Sex-specific differences in alive hospital discharge following infrarenal abdominal aortic aneurysm repair.

Background And Aims: A longer time to alive hospital discharge following infrarenal abdominal aortic aneurysm (AAA) repair is associated with reduced patient-satisfaction and increased length of stay, hospital-acquired deconditioning, infection and costs. This study investigated sex-specific differences in, and drivers of, the rate of alive hospital discharge.

Methods: Examination of UK National Vascular Registry (UK NVR), 2014-2019 and Swedish National Patient Registry (SE NPR) elective AAA patients, 2010-2018, for endovascular (EVAR) or open (OAR) aneurysm repair.

Editor's Choice - A Core Outcome Set for Intact Abdominal Aortic Aneurysm Repair.

Objective: Technology and advances in clinical care have changed the management of abdominal aortic aneurysms (AAAs) but the clinical effectiveness of continuing advances needs to be assessed. To facilitate rapid synthesis of new evidence and improve stakeholder representation, including patients, the concept of core outcome sets (COS) has been developed. COS, reflecting the needs of all stakeholders, have been established across several surgical specialties.

Editor's Choice -- European Society for Vascular Surgery (ESVS) 2024 Clinical Practice Guidelines on the Management of Abdominal Aorto-Iliac Artery Aneurysms.

Objective: The European Society for Vascular Surgery (ESVS) has developed clinical practice guidelines for the care of patients with aneurysms of the abdominal aorta and iliac arteries in succession to the 2011 and 2019 versions, with the aim of assisting physicians and patients in selecting the best management strategy.

Methods: The guideline is based on scientific evidence completed with expert opinion on the matter. By summarising and evaluating the best available evidence, recommendations for the evaluation and treatment of patients have been formulated.

Assessment of Subclinical Atherosclerosis in Asymptomatic People In Vivo: Measurements Suitable for Biomarker and Mendelian Randomization Studies.

Background: One strategy to reduce the burden of cardiovascular disease is the early detection and treatment of atherosclerosis. This has led to significant interest in studies of subclinical atherosclerosis, using different phenotypes, not all of which are accurate reflections of the presence of asymptomatic atherosclerotic plaques. The aim of part 2 of this series is to provide a review of the existing literature on purported measures of subclinical disease and recommendations concerning which tests may be appropriate in the prevention of incident cardiovascular disease.

Pathogenesis and management of abdominal aortic aneurysm.

Abdominal aortic aneurysm (AAA) causes ∼170 000 deaths annually worldwide. Most guidelines recommend asymptomatic small AAAs (30 to <50 mm in women; 30 to <55 mm in men) are monitored by imaging and large asymptomatic, symptomatic, and ruptured AAAs are considered for surgical repair. Advances in AAA repair techniques have occurred, but a remaining priority is therapies to limit AAA growth and rupture.

Sex-specific differences in the standard of care for infrarenal abdominal aortic aneurysm repair, and risk of major adverse cardiovascular events and death.

Background: This study investigated whether sex-specific differences in preoperative/perioperative standard of care (SOC) account for disparity in outcomes after elective infrarenal abdominal aortic aneurysm repair.

Methods: This was a retrospective cohort study of elective infrarenal abdominal aortic aneurysm repairs (2013-2020) using depersonalized patient-level National Vascular Registry data. SOC was defined for waiting times, preoperative assessment (multidisciplinary/anaesthetic review), cardiovascular risk prevention, and perioperative medication.

Shared Decision Making and the Management of Intact Abdominal Aortic Aneurysm: A Scoping Review of the Literature.

Objective: The aim of this study was to summarise the current knowledge of shared decision making (SDM) in patients facing a treatment decision about an intact abdominal aortic aneurysm (AAA), and to identify where further evidence is needed.

Data Sources: MEDLINE, Embase, and the Cochrane Library were searched on 18 July 2021. An updated search was run on 31 May 2022 for relevant studies published from 1 January 2000 to 31 May 2022.

