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 19905 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. [ABSTRACT FROM AUTHOR]

Background: The primary aim of this study was to assess the feasibility of introducing a digital health education tool (dHET) for varicose vein surgery., Methods: This randomized, feasibility study allocated 40 patients, into dHET (n = 20) or standard consent (SC) (n = 20) groups. Primary outcomes were related to feasibility. Secondary outcomes were knowledge recall, anxiety, and satisfaction., Results: Recruitment and retention rates were 100% and 97.5%, respectively. Acceptability was also rated high, confirming feasibility. There was also no evidence of a difference between groups for early knowledge recall (14 [12-17] vs. 14 [11-16]; P = 0.72) or delayed (at 2 weeks) knowledge recall (15 [13-16] vs. 15 [13-16]; P = 0.89). The dHET module took significantly longer to complete compared to SC (13 min [12-18] vs. 9 min [8-12]; P < 0.01). However, the control group asked significantly more questions about the intended procedure (P = 0.03). There was no evidence of a difference between groups for patient anxiety or satisfaction., Conclusions: This trial shows that the addition of a dHET is feasible and noninferior to SC. Digital consent provides a unique opportunity to promote patient education and autonomy for better shared decision making. It also offers better documentation of the consent process., (Copyright © 2024 The Author(s). Published by Elsevier Inc. All rights reserved.)

Background: There is an increasing need to increase simulation-based learning opportunities for vascular surgery residents in endovascular skills training. This study aims to explore the effectiveness of remote expert instructional feedback of endovascular simulation-based education, as a means of increasing training opportunities in this area for vascular surgery residents., Methods: A mixed-methods study design was adopted. Twelve vascular surgery residents from Ireland were tasked with completing two endovascular renal artery procedures: one with in-person expert feedback and the other with remote instruction. Participants ranged in experience levels from second year to final year of residency. Following the training activities, interviews and a questionnaire were employed to gather information on the usefulness of remote feedback., Results: There was no significant difference reported by participants using a post-event validated questionnaire between remote and in-person feedback. During the interviews, participants expressed mixed feelings about the presence of the educator while practicing, but they eventually saw no limiting factors to their practice when the trainer provided remote feedback. When receiving performance feedback remotely, clear communication and a shared knowledge of the task development are critical to success., Conclusions: We believe these findings can inform the design and development of remote learning and assessment of endovascular skills training and ultimately provide increased opportunities for more skills practice for vascular surgical residents., (© 2024.

Introduction: Doctors have a legal requirement and duty of care to ensure patients are enabled to make an informed decision about their treatment, including discussion of the benefits, risks and alternatives to a procedure. A patient-centred approach to consent has been firmly established in Ireland, and fundamental to this is the ability to engage in a dialogue that offers comprehensible information to patients. Telemedicine has revolutionised the way we can deliver care to patients in the modern era of computers, tablets, and smartphones, and its use has been rapidly expanded. Novel digital strategies to improve the informed consent process for surgical procedures have been increasingly under investigation over the last 10-15 years and may offer a low cost, accessible and tailored solution to consent for surgical interventions. Within vascular surgery, superficial venous interventions have been associated with a high number medicolegal claims and also represents an area within the specialty with rapidly evolving technology and techniques. The ability to communicate comprehensible information to patients has never been greater. Thus, the author's aim is to explore whether it is feasible and acceptable to deliver a digital health education intervention to patients undergoing endovenous thermal ablation (EVTA) to supplement the consent process., Methods: This is a prospective, single centre, randomised controlled, feasibility trial recruiting patients with chronic venous disease deemed suitable to undergo EVTA. Patients will be randomised to receive either standard consent (SC) or a newly developed digital health education tool (dHET). The primary outcome is feasibility; assessing the recruitment and retention rate of participants and assessing acceptability of the intervention. Secondary outcomes include knowledge retention, anxiety and satisfaction. This feasibility trial is designed to recruit 40 patients, which will allow for a moderate dropout rate. This pilot study will inform the authors of the appropriateness of an adequately powered multicentre trial., Discussion: To examine the role of a digital consent solution for EVTA. This may improve and standardise the consent dialogue with patients and may have the potential to reduce claims related to poor consent processes and disclosure of risks., Ethical Committee Reference: Ethical approval has been sought and received from both the Bon Secours Hospital and RCSI (202109017), on 14 May 2021 and 10 October 2021, respectively., Trial Registration: ClinicalTrials.gov Identifier: NCT05261412 , registered on 1 March 2022., (© 2023.

Objective: To reach consensus on a core set of essential information for inclusion in the informed consent process to standardize consent for VV surgery., Methods: Using a modified electronic Delphi (e-Delphi) method, a panel of experts in Ireland, were asked to rate statements of essential information to include in the informed consent process with patients. Statements were rated using a 5-point Likert scale. The definition of consensus was declared at 70% agreement by the panel., Results: Twenty-three panel members accepted the invitation to participate across three e-Delphi rounds. Consensus was reached on 33/42 statements, covering general and procedural information and the risks, benefits and alternatives of varicose veins (VV) surgery. Several statements remained equivocal, having not met consensus by the panel., Conclusion: Considerable consensus was reached within the panel of experts but some gaps in available research were also highlighted. This consensus may provide the framework to aid physicians to deliver a standardized discussion of the key elements of consent and shared decision making with patients.

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.
