Introduction: Critical limb ischemia (CLI) in diabetic patients is defined by non-healing foot ulcer or rest pain for more than 2 weeks with ankle pressure of less than 40 mmHg. The SVS WIfI classification system stratifies CLI on the basis of perfusion, extent of wound and superadded infection to provide a composite score which guides further management and predicts final prognosis OBJECTIVE: The aim of the study was to use the SVS WIfI scoring system to predict the need for early revascularization versus early amputation depending on the composite WIfI score at presentation., Methodology: This was a retrospective observational study. Data was collected on patients admitted with CLI, in the last 2 years, to calculate composite WIfI score. The WIfI categories according to risk of limb loss were identified with endpoint being major or minor amputation., Results: Among the 87 patients reviewed, 35 patients (40%) required major amputation, and 29 of those underwent vascular intervention (83%) as part of their care. Median age of the cohort was 72 and 71% were male patients. Comparative analysis between major amputations and minor amputation showed the median score on initial clinical presentation to be 7 in major amputation and 5 in minor amputations (p < 0.0001)., Conclusion: The composite WIFi score (a summation of the Wound, Ischaemia, and Infection sub-scores) was a good predictor of need for an amputation WIfI scoring system is a useful tool and should be used early in the management of infected ischaemic limbs., Competing Interests: Declaration of competing interest The authors declare that there is no conflict of interest., (Copyright © 2022 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Objective: A systematic review and meta-analysis was performed to determine the role of thromboprophylaxis in the prevention of venous thromboembolism in patients undergoing varicose vein interventions., Methods: PUBMED, EMBASE and Web of Science were searched for comparative studies of patients undergoing varicose vein interventions and received either thromboprophylaxis or no thromboprophylaxis. Data were collected on the number of thrombotic events including deep vein thrombosis (DVT), pulmonary embolism (PE) and endothermal heat-induced thrombosis (EHIT) as well as bleeding events. The primary outcomes for the meta-analysis were the risk of all thrombotic events, risk of DVT and risk of bleeding. Pooled risk ratios were calculated using random effects modelling., Results: Eight studies (6479 participants) were included. The use of thromboprophylaxis reduces the risk of all thrombotic events (Pooled risk ratio = 0.63, 95% Confidence interval [CI], 0.04-10.43) and the risk of DVT (Pooled risk ratio = 0.59, 95% CI, 0.08-4.60) with no increased risk of bleeding (Pooled risk ratio = 0.66, 95% CI, 0.06-7.21]. Rivaroxaban has similar efficacy in the prevention of DVT compared to Fondaparinux in patients undergoing endovenous ablation of varicose veins (Pooled risk ratio = 0.68, 95% CI, 0.06-7.41). An extended course of thromboprophylaxis reduces the risk of developing DVT compared to a short course (Pooled risk ratio = 1.40, 95% CI, 0.44-4.46). However, the two studies reporting on the duration of thromboprophylaxis did not stratify patients according to their risk of developing venous thromboembolism., Conclusion: The use of thromboprophylaxis in patients undergoing varicose vein interventions reduces the risk of venous thromboembolism with no significant increase in the risk of bleeding. However, the included studies were underpowered with high to moderate risk of bias. Therefore, more randomised controlled trials with a large sample size are needed in order to provide high quality evidence for clinical practice., Competing Interests: Declaration of competing interest None., (Copyright © 2022 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Introduction: Peripheral arterial disease (PAD) is a growing public health burden. The development and progression of PAD is influenced by vascular risk factor management and lifestyle changes. However, public awareness of PAD is low compared with other conditions such as heart disease and stroke, which have been the subject of widespread public health campaigns. This study aimed to determine current levels of PAD awareness among hospital patients., Methods: This cross-sectional, tertiary hospital-based, descriptive study was conducted over 6 months in 2019. Two investigators administered the survey in face-to-face interviews to patients attending 3 different hospital-based settings including vascular clinics (VC), cardiology clinics (CVC), and Emergency Department (ED)., Results: A total of 150 patients were interviewed. Participants demonstrated low overall awareness of vascular disease (32% PAD and 21% AAA) compared to cardiovascular disease including stroke (71%) and myocardial infarction (63%). Awareness of PAD was higher in vascular patients (51%) compared to CVC and ED patients (p=<0.01). Of the total population, 77% and 71% identified the contributory role of smoking and limited exercise to the development of PAD respectively. VC patients were more informed of intermittent claudication (78%) and amputation (80%) (p < 0.01) compared to CVC and ED patients., Conclusion: In the global drive to reduce vascular morbidity, this study highlights the poor knowledge of PAD among the public. In addition, there is poor awareness about the incidence, risk factors and complications of PAD. These results highlight the need for accessible and easily understood information regarding PAD in both the clinic setting and public health campaigns., (Copyright © 2021 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Introduction: Endovascular aneurysm repair (EVAR) is a comparatively less invasive