Hydrogels have emerged as effective tools in medication delivery and tissue engineering due to their adjustable characteristics and water retention capabilities. The purpose of this work was to investigate the potential of a novel thermosensitive hydrogel composed of Pluronic F127 and polyglutamic acid (PGA) to enhance the treatment of MRSA-infected full-thickness excision wounds. The viscosity and gelation temperature of the hydrogels were evaluated using viscometry and rheometry, while their injectability was assessed with a texture analyzer. Swelling and biodegradation were measured in PBS at 37 °C, and antibacterial and antioxidant activity was determined using MIC/MBC tests and DPPH radical scavenging. In mouse infected wound healing investigations, hydrogels were applied to wounds, and tissue examination was done with Masson's Trichrome staining and biochemical assays for TAC and MDA. The F127/PGA hydrogel converted from a liquid to a gel at body temperature more efficiently than F127 alone, with lower gelation temperatures and improved mechanical characteristics. F127/PGA had higher swelling capacity and a slower degradation rate than F127. In antibacterial assays, the F127/PGA hydrogel showed stronger inhibitory and bactericidal activity against MRSA, as reflected by its lower MIC and higher MBC values. In addition, the hydrogel showed increased antioxidant activity and lower oxidative stress during wound healing, resulting in much better wound contraction and tissue regeneration than F127 and control treatments. These characteristics make F127/PGA an attractive choice for improved drug delivery systems and wound healing applications.
由于其可调节的特性和保水性,水凝胶已成为药物输送和组织工程的有效工具。本研究的目的是研究由Pluronic F127和聚谷氨酸(PGA)组成的新型热敏水凝胶对mrsa感染全层切除伤口的治疗潜力。用粘度学和流变学对水凝胶的粘度和凝胶温度进行了评估,并用织构分析仪对其注射性进行了评估。在37℃的PBS中测定溶胀和生物降解,并通过MIC/MBC试验和DPPH自由基清除测定抗菌和抗氧化活性。在小鼠感染伤口愈合研究中,将水凝胶涂在伤口上,用马松三色染色法检查组织,并进行TAC和MDA的生化检测。与单独使用F127相比,F127/PGA水凝胶在体温下更有效地从液体转化为凝胶,具有更低的凝胶温度和更好的机械特性。与F127相比,F127/PGA具有更高的溶胀能力和更慢的降解速度。在抗菌实验中,F127/PGA水凝胶对MRSA表现出较强的抑制和杀菌活性,其MIC值较低,MBC值较高。此外,水凝胶在伤口愈合过程中显示出更高的抗氧化活性和更低的氧化应激,导致伤口收缩和组织再生比F127和对照处理好得多。这些特性使F127/PGA成为改进药物输送系统和伤口愈合应用的有吸引力的选择。

Background and purpose

Unstable pelvic ring fractures are severe injuries with substantial mortality and a high burden of associated injuries. Advances in trauma care have improved outcomes. However, recent data from high-volume centers remain scarce. We aimed to evaluate mortality, associated injuries, and predictors of mortality in surgically treated unstable pelvic ring fractures.

Methods

We retrospectively analyzed 451 consecutive patients with surgically treated Tile B or C pelvic ring fractures admitted to a Level 1 trauma center between 2008 and 2021. Patient demographics, injury characteristics, and associated injuries were recorded. Kaplan–Meier methods were used to estimate survival, and Cox regression for identifying independent predictors of mortality.

Results

Overall mortality at 3-month was 4.2% (95% CI 2.3–6.0) and at 1-year at 6.0% (95% CI 3.8–8.2). Tile C fractures had a higher early mortality than Tile B (3-month: 6.5% vs. 2.1%; 1-year: 7.4% vs. 4.7%). Associated injuries were common: 78% of patients had at least one and 66% had two or more injured regions. Patients with injuries in ≥2 regions had markedly higher intensive care unit (ICU) admission, transfusion requirements, and early mortality. In multivariable Cox regression, age (HR 1.06 per year), Glascow Coma Scale (GCS) ≤8 (HR 4.9), and Tile C (HR 3.6) were independently associated with 90-day mortality.

