d. After 4 d of NPWT application, the exposed fatty tissues of the flap changed to dry and brown-colored necrotic tissues. Upon further debridement, we noted that the wound gradually reached total necrosis with a collapsed vascular pedicle of deep inferior epigastric artery.
CONCLUSION Although NPWT has been shown to be successful for treating various wound types, the significant risk of NPWT application in short-lasting reconstructed flap wounds after thermal injury should be reminded.

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.

Abstract
BACKGROUND Fingertip replantation is technically challenging. Venous congestion is one of the most common causes of replantation failure. Therefore, various venous drainage procedures and salvage techniques have been used in venous congestion. Negative-pressure wound therapy has proven beneficial in limb injuries, yet limited studies of fingertip replantation exist. This study aims to analyze risk factors in fingertip replantation and to evaluate the feasibility and clinical benefits of negative-pressure wound therapy compared with other salvage techniques. METHODS From January of 2015 to December of 2019, 27 patients (27 digits) who experienced fingertip amputation over Tamai zone I or II underwent replantation. Salvage negative-pressure wound therapy was applied for venous congestion postoperatively. Replantation data were collected for further analysis. RESULTS The overall survival rate of digit replantation with salvage negative-pressure wound therapy was 92.6 percent (25 of 27). The blood transfusion rate was 11.1 percent (three of 27). The average hospitalization time was 8.04 ± 1.43 days and the median duration of negative-pressure wound therapy was 6 days (range, 4 to 8 days; interquartile range, 2 days). There is no significant difference between the survival and failure groups for all risk factors evaluated. CONCLUSION Negative-pressure wound therapy is a simple and effective salvage option to relieve venous congestion in fingertip replantation with a satisfactory survival rate, low blood transfusion rate, and short inpatient stay. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
Various types of flaps are widely utilized as reconstructive options for patients with soft tissue defects. However, the postoperative monitoring of the flap requires a large amount of time and effort. The aim of this study was to evaluate the efficacy and safety of this novel monitoring procedure using negative pressure wound therapy (NPWT) immediately after the flap operations.A retrospective analysis was performed on patients who underwent free flaps and perforator flaps from March 2019 to December 2020. The flaps were managed by either novel NPWT method or conventional dressing. Among NPWT group, computed tomography angiography was performed in randomly selected 5 flaps on the third postoperative day for evaluation of pedicle compression. Statistical analysis was performed between the 2 groups.A total of 54 flaps were included in this study. Twenty seven flaps were managed using novel NPWT method and 27 flaps were managed using conventional dressing. There was no statistically significant difference in flap survival rates between the 2 groups (P = .91). The patency of flap pedicles in the NPWT group was confirmed by comparing the computed tomography angiography findings. The estimated total flap monitoring time and cost for 5 days was significantly decreased by the application of the novel NPWT monitoring system.Through the application of the novel postoperative monitoring system using NPWT, there is efficient evaluation of the flap. Furthermore, safe flap monitoring is possible with the reduced risk of infection by the avoidance of multiple manual dressing performed in the conventional method.

Abstract
Negative pressure wound therapy (NPWT) is usually applied in wound management and soft-tissue salvage after the development of complications. However, immediate postoperative application of NPWT over the flap coverage is seldom reported. We evaluate the effectiveness of immediate postoperative application of NPWT following fasciocutaneous or muscle flap coverage for lower leg reconstruction. A retrospective review of patients who underwent either fasciocutaneous or muscle flap coverage of lower leg soft-tissue defects applied with NPWT immediately after surgery was conducted in a level I trauma center. Sixteen patients, with an average age of 51.2 years, were included in the study. Nine patients had trauma-related soft-tissue loss, six had subsequent soft-tissue defects after debridement, and one had burn injury. Two patients had been treated with free anterolateral thigh flaps, 11 with pedicle flaps, and three with muscle flaps. All flaps survived except for those in two patients with venous congestion on postoperative day 1, which needed further debridement and skin grafting. Therefore, the use of immediate incisional NPWT is an alternative for wound care following flap coverage. The U-shaped design allows easy flap observation and temperature check. Furthermore, this method eliminates any concerns of vascular pedicle compression under negative pressure.