technique than open repair (OR). Debate remains with regard to the benefit of EVAR for patients with ruptured abdominal aortic aneurysm (RAAA). We sought to evaluate and report outcomes of EVAR for RAAA in an Irish tertiary vascular referral centre., Methods: Patients undergoing emergency surgery for ruptured or symptomatic AAA were identified from theatre logbooks and HIPE database. Retrospective chart review was undertaken. Data were exported to IBM SPSS version 21 for statistical analysis with p < 0.05 considered significant., Results: A total of 41 patients underwent surgery for RAAA. The mean age was 74 years old with a range from 55 to 89 years. The majority (n = 25, 61%) were baseline American Society of Anaesthesiology (ASA) grade 3-4. Of these 56% underwent EVAR with the remaining 44% repaired open. Mortality rate in those undergoing emergency EVAR was 34.8%, compared with 38.9% in those undergoing open surgery. This difference was not statistically significant. The mean overall length of stay was 13 days. With regard to prognostic indicators of patient outcome, increasing patient age was noted to be significantly associated with increased mortality (p = 0.013), as was increased ASA score at time of surgery (p = 0.029)., Conclusions: Mortality rates in those undergoing EVAR for RAAA are comparable with those undergoing open repair. Increasing age and ASA score are significant predictors of mortality in patients with RAAA undergoing intervention., (Copyright © 2015 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Background: Venous leg ulcers affect 1-3% of adults with a significant economic impact, utilizing 1% of annual healthcare budgets in some western European countries., Objectives: To determine the effects of intervention for incompetent superficial veins on ulcer healing and recurrence in patients with active or healed venous ulcers., Search Methods: In October 2014, we searched Medline, CINAHL, EMBASE, Scopus, the Cochrane library and Web of Science without date or language restriction for relevant randomized or observational studies. Bibliographies of included studies were also searched for additional studies., Selection Criteria: Observational studies or randomized controlled trials comparing intervention for varicose veins with compression therapy alone for venous leg ulcers were eligible. In addition, studies compared open to endovenous therapy for varicose veins in patients with leg ulcers and those compared treating saphenous and perforating veins to treating saphenous veins only were also included. Studies had to report at least one ulcer-related outcome (healing rate, recurrence or time to healing)., Data Collection and Analysis: Details of potentially eligible studies were extracted and summarized using a data extraction table. Data extraction and quality assessment were performed independently by two review authors, and any disagreements resolved by consensus or by arbitration of a third author., Results: Intervention for superficial venous reflux improved ulcer healing (risk ratio = 1.11 [1.00, 1.22], 95% CI, p = 0.04) and reduced recurrence (risk ratio = 0.48 [0.32, 0.67], 95% CI, p < 0.0001) compared to compression alone, with low level of evidence., Conclusion: This review confirmed that the evidence for a beneficial effect of endovenous and open surgery for varicose vein in venous leg ulcer is at beast weak. A well-structured RCT is required to investigate the role of endovenous ablation of incompetent superficial veins in improving venous leg ulcer outcomes., (Copyright © 2016 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Objectives: The number of operations performed per surgeon is thought to determine the quality of carotid endarterectomy (CEA) surgery. The advent of carotid artery stenting (CAS) threatens to reduce the volume of CEA. This paper assesses CEA and the effects of the introduction of CAS service on outcomes., Design: Retrospective cohort study., Methods: Clinical data and results of CEA were reviewed retrospectively for the treatment of carotid stenosis, between January 1988 and December 2010. CEA patients were grouped into those treated before and after the introduction of CAS to our hospital in 2001., Results: 757 patients underwent a CEA between 1988 and 2010. The perioperative stroke rate prior to the introduction of CAS was 4.9%, and 3.3% after stent introduction in 2001. In this latter period, 85.5% had symptomatic stenosis which suggests that the patients were not low risk. The major adverse event rate (inclusive of death and myocardial infarction) post introduction of CAS from 2001 to 2010 was 4.1%. There was no correlation between post-operative stroke/MAE and procedure volume, despite the trend of decreasing CEA numbers over time., Conclusion: The introduction of carotid artery stenting has led to a decrease in carotid endarterectomy volume. However, outcomes in our high risk patient population are acceptable. Therefore, CEA remains the procedure of choice for carotid artery revascularization., (Copyright © 2014 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Carotid endarterectomy (CEA) has been the standard of care for suitable patients with symptomatic or asymptomatic high grade carotid stenosis since the landmark NASCET (North American Symptomatic Carotid Endarterectomy Trial), ECST (European Carotid Surgery Trial) and ACAS (Asymptomatic Carotid Artery Surgery) studies performed in the 1990s and more recently the ACST (Asymptomatic Carotid Surgery Trial). Carotid artery stenting (CAS) in the treatment of both symptomatic and asymptomatic patients with high grade carotid stenosis has recently been investigated as an alternative to CEA. We present a review of the most recent CAS trials and examine some of the controversies that surround them.