Conclusion

Mortality after surgically treated unstable pelvic ring fractures at 3- month and 1 year was 4.2% and 6.0%, respectively. Age, low GCS, and Tile C fracture pattern were independent predictors of early death. Associated injuries and overall trauma burden were strongly associated with ICU admission, transfusion, and early mortality.
背景和目的:不稳定骨盆环骨折是一种严重的损伤,死亡率高,相关损伤负担高。创伤护理的进步改善了治疗效果。然而,最近来自高容量中心的数据仍然很少。我们的目的是评估手术治疗不稳定骨盆环骨折的死亡率、相关损伤和死亡率预测因素。方法:我们回顾性分析了2008年至2021年间在一级创伤中心连续收治的451例手术治疗的B或C级骨盆环骨折患者。记录患者人口统计、损伤特征和相关损伤。Kaplan-Meier法用于估计生存率,Cox回归用于确定死亡率的独立预测因子。结果:3个月的总死亡率为4.2% (95% CI 2.3-6.0), 1年的总死亡率为6.0% (95% CI 3.8-8.2)。C片骨折的早期死亡率高于B片(3个月:6.5% vs. 2.1%; 1年:7.4% vs. 4.7%)。相关损伤很常见:78%的患者至少有一个区域受伤,66%的患者有两个或更多区域受伤。损伤≥2个区域的患者重症监护病房(ICU)入院率、输血需求和早期死亡率明显较高。在多变量Cox回归中,年龄(HR 1.06 /年)、Glascow昏迷量表(GCS)≤8 (HR 4.9)和Tile C (HR 3.6)与90天死亡率独立相关。结论:不稳定骨盆环骨折术后3个月和1年的死亡率分别为4.2%和6.0%。年龄、低GCS和Tile C骨折类型是早期死亡的独立预测因素。相关损伤和总体创伤负担与ICU入院、输血和早期死亡率密切相关。

Background:

Chronic acromio-clavicular dislocation is a challenging injury to treat. Many surgical procedures are available for its management which may be anatomical or non-anatomical. The aim of this study was to assess the clinical and radiological outcome in the patients with chronic acromio-clavicular dislocation treated by hybrid biological semitendinosus autograft and synthetic non-absorbable sutures.

Methods:

From July 2021 to January 2025, 21 patients with chronic acromio-clavicular dislocation were treated by hybrid biological semitendinosus autograft and synthetic non-absorbable sutures. Grade III to VI chronic acromio-clavicular injuries were included. Post-operatively, the patients were clinically assessed using Constant shoulder and Acromio-clavicular joint instability scores. Acromio-clavicular arthritis, coraco-clavicular ossification, distal clavicle osteolysis, coraco-clavicular and acromio-clavicular distances were radiologically evaluated.

Results:

The mean age at time of surgery was 28.52 ± 8.0 (range: 19-45) years. The acromio-clavicular dislocation was type III in 7 patients (33.4 %), type IV in 12 patients ( %57.1) and type V in 2 patients (9.5 %). The mean follow-up period was 24.29 ± 3.51 (range: 18-30) months. The mean post-operative Acromio-clavicular joint instability and Constant shoulder scores were 93.14 ± 8.16 (range: 78-100) and 90.14 ± 8.16 (range: 80-100) points respectively. None of the patients showed recurrent dislocation, arthritis and distal clavicle osteolysis.

Conclusion:

Bi-modal stabilization using hybrid biological semitendinosus autograft and synthetic non-absorbable sutures is an effective and reliable surgical option to treat chronic acromio-clavicular dislocation. Most of the reported complications associated with this procedure didn’t affect the functional outcome.
背景:慢性肩锁脱位是一种具有挑战性的损伤治疗。许多外科手术可用于其管理,可能是解剖或非解剖。本研究的目的是评估混合生物自体半腱肌和合成不可吸收缝合线治疗慢性肩锁关节脱位的临床和影像学结果。方法:自2021年7月至2025年1月,对21例慢性肩锁关节脱位患者采用自体生物半腱骨复合人工不可吸收缝合线进行治疗。包括III至VI级慢性肩锁损伤。术后,采用恒肩和肩锁关节不稳定性评分对患者进行临床评估。肩胛骨-锁骨关节炎、喙-锁骨骨化、锁骨远端骨溶解、喙-锁骨和肩锁距离进行影像学评估。结果:手术时平均年龄28.52±8.0岁(范围:19-45岁)。肩锁关节脱位为III型7例(33.4%),IV型12例(% 57.1%),V型2例(9.5%)。平均随访时间为24.29±3.51(18-30)个月。术后肩锁关节不稳定性和肩部常数评分平均分别为93.14±8.16分(范围:78-100)和90.14±8.16分(范围:80-100)。所有患者均无复发性脱位、关节炎及锁骨远端骨溶解。结论:自体半腱肌生物混合植骨和合成不可吸收缝线的双峰稳定是治疗慢性肩锁关节脱位的有效、可靠的手术选择。大多数报道的与该手术相关的并发症不影响功能结果。

