Impact of Age Differences in Chronic Limb-Threatening Ischemia Outcomes in Octogenarians.

Background: The aging population is a growing challenge for healthcare services and as such multimorbidity and associated aging are the focus of research programs. Chronic limb-threatening ischemia (CLTI) in the older patient is perceived to be associated with high morbidity and mortality but a potentially contentious area with limited evidence.

Methods: Retrospective review of all consecutive CLTI admissions to a UK tertiary vascular during 2020.

Outcomes Following Vascular and Endovascular Procedures Performed During the First COVID-19 Pandemic Wave.

Objective: The first COVID-19 pandemic wave was a period of reduced surgical activity and redistribution of resources to only those with late stage or critical presentations. This Vascular and Endovascular Research Network COVID-19 Vascular Service (COVER) study aimed to describe the six-month outcomes of patients who underwent open surgery and or endovascular interventions for major vascular conditions during this period.

Methods: In this international, multicentre, prospective, observational study, centres recruited consecutive patients undergoing vascular procedures over a 12-week period.

Evaluating current acute aortic syndrome pathways: Collaborative Acute Aortic Syndrome Project (CAASP).

Background: Diagnosis of acute aortic syndrome is challenging and associated with high perihospital mortality rates. The study aim was to evaluate current pathways and understand the chronology of acute aortic syndrome patient care.

Method: Consecutive patients with acute aortic syndrome imaging diagnosis between 1 January 2018 and 1 June 2021 were identified using a predetermined search strategy and followed up for 6 months through retrospective case note review.

Evaluating pharmacological THRomboprophylaxis in Individuals undergoing superficial endoVEnous treatment across NHS and private clinics in the UK: a multi-centre, assessor-blind, randomised controlled trial-THRIVE trial.

Introduction: Endovenous therapy is the first choice management for symptomatic varicose veins in NICE guidelines, with 56-70 000 procedures performed annually in the UK. Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a known complication of endovenous therapy, occurring at a rate of up to 3.4%.

Understanding the current acute aortic syndrome (AAS) pathways-The Collaborative Acute Aortic Syndrome Project (CAASP) protocol.

Background: Acute aortic syndrome (AAS) is an emergency associated with high peri-hospital mortality rates. Variable clinical presentation makes timely diagnosis challenging and such delays in diagnosis directly impact patient outcomes.

Aims And Objectives: The aims of the Collaborative Acute Aortic Syndrome Project (CAASP) are to characterise and evaluate the current AAS pathways of a cohort of hospitals in the UK, USA and New Zealand to determine if patient outcomes are influenced by the AAS pathway (time to hospital admission, diagnosis and management plan) and demographic, social, geographic and patient-specific factors (clinical presentation and comorbidities).

Sarcopenia and Sarcopenic Obesity on Body Composition Analysis is a Significant Predictor of Mortality in Severe Acute Pancreatitis: A Longitudinal Observational Study.

Background: The prevalence and impact of sarcopenia and sarcopenic obesity noted on body composition analysis in severe acute pancreatitis (SAP) is unknown. This study investigates the prevalence of sarcopenia at different timepoints and its effect on post-pancreatitis complications and mortality.

Methods: A prospective database of SAP admissions with organ failure at a single institution from 2015 to 2019 were analysed.

The Impact of Pre-Operative Anaemia on One Year Amputation Free Survival and Re-Admissions in Patients Undergoing Vascular Surgery for Peripheral Arterial Disease: a National Vascular Registry Study.

Objective: Anaemia is common among patients undergoing surgery, but its association with post-operative outcomes in patients with peripheral arterial disease (PAD) is unclear. The aim of this observational population based study was to examine the association between pre-operative anaemia and one year outcomes after surgical revascularisation for PAD.

Methods: This study used data from the National Vascular Registry, linked with an administrative database (Hospital Episode Statistics), to identify patients who underwent open surgical lower limb revascularisation for PAD in English NHS hospitals between January 2016 and December 2019.

Social deprivation does not impact on acute pancreatitis severity and mortality: a single-centre study.

Background And Aims: The incidence of acute pancreatitis (AP) is increasing in the UK. Patients with severe AP require a significant amount of resources to support them during their admission. The ability to predict which patients will develop multiorgan dysfunction remains poor leading to a delay in the identification of these patients and a window of opportunity for early intervention is missed.

Evaluating the feasibility and acceptability of an exercise and behaviour change intervention in socioeconomically deprived patients with peripheral arterial disease: The textpad study protocol.

This pilot randomised controlled trial aims to assess the feasibility and acceptability of a 12-week home-based telehealth exercise and behavioural intervention delivered in socioeconomically deprived patients with peripheral artery disease (PAD). The study will also determine the preliminary effectiveness of the intervention for improving clinical and health outcomes. Sixty patients with PAD who meet the inclusion criteria will be recruited from outpatient clinic at the Freeman Hospital, United Kingdom.

The adverse impact of pre-operative anaemia on survival following major lower limb amputation.

Introduction: Approximately 5000 major lower-limb amputations (MLLA) for PAD occur per-annum in the UK with clinical outcomes being poor for this high-risk cohort of patients. Existing evidence suggests that anaemic surgical patients have an increased 30-day mortality, but this has not been explored in the context of MLLA. Recent prioritization processes suggested that MLLAs are a target area for research into outcome improvement.

