Background
Biological grafts are the preferred option for in situ aortic reconstruction following infections, offering good survival and low complications rates. Vein harvesting may be challenging or undoable in emergency setting. Hence, xenogeneic materials, such as bovine grafts, gained popularity due to their availability, biocompatibility, and low reinfection rates despite data on their outcomes remain limited.
Methods
A systematic review and metanalysis was conducted following Preferred Reporting Items for Systematic Reviews, and Meta-Analyses and Population, Intervention, and Outcome guidelines using PubMed, Scopus, and Web of Science. Two independent reviewers selected studies, extracted data, and assessed quality. A random-effects meta-analysis was done to evaluate survival, patency, and recurrence. Precision was assessed through 95% confidence intervals (CIs), and publication bias was examined using funnel plots and Egger's test. The review was registered in International prospective register of systematic reviews (CRD42024629225).
Results
Out of 96 papers screened, 15 studies (300 patients, 81.6% male, mean age 70.5 years) were included. The abdominal aorta was the most frequently treated segment (78.6%), followed by the descending thoracic (9%), thoracoabdominal aorta (6.3%), and ascending/arch (6%). Gram-positive bacteria were the most common pathogens (34.6%) encountered, followed by gram-negative (19%) and fungal infections (10%). Bovine pericardium in situ reconstruction was associated with a 30-day mortality rate of 19.8% (95% CI: 15.0%–25.7%), and an overall mortality of 30.5% (95% CI: 24.2%–37.6%). At a mean follow-up of 18.7 months, reinfection rate was 8.9% and patency rate 92.9%.
Conclusion
Bovine grafts show promising midterm results in treatment of aortic infections, assuring good survival and low recurrence rates at the midterm follow-up. Long-term data and comparative studies are needed to confirm their broader applicability.
背景：生物移植物是感染后主动脉原位重建的首选，具有良好的存活率和低并发症发生率。在紧急情况下，静脉采集可能具有挑战性或不可行的。因此，异种材料，如牛移植物，由于其可用性、生物相容性和低再感染率而受到欢迎，尽管其结果的数据仍然有限。方法：采用PubMed、Scopus和Web of Science，按照PRISMA和PIO指南进行系统综述和荟萃分析。两名独立审稿人选择研究、提取数据并评估质量。随机效应荟萃分析评估生存、通畅和复发率。精确度通过95%置信区间评估，发表偏倚采用漏斗图和Egger检验。该审查已在PROSPERO注册（CRD42024629225）。结果：筛选96篇论文，纳入15项研究（300例患者，81.6%男性，平均年龄70.5岁）。腹主动脉是最常见的治疗段（78.6%），其次是胸降主动脉（9%）、胸腹主动脉（6.3%）和升/弓主动脉（6%）。革兰氏阳性菌感染最多（34.6%），其次为革兰氏阴性菌感染（19%）和真菌感染（10%）。牛心包原位重建的30天死亡率为19.8% (95% CI: 15.0%-25.7%)，总死亡率为30.5% （95% CI: 24.2%-37.6%）。平均随访18.7个月，再感染率8.9%，通畅率92.9%。结论：牛主动脉瓣移植治疗主动脉感染中期疗效良好，中期随访存活率高，复发率低。需要长期的数据和比较研究来证实其更广泛的适用性。

Background
Blunt thoracic aortic injury (BTAI) is one of the leading causes of death after trauma. Current guideline recommendations are primarily based on short-term outcomes, while longer-term outcomes are not well investigated. This study aims to investigate the safety of nonoperative management (NOM) for minor and more severe aortic injuries and the need for follow-up.
Methods
We performed a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included studies from the forming of the databases till May 2025, evaluating the results of NOM on mid-term (≥12 months) or long-term clinical outcomes for patients with BTAI. Nine retrospective and observational studies comprising 438 patients were included. The overall methodological quality was moderate to low. Outcomes evaluated are aortic-related mortality, lesion evolution, aortic-related intervention and all-cause mortality.