Developing Core Outcome Sets for Vascular Conditions Across Europe, Not as Easy as It Sounds.

Introduction: Most of the outcomes reported in the literature have been chosen by doctors, constituting "traditional" outcome measures such as mortality and re-intervention. Some of the key outcome measures important to patients, families, health providers and other stakeholders may have been overlooked. Core outcome sets, consisting of 6-15 outcomes, can improve representation of all key stakeholders, standardise outcome reporting, and improve future ability to pool results.

Systematic Reviews of the Literature Are Not Always Either Useful Or the Best Way To Add To Science.

Systematic reviews are becoming more popular as a way of doing research; however, not all systematic reviews are clinically useful and sometimes another type of review (scoping, topical, or critical) would be of greater value to the clinical and scientific community. The different types of review and their use are described, illustrated by examples relevant to vascular surgery.

Low Shear Stress at Baseline Predicts Expansion and Aneurysm-Related Events in Patients With Abdominal Aortic Aneurysm.

Background: Low shear stress has been implicated in abdominal aortic aneurysm (AAA) expansion and clinical events. We tested the hypothesis that low shear stress in AAA at baseline is a marker of expansion rate and future aneurysm-related events.

Methods: Patients were imaged with computed tomography angiography at baseline and followed up every 6 months >24 months with ultrasound measurements of maximum diameter.

Editor's Choice - Systematic Review and Meta-Analysis of Sex Specific Differences in Adverse Events After Open and Endovascular Intact Abdominal Aortic Aneurysm Repair: Consistently Worse Outcomes for Women.

Objective: Previously, reports have shown that women experience a higher mortality rate than men after elective open (OAR) and endovascular (EVAR) repair of abdominal aortic aneurysm (AAA). With recent improvements in overall AAA repair outcomes, this study aimed to identify whether sex specific disparity has been ameliorated by modern practice, and to define sex specific differences in peri- and post-operative complications and pre-operative status; factors which may contribute to poor outcome.

Methods: This was a systematic review, meta-analysis, and meta-regression of sex specific differences in 30 day mortality and complications conducted according to PRISMA guidance (Prospero registration CRD42020176398).

Towards a Core Outcome Set for Abdominal Aortic Aneurysm: Systematic Review of Outcomes Reported Following Intact and Ruptured Abdominal Aortic Aneurysm Repair.

Objective: To encompass the needs of all stakeholders and allow effective data synthesis from trials, registries, and other studies; a core outcome set for infrarenal abdominal aortic aneurysm (AAA) repair is needed. In this first stage, the aim was to report the range, frequency, and time of pre-specified outcomes reported following AAA repair.

Data Sources: Medline, Embase, and CENTRAL databases 2010 - 2019 were searched using ProQuest Dialog™.

Surgery for small asymptomatic abdominal aortic aneurysms.

Background: An abdominal aortic aneurysm (AAA) is an abnormal ballooning of the major abdominal artery. Some AAAs present as emergencies and require surgery; others remain asymptomatic. Treatment of asymptomatic AAAs depends on many factors, but the size of the aneurysm is important, as risk of rupture increases with aneurysm size.

Analysis of the Differences Between the ESVS 2019 and NICE 2020 Guidelines for Abdominal Aortic Aneurysm.

Objective: The aim was to understand why two recently published guidelines for the diagnosis and management of patients with abdominal aortic aneurysm, the National Institute for Health and Care Excellence (NICE) 2020 guidelines and the European Society for Vascular Surgery (ESVS) 2019 guidelines, have discordant recommendations in several important areas.

Methods: A review of the approach, methodology, and evidence used by the two guideline committees was carried out to understand potential reasons for their differing recommendations in their two final published guidelines.

Results: NICE guidelines use a multidisciplinary committee to address a limited number of prospectively identified questions, using rigorous methods heavily reliant on evidence from randomised controlled trials (RCTs) supported by in house economic modelling, with the purpose of providing the best, cost-effective health care in the UK in 46 main recommendations.