The persistent challenges faced by vascular surgery services during the UK coronavirus pandemic: a snapshot qualitative survey.

Introduction: The coronavirus (COVID-19) pandemic continues to affect the NHS. The Vascular and Endovascular Research Network (VERN) COvid Vascular sERvice (COVER) study has prospectively shown the significant global impact of the COVID-19 pandemic on vascular surgery. The aim of this study is to investigate the way in which this second wave has affected surgeons' ability to treat patients with urgent vascular conditions, using contemporaneous snapshot data from 30 UK vascular centres.

Social Deprivation and the Association With Survival Following Fenestrated Endovascular Aneurysm Repair.

Background: Social deprivation is associated with poor clinical outcomes. It is known to have an impact on length of stay and post-operative mortality across a number of other surgical specialties. This study evaluates the impact of social deprivation on outcomes following fenestrated endovascular aneurysm repair (FEVAR).

The PReliMinAry (Pain Relief in Major Amputation) Survey.

Objectives: Major Lower Limb Amputation (MLLA) is associated with significant peri- and post-operative pain and has been identified as a research priority by patient and healthcare groups. The PReliMinAry survey was designed to evaluate existing MLLA analgesia strategies; identifying areas of equipoise and informing future research.

Methods: A targeted multi-national, multi-disciplinary survey was conducted via SurveyMonkey® (October 5, 2020-November 3, 2020) and advertised via social media and society email lists.

Interventions for great saphenous vein incompetence.

Background: Great saphenous vein (GSV) incompetence, causing varicose veins and venous insufficiency, makes up the majority of lower-limb superficial venous diseases. Treatment options for GSV incompetence include surgery (also known as high ligation and stripping), laser and radiofrequency ablation, and ultrasound-guided foam sclerotherapy. Newer treatments include cyanoacrylate glue, mechanochemical ablation, and endovenous steam ablation.

Anaemia: A risk factor for death and adverse outcomes following surgery for acute lower limb ischaemia.

Introduction: Acute limb ischaemia (ALI) forms a significant part of the vascular surgery workload and carries with it high rates of morbidity and mortality. Anaemia is also common amongst vascular surgical patients and has been linked with poor outcomes in some subgroups. We aimed to assess the frequency of anaemia in patients with ALI and its impact on survival and complications following revascularisation to help direct future efforts to optimise outcomes in this patient group.

Dissecting the Management and Outcomes of Thoracic Aortovascular Disease During the COVID-19 Pandemic.

Objective: The COVID-19 pandemic has forced the cancellation of planned surgery and led to significant surgical service reductions. Early intervention in aortovascular disease is often critical and cannot be deferred despite these reductions. There is urgent need to evaluate the provision and outcomes of thoracic aortovascular intervention during the peak of the pandemic.

Sarcopenia in Patients Undergoing Lower Limb Bypass Surgery is Associated with Higher Mortality and Major Amputation Rates.

Background: Sarcopenia is adversely associated with survival in several diseases. Vasculopathy is often associated with multimorbidity and consequent deconditioning with poor long-term outcomes. This study examined the impact of sarcopenia on clinical outcome in patients with and without critical limb-threatening ischaemia who underwent infrainguinal bypass surgery.

Editor's Choice - Systematic Review and Meta-Analysis of Wound Adjuncts for the Prevention of Groin Wound Surgical Site Infection in Arterial Surgery.

Objective: Groin incision surgical site infections (SSIs) following arterial surgery are common and are a source of considerable morbidity. This review evaluates interventions and adjuncts delivered immediately before, during, or after skin closure, to prevent SSIs in patients undergoing arterial interventions involving a groin incision.

Data Sources: MEDLINE, EMBASE, and CENTRAL databases were searched.

Study protocol for COvid-19 Vascular sERvice (COVER) study: The impact of the COVID-19 pandemic on the provision, practice and outcomes of vascular surgery.

Background: The novel Coronavirus Disease 2019 (COVID-19) pandemic is having a profound impact on global healthcare. Shortages in staff, operating theatre space and intensive care beds has led to a significant reduction in the provision of surgical care. Even vascular surgery, often insulated from resource scarcity due to its status as an urgent specialty, has limited capacity due to the pandemic.

Outcomes of Vascular and Endovascular Interventions Performed During the Coronavirus Disease 2019 (COVID-19) Pandemic.

Objective: The aim of the COVER Study is to identify global outcomes and decision making for vascular procedures during the pandemic.

Background Data: During its initial peak, there were many reports of delays to vital surgery and the release of several guidelines advising later thresholds for vascular surgical intervention for key conditions.

Methods: An international multi-center observational study of outcomes after open and endovascular interventions.

Preoperative anaemia management in patients undergoing vascular surgery.

CAVIAR is a multicentre prospective stepped observational study encompassing 160 patients undergoing vascular intervention. The aim was to identify whether it was feasible to establish a preoperative anaemia pathway and, if so, the efficacy of intravenous iron for treatment of preoperative anaemia. Large barriers prevented implementation of an intravenous iron pathway, with only ten patients receiving intravenous iron and a small increase in haemoglobin level (mean 5·7 (95 per cent c.