Results
Nine retrospective and observational studies comprising 438 patients were included. Of all patients, 29% had a Society of Vascular Surgery (SVS) grade I aortic injury, 27% grade II, 35% grade III, and 1% grade IV. After a mean follow-up of 37.7 months, no progression was observed in SVS grade I and II injuries. The pooled estimate for lesion progression in SVS grade III was 7% (95% confidence interval (CI): 0–14; I2 = 23.2%). Lesion resolution occurred in 83% of SVS grade I and 50% of grade II injuries. Most grade III lesions (81%) remained stable (95% CI: 63–99; I2 = 83.64%). The pooled rate of all-cause mid-term mortality was 3% (95% CI: 0–0.07), while this was 2% for aortic-related intervention (95% CI: 0–4).
Conclusion
This meta-analysis, including only retrospective and observational studies, shows that minor aortic injuries will remain stable or resolve with time and can be managed conservatively with appropriate surveillance. The risk of lesion progression for conservatively treated patients with SVS grade III is low.

Anatomic suitability for endovascular aortic surgery has rapidly expanded to include the juxtarenal and paravisceral segment. Traditional infrarenal endovascular devices are not suitable for use in short neck, angulated, or complex aneurysms that involve the visceral-renal segment of the aorta due to lack of appropriate seal zones or coverage of visceral-renal arteries. There are few commercially available devices in the United States approved for treatment of these complex abdominal aortic aneurysms, one of which requires a 6–8 week waiting period for patient-specific custom fabrication. Physician-modified endografts (PMEGs) have been increasingly adopted as readily available solutions to offer expeditious repair of these anatomically complex aneurysms. PMEG can incorporate various modifications, including fenestrations and directional branches, to accommodate a wide range of anatomies, without need for waiting periods for device fabrication. The authors describe modern planning and technical methods for incorporation of visceral and renal arteries using PMEG created from commercially available endografts.

背景：腹主动脉瘤（AAA）在女性中较男性少见，但当出现时，女性似乎遵循更具侵袭性的病程，在较小直径处破裂，经历较差的手术结果。英国提供了一个独特的环境来评估性别特异性的结果，因为国家筛查邀请仅适用于男性，NICE指南适用于不分性别的统一5.5厘米的选择性修复阈值。方法：根据PRISMA 2020进行系统评价。检索到2025年9月的MEDLINE、EMBASE和Cochrane图书馆。符合条件的研究报告了英国AAA患者的性别分层结局。灰色文献通过审查国家血管登记处（NVR）、NHS AAA筛查计划报告和NICE指南纳入。在分子和分母有性别分层的情况下，使用Der simonan - laird随机效应模型计算和汇总粗比值比（or）。使用通用反方差法对报告多变量调整后的or的研究进行单独的调整后效应荟萃分析。结果：五项同行评议的研究符合纳入标准，并得到国家报告的支持。择期血管内修复术后女性围手术期死亡率显著高于择期血管内修复（合并OR为1.61,95% CI为1.31-1.97）和择期开放式修复（合并OR为1.37,95% CI为1.16-1.63）。在破裂修复后，EVAR术后的死亡率在性别之间相似（合并OR为1.11,95% CI为0.89-1.39），但女性在开放手术后的死亡率更高（合并OR为1.53,95% CI为1.24-1.89），尽管存在很大的异质性。调整效应综合证实，女性择期EVAR（总校正OR≈1.55,95% CI 1.25-1.80）和开放式修复（校正OR 1.39, 95% CI 1.25-1.56）后死亡率更高。女性在破裂后接受手术的可能性较小，在选择性EVAR后再次入院的可能性更大，住院时间更长，长期主动脉相关死亡率更高。结论：在英国，患有AAA的女性在每个护理阶段都处于不利地位：她们不太可能被筛查，直径较小的破裂，很少被选择修复，并且在治疗时，面临更高的围手术期和长期死亡率。这些差异反映了解剖学和生物力学的差异，以及系统因素。英国目前的政策，基于男性筛查和性别中立的5.5厘米门槛，并没有反映出这一现实。为了解决不平等问题，需要针对性别的修复阈值、有针对性的女性筛查以及针对女性解剖结构优化的设备开发。

Objectives
Supraceliac clamping may be required during repair of short-neck or juxtarenal abdominal aortic aneurysms (AAAs). Its use remains controversial, mainly due to potential renal risks. This study reports the outcomes of its routine use in the surgical management of these complex aneurysms.