Abstract
One of the most important problems encountered in reconstructive surgery is partial or total flap loss, and venous congestion is the most common reason. It should be solved as early as possible. The purpose of this study is to investigate the effects of Negative pressure wound therapy (NPWT) on an ideal congested rabbit skin flap model without any open wound. The current study included 28 female, adult, New Zealand albino rabbits. Animals were divided into four groups according to the duration of NPWT to be applied. An axial pattern ideal congested skin flap was designed on the posterior surface of the ear. After surgical intervention on the right ears, we applied NPWT treatment for 2, 4, 6 and 8 days. The left ears were followed without any treatment. Samples were taken for edema, congestion and neo-angiogenesis examination. There was no significant difference between the NPWT applied group and control group in the 2nd, 4th, 6th, and 8th days for edema and neo-angiogenesis and no differences in the 2nd, 6th, and 8th days for congestion. NPWT group had a higher flap survival rate than the control group but without a significant difference. This study used an ideal congested rabbit skin flap model imitating venous congestion. Our findings illustrate that NPWT treatment does not have a significant effect on the congested skin flap model we utilized where a closed system was created maintaining a skin barrier without a bare surface of the flap. Level of Evidence: Level I, experimental study.

Flap Venous Congestion and Salvage Techniques: A Systematic Literature Review. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3327.

Abstract
Venous congestion is a frequent problem in flap surgery. Other than surgical revision, there are a multitude of procedures in the literature to tackle this problem, but their effectiveness is not clear. Through a systematic review, we aimed to identify and evaluate the different interventions available for managing flap venous congestion. Methods The MEDLINE, PubMed central, Embase, and Cochrane databases were searched. The study selection process was adapted from the PRISMA statement. All English and French original articles describing or comparing a method for managing flap venous congestion were included. For each article, a level of evidence was assigned, as defined by the Oxford Centre for Evidence-based Medicine. Lastly, we specifically analyzed the effectiveness of postoperative non-surgical methods. No formal analysis was performed. Results Through literature searches carried out in various databases, we identified 224 articles. Finally, 72 articles were included. The majority of these studies had a low-level evidence. A total of 17 different methods (7 pre- and intraoperative, and 10 postoperative) were found. Concerning non-surgical methods, the most represented were leeches, local subcutaneous injection of heparin with scarification, venocutaneous catheterization, negative pressure therapy, and hyperbaric oxygen therapy. Conclusions Risks of venous congestion of flaps must always be present in a surgeon's mind, at every stage of flap surgery. Apart from studies on the use of leeches, which have a significant follow-up and large enough patient numbers to support their efficacy, the low-level evidence associated with studies of other methods of venous congestion management does not allow us to draw a scientifically valid conclusion about their effectiveness.

Abstract
Negative pressure wound therapy (NPWT) is a method for treating wound. However, there are no case reports using NPWT for treating congestion after arterialized venous flap. Therefore, this study reported favorable outcomes after using a single-use NPWT system for managing congestion. A 39-year-old man had his index finger caught by a press machine. The finger had a soft tissue defect at the ventral part. An arterialized venous flap taken from the right forearm was transplanted. Perfusion of the flap was favorable, but on postoperative day 5, congestion and the edema of the flap were found. Then, NPWT was initiated. The congestion and edema in the flap were improved without complications such as flap necrosis and wound infection. At 4 months postoperatively, the morphology of the finger was favorable. In this study, NPWT was speculated to force the deeper blood vessels within the flap to dilate with inducing drainage and the simultaneous reduction in excess blood flow to the cortical layer, resulting in the improvement of congestion. Negative pressure wound therapy was used for treating congestion after the transplantation of arterialized venous flap, and the wound was favorably managed.

Abstract
Negative pressure wound therapy (NPWT) consists in applying subatmospheric pressure to a wound that is sealed off by a specially designed dressing and connected by a tube to a suction pump and drainage collection system. Skin defects are extremely common in orthopaedic and trauma surgery. NPWT is valuable across a range of indications. Proven effects include an increase in blood flow, stimulation of angiogenesis, and a decrease in wound surface area. NPWT can be used to treat post-traumatic and surgical wounds, burns, and chronic wounds such as pressure sores and ulcers. The lower frequency of dressing changes with NPWT lightens the staff workload. The French high authority for health (HAS) has issued good practice guidelines for the use of NPWT in specific and limited indications. NPWT has benefited from the introduction of several technological improvements such as silicone interfaces, foam dressings with various densities and pore sizes, and irrigation systems. The result is greater adaptability to each specific situation. Nevertheless, NPWT is not appropriate in every case and cannot replace a necessary surgical procedure. The goal of this work is to review the principles, practical modalities, and indications of NPWT.

