ABSTRACT
BACKGROUND: Pediatric extremity vascular injuries constitute a rare yet serious entity that can lead to serious complications especially if left untreated or become late diagnosed. In our scoping review, we sought to evaluate different characteristics and outcomes of pediatric and combined adult trauma centers (ATCs) in the management of pediatric extremity vascular injury. METHODS: We sought to analyze various characteristics and parameters that differentiate a dedicated pediatric and a combined pediatric ATC in terms of effectiveness and quality of care in the acute setting and to describe special features and characteristics of an acute vascular disease that constitute pediatric population unique from the aspect of diagnosis and management. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping reviews guidelines to conduct the study. RESULTS: The search identified 8,815 records in title using MeSH terms from PubMed/MEDLINE database among which 12 studies reporting a total of 2,124 pediatric patients with vascular extremity injuries were included for analysis. Incidence of pediatric extremity vascular injury was 0.5%. Upper extremity injuries were the most frequent presenting in 63% of cases followed by lower extremity injuries in 37% of cases. Blunt injuries were marginally more common than penetrating injuries (58% vs. 42%). In-hospital mortality and morbidity ranged from 13.2% to 0.9% and 13% to 30%, respectively. Limb-salvage rates were high, ranging from 92% to 99%. Furthermore, there are no clearly defined clinical guidelines involving the mode of imaging and diagnosis, the surgical specialties involved and the competency of nursing or medical staff overall. CONCLUSIONS: Dedicated children trauma centers theoretically represent the optimal path for acute pediatric trauma admission, especially in complex trauma necessitating vascular reconstruction. However, in the current setting of rapidly increasing health costs and economic crisis worldwide, regional or resource-related factors make this option rather unavailable. In any case, it is imperative the clinicians have a high index of suspicion when confronting with these types of injuries because early diagnosis is highly related with reduced morbidity and superior outcomes.

Chronic limb-threatening ischemia (CLTI) represents one of the most severe forms of peripheral arterial disease implying impaired wound healing and tissue loss at the same time posing a significant impact on the quality of life of patients and a serious economic burden on healthcare systems around the world. A major challenge in the management of patients with CLTI is the validity and role of non-invasive hemodynamic parameters in assessing their clinical status before and after revascularization. Traditionally, the diagnosis of CLTI is routinely based on clinical symptoms and confirmed by measurements of non-invasive limb hemodynamics including ankle-brachial pressure index (ABPI) and toe-brachial pressure index (TBPI). However, whether these indices alone can provide definitive treatment or be used as adjunctive tool along with the implementation of novel techniques to help guide revascularization for CLI patients still remains unclear.

BACKGROUND: Small abdominal aortic aneurysms (AAAs) are asymptomatic but can potentially lead to rupture if left undetected. To date, there is a lack of simple nonradiologic routine tests available for diagnosing AAAs. MicroRNAs (miRNAs) have been proven to be good-quality biomarkers in several diseases, including AAA. METHODS: An attempt to identify a panel of circulating miRNAs with differential expression in AAAs via next-generation sequencing (NGS) was performed in serum samples: small AAAs (n = 3), large AAAs (n = 3), and controls (n = 3). For miR-24, validation with real-time polymerase chain reaction (PCR) was undertaken in a larger group (n = 80). RESULTS: In the NGS study, 23 miRNAs were identified as differentially expressed (with statistical significance) in small AAAs in comparison with controls. Among them, miR-24 showed the largest upregulation with 23-fold change (log2FC 4.5, P = 0.024). For large AAAs compared with controls, and small AAAs compared with large AAAs, a panel of 33 and 131 miRNAs showed statistically significant differential expression, respectively. Based on the results of the NGS stage, a literature search was performed, and information regarding AAA pathogenesis, coronary artery disease, and peripheral arterial disease was documented where applicable: miR-24, miR-103, miR-193a, miR-486, miR-582, and miR-3663. Of these 6 miRNAs, miR-24 was chosen for further validation with real-time PCR. Additionally, in the NGS study analysis, 17 miRNAs were common between the small-large AAAs, small AAAs-controls, and large AAAs-controls comparisons: miR-7846, miR-3195, miR-486-2, miR-3194, miR-5589, miR-1538, miR-3178, miR-4771-1, miR-5695, miR-6504, miR-1908, miR-6823, miR-3159, miR-23a, miR-7853, miR-496, and miR-193a. Interestingly, in the validation stage with real-time PCR, miR-24 was found downregulated in small and large AAAs compared with controls (fold-changes: 0.27, P = 0.015 and 0.15, P = 0.005, respectively). No correlation was found between average Ct values, aneurysm diameter, and patients' age. CONCLUSIONS: Our findings further highlight the importance of miR-24 as a potential biomarker as well as a therapeutic target for abdominal aneurysmal disease. Future research and validation of a panel of miRNAs for AAA would aid in diagnosis and discrimination between diseases with overlapping pathogeneses.