Methods
Between January 2008 and December 2024, 207 patients underwent open repair of short-neck or juxtarenal AAAs. Data were retrospectively analyzed, including demographic variables, aneurysm characteristics, intraoperative details, and early morbidity and mortality outcomes. The primary end point was postoperative acute kidney injury (AKI) according to the Risk, Injury, Failure, Loss, End-stage kidney disease classification. Secondary end points included early morbidity and mortality, as well as overall survival at 1 and 5 years.
Results
During the study period, 114 patients required an infrarenal clamp and 93 a supraceliac clamp. The median age was 67 years. Early morbidity and mortality outcomes were compared between the infrarenal and supraceliac clamping groups. No increased risk of postoperative AKI was observed (23% vs. 32%, P = 0.22). The 30-day mortality rate was 2% and did not differ according to clamp level. In multivariate analysis, preexisting chronic kidney disease, greater blood loss, and the presence of atheroma in the proximal neck were independently associated with postoperative AKI (odds ratio 7.0, P = 0.01).
Conclusion
Routine use of supraceliac clamping for the repair of short-neck or juxtarenal AAAs appears to be an efficient and rapid technique, without increasing short-term morbidity or mortality, particularly regarding renal outcomes.
目的：在短颈或脐旁腹主动脉瘤（AAA）的修复中，可能需要在腹腔上夹持。它的使用仍然存在争议，主要是由于潜在的肾脏风险。本研究报告了其在这些复杂动脉瘤的外科治疗中的常规应用的结果。方法：2008年1月至2024年12月，207例患者行短颈或肾旁AAAs开放性修复术。回顾性分析数据，包括人口统计学变量、动脉瘤特征、术中细节、早期发病率和死亡率结果。主要终点是术后急性肾损伤（AKI）。次要终点包括早期发病率和死亡率，以及1年和5年的总生存率。结果：在研究期间，114例患者需要肾下夹，93例患者需要腹腔上夹。中位年龄为67岁。比较肾下夹紧组和腹腔上夹紧组的早期发病率和死亡率。未观察到术后AKI风险增加（23%对32%，p = 0.22）。30天死亡率为2%，并无不同钳位水平的差异。在多变量分析中，先前存在的慢性肾脏疾病、大量失血和颈部近端存在动脉粥样硬化与术后AKI独立相关（OR 7.0, p = 0.01）。结论：常规使用乳糜上夹持术修复短颈或肾旁动脉粥样硬化是一种高效、快速的技术，不会增加短期发病率或死亡率，特别是在肾脏方面。

Background
This study aims to assess the technical feasibility and biocompatibility of interventional application of a fully absorbable stent in renal arteries (RAs) of healthy pigs.
Methods
Absorbable poly(L-lactide) (PLLA)/poly(4-hydroxybutyrate) scaffolds either loaded with sirolimus (SIR) coating or unloaded and permanent bare metal stents (BMSs) served as control were implanted interventionally into RAs of 16 female pigs via the left common iliac artery (8F-sheath). Peroral dual antiplatelet therapy was administered throughout the study. Stented RA segments were explanted after 4 weeks and assessed histomorphometrically.