Skin flaps are widely used in plastic and reconstructive surgery. However, inadequate blood perfusion during flap mobilization can trigger an ischemic process that may lead to tissue necrosis in the absence of effective management of the inflammatory process. In this context, the search for new biocompatible strategies to ensure the viability of ischemic skin flaps (ISFs) remains necessary. Therefore, this study evaluated novel alginate-ZIF-8 (ALG-ZIF-8) hydrogel systems with Rhizophora mangle (R. mangle) extract and tannic acid (TA) to assess their potential in preventing necrosis in ISF. Twenty-two male Wistar rats underwent the surgical creation of ISF and were divided into four groups: 0.9% saline (negative control - NegC), placebo alginate hydrogel (pALGgel), ALG-ZIF-8 hydrogel system with 5% TA (ALGzTA), and finally, ALG-ZIF-8 hydrogel system with 5% R. mangle (ALGzRm). Flap outcomes were evaluated through macroscopic observation, followed by morphometric analysis of viable and necrotic areas, and histomorphometric analysis of fibroblasts, blood vessels, and leukocytes, using ImageJ and PrimeCam 5.1 software. Statistical analysis was performed using IBM SPSS software (version 27). The results suggest that the formulations produced divergent outcomes by differentially modulating inflammatory and angiogenic responses. The ALGzRm formulation tended to show a protective profile, associated with a significant reduction in leukocyte infiltration (p < 0.001), while the ALGzTA formulation was linked to a detrimental response, including exacerbated inflammation and a pathologically high blood vessel count (p = 0.015). In conclusion, findings suggest that the ALGzRm-gel has a potential for tissue repair, mediated by the modulation of inflammatory and angiogenic responses.
皮瓣广泛应用于整形和重建手术。然而,在皮瓣动员过程中,血液灌注不足会引发缺血过程,在炎症过程缺乏有效管理的情况下可能导致组织坏死。在这种情况下,寻找新的生物相容性策略来确保缺血皮瓣(isf)的生存能力仍然是必要的。因此,本研究评估了新型海藻酸盐- zif -8 (ALG-ZIF-8)水凝胶体系与根霉(R. mangle)提取物和单宁酸(TA),以评估其预防ISF坏死的潜力。22只雄性Wistar大鼠手术生成ISF,分为四组:0.9%生理盐水(阴性对照- NegC)、安慰剂海藻酸盐水凝胶(pALGgel)、5% TA的ALG-ZIF-8水凝胶体系(ALGzTA)和5% R. mangle的ALG-ZIF-8水凝胶体系(ALGzRm)。采用ImageJ和PrimeCam 5.1软件对皮瓣进行宏观观察、活区和坏死区形态学分析、成纤维细胞、血管和白细胞的组织形态学分析。采用IBM SPSS软件(27版)进行统计分析。结果表明,配方产生不同的结果,通过不同的调节炎症和血管生成反应。ALGzRm配方倾向于显示出保护作用,与白细胞浸润的显著减少有关(p < 0.001),而ALGzTA配方与有害反应有关,包括炎症加剧和病理性高血管计数(p = 0.015)。总之,研究结果表明,通过调节炎症和血管生成反应,algzrm -凝胶具有组织修复的潜力。

Introduction

Open globe injury is a surgical emergency requiring prompt diagnosis to minimize morbidity. Orbital CT is frequently performed in trauma settings and is crucial for globe evaluation, particularly when bedside assessment is limited.
The primary objective was to evaluate the diagnostic accuracy of overall CT impression for detecting open globe injury. The secondary objective was to assess the diagnostic accuracy of CT imaging signs.

Methods

A systematic review protocol was prospectively registered (PROSPERO CRD42025638703). On January 16, 2025, Embase, Pubmed, Scopus, and Google Scholar were searched without date restrictions. Diagnostic accuracy meta-analyses were performed on overall CT impression and individual CT imaging signs for open globe injury. Risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool.

