Inflow Artery Aneurysmal Degeneration After Long Term Native Arteriovenous Fistula for Haemodialysis.

Objective: Inflow arterial aneurysms are a rare but serious complication after long term arteriovenous fistulae (AVF), probably due to arterial wall remodelling after an increase in flow and shear stress, and kidney transplantation with immunosuppressive therapy. This study aimed to describe the outcomes of surgical treatment and long term follow up in a large cohort.

Methods: This prospective cohort study collected data from patients with a true inflow artery aneurysm after AVF creation that was surgically repaired between 2010 and 2022.

Outcomes After Endovascular Aortic Intervention in Patients With Connective Tissue Disease.

Importance: Endovascular treatment is not recommended for aortic pathologies in patients with connective tissue diseases (CTDs) other than in redo operations and as bridging procedures in emergencies. However, recent developments in endovascular technology may challenge this dogma.

Objective: To assess the midterm outcomes of endovascular aortic repair in patients with CTD.

European Expert Opinion on Infrarenal Sealing Zone Definition and Management in Endovascular Aortic Repair Patients: A Delphi Consensus.

Purpose: The purpose of the study was to provide a consensus definition of the infrarenal sealing zone and develop an algorithm to determine when and if adjunctive procedure(s) or reintervention should be considered in managing patients undergoing endovascular aortic repair (EVAR) for infrarenal abdominal aortic aneurysm (AAA).

Methods: A European Advisory Board (AB), made up of 11 vascular surgeons with expertise in EVAR for AAA, was assembled to share their opinion regarding the definition of preoperative and postoperative infrarenal sealing zone. Information on their current clinical practice and level of agreement on proposed reintervention paths was used to develop an algorithm.

Total endovascular treatment for thoraco-abdominal aortic aneurysm in a patient with Behçet's disease: Case report and literature review.

Introduction: To report total endovascular treatment for a rare case of Crawford extent IV thoraco-abdominal aortic aneurysm (TAAA) using custom-designed branched device in a patient with Behçet's disease.

Methods: A 50 years' old man with history of BD was accidentally diagnosed Crawford extent IV TAAA during computed tomography follow-up after left nephrectomy of renal carcinoma. The aneurysm extended from descending aorta to right common iliac artery with a maximum diameter of 6.

Reducing residual thrombotic risk in patients with peripheral artery disease: impact of the COMPASS trial.

Patients with peripheral artery disease (PAD) are at a high risk not only for the classical cardiovascular (CV) outcomes (major adverse cardiovascular events; MACE) but also for vascular limb events (major adverse limb events; MALE). Therefore, a comprehensive approach for these patients should include both goals. However, the traditional antithrombotic approach with only antiplatelet agents (single or dual antiplatelet therapy) does not sufficiently reduce the risk of recurrent thrombotic events.

Climatic influence on the risk of abdominal aortic aneurysm rupture.

Our aim is to examine the effects of climatic conditions on the incidence of ruptured abdominal aortic aneurysms (rAAA) in Catalonia, Spain. We combined clinical data from the Public Health official registries in Catalonia, Spain (HD-MBDS) of all rAAA with local climatic data obtained from the closest meteorological station (69 stations, National Meteorological Service: MeteoCat) from 2008 to 2017. We analyzed the median, maximum, minimum, and variability of atmospheric pressure (hPa) and air temperature (°C), solar irradiation (MJ/m), humidity (%), accumulated precipitation (mm), median wind, and maximum flaw direction and velocity (°, m/s), recorded on the days of events, the previous day, and mean results for 3, 7, and 30 days before, as well as seasonality.

Surgical Decision Making in Uncomplicated Type B Aortic Dissection: A Survey of Australian/New Zealand and European Surgeons.

Objective: There is controversy about the role of pre-emptive thoracic endovascular aortic repair (TEVAR) in uncomplicated type B aortic dissection (TBAD). The aim was to understand expert opinions and the factors influencing decision making.

Methods: In 2018, surgeons from Australia/New Zealand (ANZ) and Europe (EUR) were contacted to participate in an online survey which comprised questions about preferences for pre-emptive TEVAR, followed by five case scenarios, and two ranking questions for anatomical and technical risk factors respectively.

Residual risk reduction opportunities in patients with chronic coronary syndrome. Role of dual pathway inhibition.

Introduction: In this review, the role of the rivaroxaban-plus-aspirin approach (dual pathway inhibition - DPI) in patients with chronic coronary syndrome (CCS) and to perform practical recommendations about its use was updated.

Areas Covered: The contents of this review were proposed in an expert meeting. To identify relevant articles, a systematic search of Medline/Embase was performed (to July 2019), using the key words 'rivaroxaban', 'vascular dose', 'COMPASS' and 'coronary artery disease' in the search strategy.

Improved Remodeling With TEVAR and Distal Bare-Metal Stent in Acute Complicated Type B Dissection.

Background: The ASSIST (A multicentre Study in Survivors of type B aortic dissection undergoing Stenting) study compared both 1-year outcomes and evolution of true and false lumen (eg, remodeling) in patients with complicated type B aortic dissection subjected to thoracic endovascular aortic repair (TEVAR) with distal true lumen scaffolding by self-expanding nitinol open stent in comparison with TEVAR alone.

Methods: The ASSIST study was a multicenter prospective single-arm study comparing clinical and imaging data from 39 consecutive patients (59.4 ± 13 years of age) who received TEVAR and the JOTEC E-XL open stent with data from matched control subjects treated with TEVAR alone based on 1:1 propensity score matching.

FEVAR/BEVAR have limitations and do not always represent the preferred option for juxtarenal reconstruction.

Following the definition given by the recent ESVS guidelines, juxtarenal abdominal aortic aneurysm (JAAA) is defined as an aneurysm extending up to but not involving the renal arteries, necessitating suprarenal aortic clamping for open surgery, i.e. a short neck (<10 mm).

Influence of On-Call Vascular Surgery Team and Off-Hour Effect on Survival after Ruptured Abdominal Aortic Aneurysm.

Background: Ruptured abdominal aortic aneurysms (rAAAs) represent a life-threatening emergency and carry a high community and in-hospital mortality, despite treatment and protocol advances. Identifying prognostic factors like the presence of on-call vascular surgery teams at first hospital admissions or times of hospital admissions can modify hospital protocols and mechanisms to ameliorate general outcomes. The aim of this study is to analyze the influence of on-call vascular surgery teams and off-hour admissions on survival after rAAAs in Catalonia, Spain.

Review of serum biomarkers in carotid atherosclerosis.

Background: Carotid artery atherosclerotic stenosis is a preventable major cause of stroke, but there is still a need for definition of high-risk plaque in asymptomatic patients who might benefit from interventional therapies. Several image markers are recommended to characterize unstable plaques. The measurement of serum biomarkers is a promising method to assist in decision making, but the lack of robust evidence in the carotid environment burdens their potential as a standard of care.

Research methodology and practical issues relating to the conduct of a medical device registry.

Background: The postmarket research goal is to assess "generalizability" or "external validity" to see if the early results of clinical trials with investigational devices are reproducible in everyday practice in the real world and the longer term. Registries have an important but ambivalent role in achieving this goal.

Methods: Although registries are common, in practice they follow the regulatory processes that appear designed primarily for pharmaceutical clinical trials and confirmatory studies.