OBJECTIVE: Late rupture after endovascular aortic aneurysm repair (EVAR) for an abdominal aortic aneurysm (AAA) is an increasing complication associated with a high mortality rate. This study aimed to analyse the causes and outcomes in patients with AAA rupture after EVAR. METHODS: A multi-institutional Greek study of late ruptures after EVAR between 2008 - 2022 was performed. Primary outcomes were intra-operative and in hospital death. RESULTS: A total of 70 patients presented with late rupture after EVAR (proportion of ruptured EVARs among all EVARs, 0.6%; 69 males; mean age 77.2 ± 6.7 years). The mean time interval between EVAR and late rupture was 72.3 months (range 6 - 180 months). In all cases the cause of rupture was the presence of an endoleak (type I, 73%) with sac enlargement. Moreover, 34% of subjects with rupture after EVAR had been lost to follow up and 32% underwent a secondary intervention. Additionally, 57 patients (81%) were treated by conversion to open surgical repair (COSR) and the remainder by endovascular correction of endoleak (ECE). Eleven intra-operative deaths (16%) were recorded. The overall in hospital mortality rate was 41% (23% ECE vs. 46% COSR; p = .21). Of the patients who presented as initially haemodynamically stable, 23% died during hospitalisation, while the respective mortality rate for patients who presented as unstable was 78% (odds ratio [OR] 11.8, 95% confidence interval [CI] 3.6 - 39.1; p < .001). Multivariable logistic regression analysis revealed that severity of haemodynamic shock was the most significant risk factor for intra-operative (OR 7.15, 95% CI 1.58 - 32.40; p = .010) and in hospital death (OR 9.53, 95% CI 2.79 - 32.58; p < .001). CONCLUSION: These data underline the devastating prognosis of late rupture after EVAR. Haemodynamic status at presentation was an important predictive factor for death both in the ECE and COSR groups. Rigorous follow up and prompt evaluation of an unstable patient in case of rupture after EVAR is recommended.

BACKGROUND: Management of a heavily calcified atherosclerotic occlusive disease involving the common femoral artery (CFA) and external iliac artery (EIA), poses a surgical challenge. Though the current guidelines recommend open surgical therapy for such lesions, this approach is neither easy nor represents the current real-life practice. PURPOSE: To describe tips and tricks facilitating the hybrid technique for the management of distal iliofemoral atherosclerotic disease, where classic endarterectomy is inadequate or ill-performed. TECHNIQUE: A contralateraly inserted guidewire reaches the distal iliac artery via the crossover technique and is directly retrieved from the femoral arteriotomy immediately after removal of the anterior plaque segment. The retrieved and secured guidewire enables extensive retrograde CFA endarterectomy over the wire with avusion proximally to the inguinal ligement, followed by patch arterioplasty. Externalizing the guidewire from the patch enables traction on it and facilitates advancement of the stent through tortuous or stenosed iliac vessels as well as accurate stent deployment to cover the margin of the EIA residual plaque. Moreover, this manipulation enables ipsilateral placement of a sheath and passage of a second, retrograde guidewire to perform kissing stenting in the common iliac vessels. Chronic thrombotic lesions require covered stents to avoid thrombus propagation and meticulous flushing before completion of the femoral patching. CONCLUSIONS: The combined iliofemoral endarterectomy with stenting does not require advanced endovascular skills and prevents complications associated with incomplete femoral endarterectomy. Extensive avulsion endarterectomy proximal to the inguinal ligament is efficiently and safely performed over a retrieved crossover guidewire, enabling precise residual stenting above the flexion site.