Results

Eight studies met inclusion criteria representing 827 patients, 830 injured globes, and 339 confirmed open globe injury. The pooled sensitivity and specificity of overall CT impression was 75% (95% CI, 0.69–0.79) and 94% (95% CI, 0.91–0.96), respectively. Among individual signs, change in globe contour or scleral irregularity had the highest diagnostic odds ratio (109; 95% CI, 17–718) with sensitivity and specificity of 71% (95% CI, 0.61–0.79) and 98% (95% CI, 0.86–1.00), respectively. Change in anterior chamber depth, vitreous hemorrhage, lens abnormality, and intraocular air were insensitive but highly specific signs.

Conclusions

Overall CT impression and individual imaging signs demonstrate high specificity but limited sensitivity for open globe injury. Surgical exploration remains necessary when clinical suspicion persists despite inconclusive imaging.
开放球损伤是一种外科急诊,需要及时诊断以减少发病率。眶部CT经常在创伤情况下进行,对全球评估至关重要,特别是当床边评估有限时。本研究的主要目的是评估CT整体成像检测开放性球损伤的诊断准确性。次要目的是评估CT影像征象的诊断准确性。方法前瞻性注册一项系统评价方案(PROSPERO CRD42025638703)。2025年1月16日,检索Embase、Pubmed、Scopus和谷歌Scholar,没有日期限制。诊断准确性荟萃分析对开放球损伤的整体CT印象和个体CT成像征象进行分析。使用诊断准确性研究质量评估-2工具评估偏倚风险。结果8项研究符合纳入标准,共有827例患者,830例损伤球,339例确认开放球损伤。CT总体印象的敏感性和特异性分别为75% (95% CI, 0.69-0.79)和94% (95% CI, 0.91-0.96)。在个体体征中,眼球轮廓改变或巩膜不规则具有最高的诊断优势比(109;95% CI, 17-718),敏感性和特异性分别为71% (95% CI, 0.61-0.79)和98% (95% CI, 0.86-1.00)。前房深度改变、玻璃体出血、晶状体异常和眼内空气不敏感,但具有高度特异性。结论CT总体印象和个别影像学征象对开放性球损伤具有较高的特异性,但敏感性有限。当临床怀疑持续存在而影像学不确定时,手术探查仍然是必要的。

The median and interquartile range of the infection history was 6 (2, 66) months. The infected skeletal sites included 7 cases in the tibia and 3 in the femur. All cases underwent the modified Masquelet technique, which included two-stage surgical approaches: the first-stage surgery (FSS) involved debridement, bone cement filling, soft tissue coverage, and external fixation; the second-stage surgery (SSS) included removal of the bone cement, FVFG, iliac bone grafting, and external fixation. The bone defect sizes ranging from 9.7 to 22.4 cm (16.4 ± 4.1 cm). The median and quartile of the bone defect volume were 70.1 (52.1, 139.9) cm<sup>3</sup>. The size of the vascularized fibula varied from 11.3 to 21.0 cm (17.2 ± 3.7 cm). Postoperatively, patients were followed for a duration ranging from 12 to 31 (19.7 ± 6.4) months. Bone graft fusion was assessed according to the radiographic union score (RUS), with scores greater than 8 indicating successful bone fusion.

Background

Fragility fractures of the pelvis (FFP) are increasingly common, particularly in the ageing population. Traditionally, those low-energy pelvic ring fractures have been managed conservatively, but this approach can lead to immobility and therefore complications. Surgical intervention is indicated based on various factors including type of fracture, mobility, and pain. Minimal-invasive percutaneous sacroiliac and/or transsacral screw stabilisation offers an effective treatment, enabling immediate mobilisation. There are multiple technical methods for the implantation. This study aimed to assess the precision of CT-guided percutaneous screw stabilisation and functional outcomes in elderly patients with FFP.

Methods

A retrospective analysis was conducted on 114 elderly patients who underwent CT-controlled percutaneous sacroiliac screw implantation for FFP between 2010 and 2021. Data on demographics, pre-operative characteristics, surgical procedure, and postoperative outcomes were collected from routine data and analysed.

Results

Stabilisation using CT-guidance demonstrated favourable outcomes with low rates of screw malposition. 96% of the sacroiliac screws in S1 were placed completely intraosseous. Sacroiliac placement showed higher rates of completely intraosseous placement than transsacral placement. Placement in S1 showed higher accuracy rates than placement in S2. Operations with more radiation had a higher percentage of perfectly positioned screws and the simple fracture type had more perfectly positioned screws than the more complex type FFP4. Eighteen screws showed signs of loosening after one year, necessitating re-operation in 2 cases. Patients with 3 screws had less risk of loosening. Screws inserted from the left showed lower rates of loosening than screws from the right. Postoperative mobility assessment showed that 70% were still living at home after one year and 63% were painfree. The one-year mortality was 18%.