Results
The polymer scaffolds showed a decreased residual lumen area and higher stenosis after 4 weeks (unloaded PLLA-based: 6.5 ± 1.0 mm2 and 44.1 ± 7.4%; SIR-PLLA-based: 8.6 ± 0.5 mm2 and 32.7 ± 0.7%) compared to BMS (11.8 ± 4.3 mm2 and 23.0 ± 4.5%). Incorporation of SIR reduced the significantly higher inflammation of unloaded scaffolds; however, not to a level compared to BMS (unloaded PLLA-based: 1.3 ± 0.3; SIR-PLLA-based: 0.9 ± 0.3; BMS: 0.5 ± 0.1). In contrast, BMS showed a slightly elevated vascular injury score (0.8 ± 0.1) compared to the unloaded PLLA-based (0.6 ± 0.2) and the SIR-PLLA-based (0.4 ± 0.04) groups.
Conclusion
Absorbable scaffolds showed sufficient mechanical stability after porcine RA stenting. By incorporation of SIR, a significant reduction of the inflammatory and neointimal response to the unloaded polymer scaffolds was seen without systemic toxicity or thrombotic complications. However, the greater strut height of the polymer scaffold is a major limitation and need to be addressed in future work on the stent design.

Background
Standard catheter-directed thrombolysis (CDT) (S-CDT) is widely accepted as a safer alternative to open surgery for acute limb ischemia (ALI), but data on ultrasound-enhanced CDT (UE-CDT) for limb salvage are limited. This study compares outcomes of UE-CDT versus S-CDT.
Methods
A 10-year single institution retrospective review identified 68 adult patients who underwent 93 CDT events for ALI, including 62 with UE-CDT and 22 with S-CDT. Following intervention, inpatient, 30 day, and 90 day outcomes were compared; one outcome for comparison was major adverse limb events (MALEs) defined as amputation of any type.
Results
No significant differences were observed between UE-CDT and S-CDT in hospital stay (5.6 vs. 7.1 days, P = 0.31), intensive care unit stay (2.5 vs. 2.9 days, P = 0.26), or duration of thrombolysis (24.2 vs. 29.6 hours, P = 0.39). Technical success was achieved in 92% of UE-CDT cases and 95% of S-CDT cases. At 30 days, UE-CDT patients had significantly fewer MALEs compared to S-CDT (6.5% vs. 31.8%; P = 0.01). However, when amputation type was stratified between digit amputation versus above/below knee amputation, there was only a significant difference between digit amputations in the S-CDT compared to UE-CDT at 30 days (P = 0.004). Otherwise, there was no significant difference between the groups at 30 and 90 days when comparing rates of above ankle amputations.
Conclusion
UE-CDT and S-CDT for ALI show similar hospital and procedural outcomes. However, UE-CDT is associated with lower 30-day MALE, driven by reduced digit amputations, and becomes nonsignificant when stratifying by above ankle amputations.
背景：标准导管定向溶栓（S-CDT）被广泛接受为急性肢体缺血（ALI）的开放手术更安全的替代方案，但超声增强CDT （UE-CDT）用于肢体保留的数据有限。本研究比较了UE-CDT和S-CDT的结果。方法：一项为期10年的单机构回顾性研究确定了68名因ALI接受了93次CDT事件的成年患者，其中62例为UE-CDT， 22例为S-CDT。干预后，比较住院、30天和90天的结果；比较的一个结果是主要肢体不良事件（MALE），定义为任何类型的截肢。结果：UE-CDT和S-CDT在住院时间（5.6天对7.1天，p=0.31）、ICU住院时间（2.5天对2.9天，p=0.26）和溶栓时间（24.2小时对29.6小时，p=0.39）方面均无显著差异。92%的UE-CDT病例和95%的S-CDT病例取得了技术上的成功。在30天，与S-CDT患者相比，UE-CDT患者的MALE显著减少（6.5% vs. 31.8%; p=0.01）。然而，当截肢类型在手指截肢与膝盖上下截肢之间分层时，30天手指截肢与UE-CDT相比，S-CDT只有显著差异（p=0.004）。另外，30天和90天时，两组间比较踝关节以上截肢率无显著差异。结论：UE-CDT和S-CDT对ALI的医院和手术结果相似。然而，UE-CDT与较低的30天MALE相关，由手指复位截肢驱动，并且在踝关节以上截肢分层时变得不显著。