ABSTRACT
BACKGROUND: To evaluate the implementation of routine surveillance using ultrasound on hemodialysis vascular access (VA) outcomes and determine the number and frequency of corrective, surveillance-guided procedures performed. METHODS: Multicenter, prospective, observational study that includes consecutive hemodialysis patients receiving therapy from native arteriovenous fistulae (AVF) or grafts (AVG). Participants were assigned to a routine VA Color Doppler ultrasound surveillance (DUS) protocol from January 2019 to December 2021. Patients were referred for corrective procedures (endovascular or surgical) based on clinical or DUS findings (pre-emptive procedures; PEP). Primary endpoint was the estimation of primary unassisted (PUP) and secondary patency (SP) rates. Secondary endpoints were the determination of the number and frequency of PEP and VA survival rates. RESULTS: In total, 223 patients with 243 VA (192 AVF and 51 AVG) were included. Access PUP and SP rates were 83% and 93% at 12 months, 75% and 88% at 24 months, and 72% and 83% at 36 months follow-up. Autologous fistulae PUP and SP were 89% and 96% at 12 months, 81% and 93% at 24 months, and 80% and 89% at 36 months, respectively. Graft PUP and SP were 56% and 80% at 12 months, 44% and 65% at 24 months, and 39% and 54% at 36 months, respectively. In total, 56 corrective procedures (38/56 PEP; 65.5%) were performed (0.13 procedures/year), of which 34 were in AVF patients (0.09 procedures/year) and 22 in AVG patients (0.40 procedures/year). Overall, 33 VA losses occurred (0.06 failures/year), 17 in AVF (0.04 failures/year), and 16 in AVG patients (0.20 failures/year). CONCLUSION: The use of DUS resulted in the timely diagnosis of dysfunction, satisfactory overall VA survival, and patency rates, with a low PEP frequency. Randomized controlled trials are required to establish the value of DUS surveillance on access patency and whether DUS-guided interventions could improve VA outcomes.
ABSTRACT
OBJECTIVE/BACKGROUND: To investigate the long-term outcomes after endovascular aneurysm repair (EVAR) in a real-world setting using the Endurant endograft (EG). METHODS: 184 EVAR candidates treated with the Endurant family EGs in a single vascular center were prospectively enrolled from January 2009 to December 2016. Kaplan-Meir estimates of long-term standardized primary and secondary outcome measures were performed. Per protocol, subgroup comparison analysis was performed in three groups: patients treated within instructions for use (in-IFU) vs patients treated outside IFU (outside-IFU), EVAR in patients receiving the Endurant proximal diameter 32 or 36 mm EG vs those receiving the <32 mm diameter EG and EVAR with various Endurant EG versions. RESULTS: The mean follow-up was 75.09 ± 37.9 months (range: 4.1-172 months). The median age of the patients was 72.96 ± 7.03 years (range: 55-88 years). A total of 177 patients were male (96.2%). Compliance with IFU was followed in 107 patients (58.2%). Overall survival was 69.5% and 48% at 5 and 8 years, respectively. Of the 102 all-cause deaths, 7 (6.9%) were aneurysm related. Six of these postimplant deaths occurred in patients presented with aneurysm rupture from type Ia or/and type Ib endoleak. At 5, 8, and 10 years of observation, freedom from aneurysm rupture, open surgical conversion, type I/III endoleak, any type of endoleak, aneurysm-related secondary intervention probabilities, and neck-related events were as follows: 98.1%, 95%, and 89.4%; 95.1%, 91.2%, and 85.7%; 93.6%, 87.3%, and 83.9%; 83.4%, 74%, and 70.9%; 89.8%, 76.7%, and 72%; and 96.3%, 90%, and 87.6%, respectively. Corresponding clinical success was 90%, 77.4%, and 68.4%, respectively. Patients treated outside-IFU had significantly higher risk of aneurysm rupture, open surgical conversion probability, occurrence of type I/III endoleak, and chance of reinterventions and lower clinical success probabilities compared with the in-IFU counterparts at 5 and 8 years. This statistical difference remained when type Ia endoleak or endoleak of any type was considered independently. In addition, it was stronger in patients having extreme anatomic boundaries (>1 hostile anatomic condition), when aneurysm-related death, aneurysm rupture, and clinical success at 5 years were considered. Overall proximal migration and limb occlusion were recorded in 1.1% and 4.9% of the patients, respectively. Overall reintervention rate was 17.4%. An increase in aneurysm sac diameter was observed in 12.5% of patients and was not related to IFU status. The Endurant version or the proximal EG diameter had no significant association with the chance of any complication or adverse event. CONCLUSIONS: The data confirmed the durability of the Endurant EG, achieving promising long-term outcomes in a real-world setting. However, its positive performance must be interpreted with caution in patients treated off-label especially those with extreme anatomic boundaries. In this cohort, some of EVAR advantages might be lost in the late future. Further similar studies are warranted.