Conclusion

CT-guided implantation of 231 sacrum screws had a very high precision with no malpositioned screws. The precision of implantation is not affected by the BMI or age of the patient, but the rate of perfect position was lower in complex fractures than in simple fractures. Precision of sacroiliac screw implantation is higher than that of transsacral screws but the rate of loosening is not higher. Surgery provided freedom from pain for most patients and only few patients lost their self-dependence.
背景:骨盆脆性骨折(FFP)越来越常见,特别是在老龄化人口中。传统上,低能量骨盆环骨折的治疗方法比较保守,但这种方法可能导致不活动和并发症。手术干预是根据不同的因素,包括骨折类型,活动能力和疼痛。微创经皮骶髂和/或经骶螺钉固定提供了有效的治疗,使患者能够立即活动。植入有多种技术方法。本研究旨在评估ct引导下经皮螺钉稳定的准确性和老年FFP患者的功能结局。方法:回顾性分析2010 - 2021年间114例行ct控制下经皮骶髂螺钉植入术治疗FFP的老年患者。从常规资料中收集人口统计学、术前特征、手术程序和术后结果的数据并进行分析。结果:ct引导下的稳定显示出良好的结果,螺钉错位率低。骶S1区96%的骶髂螺钉完全置入骨内。骶髂置入术显示完全骨内置入术的比例高于经骶骨置入术。S1位置的准确率高于S2位置。放疗较多的手术有较高的螺钉完美定位比例,简单骨折类型比复杂骨折类型的FFP4有更多的螺钉完美定位。18例1年后出现松动现象,2例需再次手术。使用3枚螺钉的患者松动的风险较小。从左侧插入的螺钉松动率低于从右侧插入的螺钉。术后活动能力评估显示,70%的患者一年后仍在家中生活,63%的患者无痛。一年死亡率为18%。结论:ct引导下231枚骶骨螺钉置入精度高,无螺钉错位。植入精度不受患者BMI和年龄的影响,但复杂骨折的完美位置率低于单纯骨折。骶髂螺钉植入精度高于经骶螺钉,但松动率不高。手术使大多数患者摆脱了痛苦,只有少数患者失去了自我依赖。

Introduction

Trauma results in approximately 1.19 million deaths and 20–50 million disabilities globally each year. With increasing industrialization, road traffic injuries have become a leading cause of Disability Adjusted Life Years and traumatic amputations. These sudden amputations often lead to significant psychological distress. This study aims to assess the effectiveness of psychosocial interventions in enhancing the Quality of Life of post-traumatic amputees.

Material and Methods

This randomized controlled trial enrolled 74 post-traumatic extremity amputees aged over 18 years, who were cognitively coherent, had adequate social support, and no prior psychological illness. Following baseline psychosocial assessment, participants were randomly assigned to two groups: Group A (n = 39) received conventional care, while Group B (n = 35) received both psychosocial intervention and conventional care for seven weeks. Psychosocial outcomes were reassessed in both groups at the eighth week post-intervention.

Results

Quality of life showed significant improvement in both the groups. However, there was no significant difference between the groups. Level of depression, anxiety and stress significantly decreased in both the groups at 8 weeks, but the difference was not significant between the groups. However, body image showed a significant improvement in Group B as compared to Group A (p = 0.023).

Conclusion

Our study did not show any observable positive effects of psychosocial intervention over conventional care on quality of life, depression, stress, or anxiety except on body image. We hypothesize that positive results might be seen in quality of life of amputees if a larger study with longer duration of psychosocial intervention is conducted.
导言:全球每年约有119万人死于创伤,2000万至5000万人残疾。随着工业化程度的提高,道路交通伤害已成为伤残调整寿命年和创伤性截肢的主要原因。这些突然的截肢通常会导致严重的心理困扰。本研究旨在评估心理社会干预在提高创伤后截肢者生活质量方面的有效性。材料和方法:本随机对照试验招募了74名18岁以上的创伤后四肢截肢者,他们认知连贯,有足够的社会支持,没有先前的心理疾病。在基线心理社会评估之后,参与者被随机分为两组:A组(n = 39)接受常规护理,而B组(n = 35)接受心理社会干预和常规护理,为期7周。在干预后第8周对两组患者的心理社会结果进行重新评估。结果:两组患者的生活质量均有明显改善。然而,两组之间没有显著差异。8周时,两组患者抑郁、焦虑和压力水平均显著降低,但两组间差异不显著。然而,与a组相比,B组的身体形象有显著改善(p = 0.023)。结论:除了身体形象,我们的研究没有显示任何可观察到的心理社会干预在生活质量、抑郁、压力或焦虑方面优于传统护理的积极作用。我们假设,如果进行更大规模的长期社会心理干预研究,可能会在截肢者的生活质量方面看到积极的结果。