Abstract
PURPOSE The aim of this report is to evaluate the utility of negative pressure wound therapy (NPWT) for rescuing flaps with venous congestion not attributable to a mechanical etiology and that cannot be surgically salvaged. PATIENTS AND METHODS A total of 12 patients suffered from partial or total flap congestion after pedicle or free-flap reconstruction was included. All patients underwent NPWT between 3 and 10 days postoperatively. RESULTS All congested flaps survived after the application of NPWT. Nine patients suffered partial flap loss and this was addressed through debridement of the devitalized tissue and primary closure. Three patients required blood transfusions during the course of their management. All patients presented complete coverage of the defects without further problems in the flaps after the treatment. CONCLUSION NPWT may be considered an alternative management strategy for flaps, which has undergone venous congestion not due to a mechanical cause. © 2016 Wiley Periodicals, Inc.

Abstract
OBJECTIVE To report experience with negative pressure wound therapy (NPWT) in 45 consecutive dogs admitted with extensive cutaneous wounds and to determine if NPWT is feasible in veterinary hospital practice. STUDY DESIGN Prospective descriptive study. ANIMALS Dogs (n = 45). METHODS Collected data were organized into 6 categories: patient data, wound data, NPWT data, adjunctive treatments, complications, and final outcome. RESULTS Wounds (53 in 45 dogs) were largely traumatic in origin, and distributed fairly evenly to the trunk, proximal and distal aspects of the limbs. Most wounds (34 dogs, 76%) had no granulation tissue and were treated a mean of 4.2 days after wounding, whereas 11 dogs had granulating wounds that were initially treated a mean of 87 days after wounding. Median NPWT use was 3 days with a mean hospitalization of 7.8 days. Most wounds (33; 62%) were closed surgically after NPWT and were healed by 14 days. The other 18 wounds healed (mean, 21 days) by second intention after hospital discharge. Overall, 96% of the wounds healed; 2 dogs died before definitive closure could be attempted. CONCLUSION NPWT is applicable to a wide variety of canine wounds, is well tolerated, allows for several days between dressing changes, and can used to optimize the wound bed for surgical closure or second intention healing.

Abstract
Lower limb reconstruction with pedicled or free flaps can be commonly compromised by venous insufficiency. This complication often leads to partial/complete flap necrosis and increases the risk of superinfection. Negative-pressure wound therapy (NPWT) is known to increase local blood flow, decrease edema, promote tissue granulation, and reduce the likelihood of soft tissue infection. This study aims to evaluate the effectiveness of NPWT in the treatment of congested pedicled and free flaps of the lower limb after reconstructions in lower limb traumas. A retrospective analysis was performed on four congested (pedicled and free) flaps on the lower limbs. NPWT was applied in all cases after partial flap debridement. NPWT was able to improve and resolve tissue edema and venous insufficiency, avoid further flap necrosis, and promote granulation. On NPWT removal, a split-thickness skin graft was applied on the wound, achieving complete and uneventful healing. NPWT is a useful instrument in managing flaps affected by venous insufficiency in lower limb reconstruction, although larger studies are necessary to better define the effectiveness and indications of NPWT in this setting.

Abstract
OBJECTIVE To compare healing of free, full-thickness, meshed skin grafts under negative pressure wound therapy (NPWT) with bolster dressings in dogs. STUDY DESIGN Randomized, controlled experimental study, paired design. ANIMALS Dogs (n = 5) METHODS: Full-thickness skin wounds (4 cm × 1.5 cm) were created bilaterally on the antebrachia of 5 dogs (n = 10). Excised skin was grafted to the contralateral limb. Grafts were randomized to NPWT or bolster dressings (control; CON). NPWT was applied continuously for 7 days. Grafts were evaluated on Days 2, 4, 7, 10, 14, and 17, biopsied on days 0, 4, 7, and 14, and had microbial culture on Day 7. Outcome variables were: time to first appearance of granulation tissue, percent graft necrosis, and percent open mesh. Significance was set at P < .05. Histologic findings, culture results, and graft appearance were reported. RESULTS Granulation tissue appeared earlier in the NPWT grafts compared with CON grafts. Percent graft necrosis and remaining open mesh area were both greater in CON grafts compared with NPWT grafts at most time points. Histologic results showed no significant difference in all variables measured, and all cultures were negative. CONCLUSIONS Variables of graft acceptance were superior when NPWT was used in the first week post-grafting. Fibroplasia was enhanced, open meshes closed more rapidly and less graft necrosis occurred with NPWT application. More preclinical studies are required to evaluate histologic differences.