BACKGROUND: To provide a summary of the current state of research in English medical literature on circulating miRNAs as biomarkers for abdominal aortic aneurysm (AAA). Additionally, for the most commonly mentioned circulating miRNAs in the literature, to attempt a documentation of the biological mechanisms underlying their role in AAA development. METHODS: A literature search was undertaken in the MEDLINE database. Only reports that involved peripheral blood samples (whole blood, plasma, and serum) were included. The following terms were used in combination: microrna, mirna, AAA, human, circulating, plasma, serum, endovascular, and endovascular aneurysm repair (EVAR). RESULTS: A total of 25 reports, published from 2012 to 2022 were included with a total of 1,259 patients with AAA, predominantly men (N = 1,040, 90%). Six of these reports recruited healthy donors who underwent ultrasound screening for AAA as control samples. The majority of studies were undertaken in plasma samples and the most preferred microRNA profiling method was real - time quantitative polymerase chain reaction (qRT-PCR). The following 9 miRNAs (out of a total of 76) were studied in more than 2 references: miR-145, miR-24, miR-33, miR-125, let-7, miR-15, miR-191, miR-29, and miR-133. CONCLUSIONS: The 9 miRNAs described in this study, are implicated in known pathogenetic mechanisms of AAA, such as atherosclerosis, vascular smooth muscle cell (VSMCs) phenotype switch and apoptosis, vascular inflammation, extracellular matrix (ECM) degradation, and lipid metabolism. Identifying disease-specific miRNAs, in combination with other clinical parameters, as indicators of AAA, is crucial for early diagnosis as well as follow-up of AAAs. For future research on miRNAs as AAA biomarkers, strict case and control group definitions, sample acquisition protocols, and miRNA expression profiling techniques are warranted.

OBJECTIVES: The catheter-directed foam sclerotherapy (FS) and the suggested perivenous tumescent application for great saphenous vein (GSV) diameter reduction are suggested to improve technical and clinical results; yet, their use is reported rather indiscriminately. Our aim is to introduce an algorithm categorising the use of technical modalities accompanying ultrasound-guided FS of the GSV and present the technical efficacy of FS through a 5 F × 11 cm sheath placed at the knee level. METHODS: Representative cases of GSV insufficiency were chosen to describe our methodology. RESULTS: Sole sheath-directed FS can achieve complete GSV occlusion proximally at a level comparable to the catheter-directed technique. We apply perivenous 4°C cold tumescent to GSV >6 mm even in the standing position to ensure diameter reduction of the proximal GSV as close to the saphenofemoral junction. We use long catheters only to overcome large varicosities above the knee level that could otherwise compromise the adequate foam infusion from the sheath tip. When GSV insufficiency extends along the entire limb and severe skin lesions preclude the antegrade distal catheterisation, the sheath-directed FS in the thigh can be concomitantly combined with retrograde FS from catheterisation just below the knee. CONCLUSIONS: A topology-oriented methodology with sheath-directed FS is technically feasible and avoids indiscriminate use of more complex modalities.
ABSTRACT
The Ovation Alto design repositions the maximum diameter of the proximal sealing ring at 7 mm below the lowermost renal artery. Although it has been introduced to address abdominal aortic aneurysms with short necks ≥7 mm, we present further applications of Alto in other neck irregularities, presenting four representative challenging cases with a short, wide, and conical neck, as well a juxtarenal aneurysm. At 1-month follow-up, there was 100% technical and clinical success.
ABSTRACT
INTRODUCTION: The Altura aortic endograft for the treatment of abdominal aortic aneurysms (AAA) consists of two separate components with a proximal double D-shaped design. The braided endoskeleton of the endograft is attached only at the proximal and distal ends of the inner surface of the fabric resulting in adjustable length of the Altura components. To ensure optimal orientation and sealing, the design of Altura permits collapse, readjustment, and deployment of the repositioned D-shaped endografts. AREAS COVERED: Since this new endograft design by Lombard presents unique characteristics, the aim of this article is to present its unique structure and deployment method and discuss its applicability, indications and associated concerns. EXPERT OPINION: The Altura endograft revolutionizes the mechanism of infrarenal sealing by containing no main body at all. This feature allows ideal treatment of AAA with considerable offset of the renal arteries and permits also relining in cases of failing endografts or in cases where the short length of existing structures precludes deployment of conventional bifurcated endografts.