Background

Acute Compartment Syndrome (ACS) is a severe condition that can threaten limb viability, particularly in patients who experience prolonged immobility, such as in the found-down phenomenon. Inadequate removal of nonviable muscle after fasciotomy increases the risk of infection. While non-invasive imaging modalities have been explored for early ACS diagnosis, no tools currently exist to guide precise debridement intraoperatively. Existing technologies are limited by susceptibility to interference, lack of standardized thresholds and insufficient real-time surgical utility. This study aimed to evaluate the association between muscle perfusion, quantified by indocyanine green (ICG)-based dynamic contrast-enhanced fluorescence imaging (DCE-FI), and the degree of muscle necrosis in ACS, assessed via histopathological analysis, to explore the potential of DCE-FI to guide intraoperative muscle debridement.

Methods

A total of 15 adults (aged 18 years or older) undergoing ACS surgical treatment were included in this study between 2023 and 2024. DCE-FI imaging was performed and eight muscle specimens spanning the entire length of the incision were obtained for each patient. Necrosis percentage was assigned to each sample based on histopathological evaluation by a pathologist. Patients were then classified into high necrosis (HN) and low necrosis (LN) groups based on their average necrosis scores from these eight samples, using 50 % necrosis as a cutoff. Perfusion-related kinetic parameters derived from DCE-FI, including maximum fluorescence intensity (Imax) and blood flow (BF), were evaluated and compared between the two groups.

Results

The HN group exhibited significantly lower Imax (p < 0.001) and BF (p < 0.001), compared to those in the LN group, indicating substantially reduced muscle perfusion. The HN group had significantly lower median values (Imax 23.0 RFUs, BF 1.9 mL/min/100g) compared to the LN group (Imax 32.4 RFUs, BF 3.1 mL/min/100g).

Conclusions

ICG-based DCE-FI demonstrated strong potential for intraoperative identification of muscle damage resulting from ACS. This technique may serve as a valuable adjunct for guiding surgical debridement which may minimize complications and reduce the number of debridement procedures required, particularly in challenging cases of delayed or missed diagnosis of compartment syndrome.
背景:急性筋膜间室综合征(ACS)是一种严重的疾病,可威胁肢体的生存能力,特别是在经历长期不活动的患者中,如发现倒下现象。筋膜切开术后不适当切除不存活的肌肉会增加感染的风险。虽然非侵入性成像方式已被用于早期ACS诊断,但目前还没有工具可以指导术中精确清创。现有的技术受制于易受干扰、缺乏标准化阈值和实时手术效用不足。本研究旨在评价以吲哚菁绿(ICG)为基础的动态对比增强荧光成像(DCE-FI)量化的肌肉灌注与ACS的肌肉坏死程度之间的关系,并通过组织病理学分析评估,探讨DCE-FI指导术中肌肉清创的潜力。方法:在2023年至2024年期间,共纳入15名接受ACS手术治疗的成年人(18岁或以上)。进行DCE-FI成像,为每位患者获得8个横跨整个切口长度的肌肉标本。根据病理学家的组织病理学评估,分配每个样本的坏死百分比。然后根据这8个样本的平均坏死评分将患者分为高坏死(HN)组和低坏死(LN)组,坏死以50%为截止值。DCE-FI获得的灌注相关动力学参数,包括最大荧光强度(Imax)和血流量(BF),进行评估和比较。结果:与LN组相比,HN组的Imax (p < 0.001)和BF (p < 0.001)明显降低,表明肌肉灌注明显减少。与LN组(Imax 32.4 RFUs, BF 3.1 mL/min/100g)相比,HN组的中位值(Imax 23.0 RFUs, BF 1.9 mL/min/100g)显著降低。结论:基于icg的DCE-FI显示了术中识别ACS引起的肌肉损伤的强大潜力。该技术可作为指导手术清创的一种有价值的辅助手段,可以最大限度地减少并发症,减少所需的清创手术次数,特别是在延迟或漏诊筋膜间室综合征的挑战性病例中。