Abstract
Negative pressure wound therapy (NPWT) has become widely adopted over the last 15 years and over 1000 peer reviewed publications are available describing its use. Despite this, there remains uncertainty regarding several aspects of usage. In order to respond to this gap a global expert panel was convened to develop evidence-based recommendations describing the use of NPWT. In this paper the results of the study of evidence in traumatic wounds (including soft tissue defects, open fractures and burns) and reconstructive procedures (including flaps and grafts) are reported. Evidence-based recommendations were obtained by a systematic review of the literature, grading of evidence, drafting of the recommendations by a global expert panel, followed by a formal consultative consensus development program in which 422 independent healthcare professionals were able to agree or disagree with the recommendations. The criteria for agreement were set at 80% approval. Evidence and recommendations were graded according to the SIGN (Scottish Intercollegiate Guidelines Network) classification system. Twelve recommendations were developed in total; 4 for soft tissue trauma and open fracture injuries, 1 for burn injuries, 3 for flaps and 4 for skin grafts. The present evidence base is strongest for the use of NPWT on skin grafts and weakest as a primary treatment for burns. In the consultative process, 11/12 of the proposed recommendations reached the 80% agreement threshold. The development of evidence-based recommendations for NPWT with direct validation from a large group of practicing clinicians offers a broader basis for consensus than work by an expert panel alone.

Abstract
Local random flaps are seldom used for reconstruction of complex ankle wounds because of concern for flap failure attributable to vascular compromise and tissue edema. Negative pressure wound therapy has been shown to improve perfusion and limit tissue edema. The objective of this study was to demonstrate the utility of negative pressure wound therapy in improving outcomes for local flaps of the ankle. Ten consecutive patients presenting with complex ankle wounds and reconstructed using local flaps were treated with negative pressure wound therapy postoperatively. Type of flap, immediate and long-term outcomes, and complications were assessed. Seventeen local flaps were performed on 10 patients to reconstruct their ankle wounds. Mean follow up was 88 days. All flaps healed without tissue compromise or necrosis. Only one partial dehiscence and no infections were observed. This study demonstrates that negative pressure therapy may contribute to the viability of random local flaps by decreasing venous congestion. Our experience using negative pressure wound therapy on local flaps suggests that it may serve as a useful adjunct to ensure successful closure of high-risk wounds.

Abstract
Since its introduction into the market, negative pressure wound therapy (NPWT), also known as topical negative pressure, has become an important adjuvant therapy for the treatment of many types of wounds. Surgeons and physicians of all subspecialties have adopted NPWT into their practices. NPWT has become a mainstay in the management of lower extremity soft tissue pathology, especially in patients with traumatic, diabetic, postsurgical, and peripheral vascular disease-associated wounds. This article reviews the background, currently understood mechanisms of action, applications, contraindications, reported complications, advantages, criticisms, and techniques in the lower extremity.

Abstract
PURPOSE The aim of the study was to report the outcomes of the vacuum dressing method (vacuum-assisted closure [VAC]) in the management of "complicated" abdominal wounds in a selected group of children including neonates. METHODS All children with vacuum (VAC) dressing-assisted closure of a complex abdominal wound (defined as complete/partial wound dehiscence combined with at least one of stoma, anastomosis, tube enterostomy, or infected patch abdominoplasty) were included in a 2-year study that took place in a single tertiary referral hospital. Retrospective case note analysis was used to determine premorbid diagnosis, management, illness severity markers, morbidity, and outcome. RESULTS Nine children (neonate to 16 years) required 11 continuous episodes of VAC therapy. Abdominal wall dehiscence was complete in 7 and partial in 4 episodes. These were complicated by stomas (8), anastomoses (3), enterocutaneous fistulae (3), tube enterostomy (1), and infected patch abdominoplasty (2). Illness severity was assessed by the following proxy physiologic markers: American Society of Anesthesiologists status 3 or more (10), intensive care unit (ICU) (7), inotropes (4), ventilation (7), septic (C-reactive protein >100 and blood culture-positive) (3), liver impairment (aspartate transaminase >58 and alanine transaminase >36) (4), coagulopathy (international normalized ratio >1.3) (4), proinflammatory state (platelet count >450) (5), and nutritional impairment (albumin <37) (9). The median VAC treatment time was 32 days (range, 9-101 days). Of the changes, 70% required a general anesthetic or sedation on ICU. Control of 10 of 11 complex abdominal wounds (including 3 established enterocutaneous fistulae) was achieved using VAC therapy. Complications included nonreduction of laparostomy (1), failure of anastomosis (1), and failure of tube enterostomy diversion (1). Four children died of unrelated causes, 2 of them more than 3 months after VAC therapy. CONCLUSIONS In our experience with a small series of patients, VAC therapy is both safe and effective in complex pediatric abdominal wounds in severely ill children. It appears to promote wound closure, controls local sepsis, and can be used to manage established fistulae. However, our results suggest that recent bowel anastomoses may be compromised using VAC, which in this circumstance, should be used with caution.