Although rare, pseudoaneurysms (PAs) of the palmar arch are mostly considered benign. However, they can cause severe complications if left untreated or misdiagnosed. There are a few data on traumatic PAs of the palmar arch, particularly those most commonly caused by penetrating hand injuries. However, PAs caused by blunt trauma are more insidious in onset, presenting as a painful pulsatile mass in the palmar area of the hand, and require prompt diagnosis and management to avoid catastrophic sequelae. Our case is the first study to describe a patient with traumatic PA of the palmar arch caused by blunt trauma that was treated with surgical reconstruction and venous bypass interposition.
ABSTRACT
OBJECTIVE: Use of classic bifurcated endografts for relining of bifurcated aortic bypass grafts with aneurysms is usually precluded by the short distance between the lowermost renal artery and the aneurysmatic bifurcation, rendering their management challenging. METHODS: We present the use of the Altura endograft in a case of a 75-year old male with large anastomotic aneurysms in the proximal and the left iliac amastomosis of a bifurcated aortic bypass graft. The Altura endograft consists of two separate components with a proximal D-shaped design. Its braided nitinol endoskeleton is attached only at the proximal and distal ends of the inner surface of the polyester fabric and results in adjustable lengths of the components according to the vessel diameters where they are deployed. RESULTS: A 24 mm Altura sealed successfully at the native infarenal aortic segment covering the entire distance between the lowermost renal artery and the upper end of external iliac artery, providing successful exclusion of the aneurysms. No iliac extensions were used. The completion angiography showed no endoleaks. CONCLUSIONS: The unique design of Altura makes it ideal for treatment of anastomotic aneurysms of bifurcated bypass grafts, overcoming anatomic limitations. To the best of our knowledge, this is the first report addressing this crucial issue.
ABSTRACT
Diabetic foot ulcers remain difficult to heal, especially in the setting of peripheral arterial disease (PAD). Vascular surgeons are very important members of the multidisciplinary foot care team. To make the most of their potential, adequate education of vascular trainees on diabetic PAD remains a priority. This should include not only endovascular therapies but also open surgical approaches. Evaluation of trainees' skills, as well as of the educational program itself, is also desirable. Finally, simulation-based training may prove a useful educational tool.
ABSTRACT
OBJECTIVE: The aim of the Endurant for Challenging Anatomy: Global Experience (EAGLE) registry is to evaluate prospectively the technical and clinical success rate of a stentgraft used in patients with challenging neck anatomy outside the instructions for use (IFU) but within objective anatomical limits. METHODS: This was a prospective, international, multicentre, observational study. From 1 February 2012 to 1 September 2017, patients with an abdominal aortic aneurysm with a challenging infrarenal neck that were deemed suitable for endovascular aneurysm repair were included prospectively at 23 European centres. Patients were distributed by anatomy into three groups: short neck (SN; infrarenal neck 5 - 10 mm in combination with suprarenal angulation [α] ≤ 45° and infrarenal angulation [ß] ≤ 60°); medium neck (MN; infrarenal neck 10 - 15 mm with α ≤ 60° and ß 60° - 75° or α 45°- 60° and ß ≤ 75°; and long angulated neck (LN; infrarenal neck ≥ 15 mm with α ≤ 75° and ß 75°- 90° or α 60°- 75° and ß ≤ 90°. All computed tomography scans were reviewed by an independent core laboratory. Primary outcomes were technical and clinical success. Secondary endpoints were peri-operative major adverse events, all cause mortality, aneurysm related mortality, endoleaks, migration, and secondary intervention. RESULTS: One hundred and fifty patients (81.3% male) were included (SN = 55, MN = 16, LN = 79). The median follow up was 36 ± 12.6 months. In the overall cohort, the technical success rate was 93.3%. Estimated freedom from aneurysm related death was 97.3% at three years. Freedom from secondary interventions was 84.7% at three years. Estimated clinical success was 96.0%, 90.8%, and 83.2% at 30 days, one year, and three years, respectively. Estimated freedom from all cause mortality, late type IA endoleak, and migration at three years was 75.1%, 93.7%, and 99.3%, respectively. CONCLUSION: The early and midterm results of the EAGLE registry show that endovascular repair with the Endurant stentgraft in selected patients with challenging infrarenal neck anatomy yields results in line with large "real world" registries. Long term results are awaited for more definitive conclusions.
