Snuffbox Versus Wrist Radiocephalic Arteriovenous Fistulas: 10 Years Experience.

Background The wrist radiocephalic arteriovenous fistula (RCAVF) is the initial suggested procedure for establishing hemodialysis vascular access (HVA) in the most distal site of the upper limb. The anatomical snuffbox arteriovenous fistula (SBAVF) is barely utilised, despite its remote location. In this study, we aimed to analyse and compare the results of SBAVF and RCAVF in terms of their maturity, patency, and failure rates. Methodology This descriptive, retrospective study compared outcomes between SBAVF and RCAVF in terms of maturation, patency, and failure. All patients with chronic kidney disease who attended and underwent either procedure at Betsi Cadwaladr University Health Board between 2013 and 2023 were studied. Results In a period of 10 years, 179 patients were included. Overall, 102 (57%) were male and 77 (43%) were female, with a male-to-female ratio of 1.3:1. Wrist radiocephalic fistula was the dominant type of surgery done in 76% (n = 136), while the snuffbox radiocephalic fistula was done in fewer than 24% (n = 43) of patients. Most patients underwent a successful arteriovenous (AV) fistula (n = 105, 58.7%), in contrast to 67 patients whose fistulas failed. There was a significant relationship between fistula failure and complications (p = 0.000). There was no significant effect of the fistula site, hypertension, diabetes, cardiac diseases, smoking, peripheral vascular disease, or central vein stenosis on the failure of the AV fistula (p = 0.127, 0.534, 0.510, 0.397, 0.017, 0.68, and 0.371, respectively). Conclusions The snuffbox AV fistula is a suitable and feasible first choice for patients on hemodynamic therapy.

Early Experience With the Iliac Branch Endoprosthesis (IBE) in Managing Iliac Aneurysms.

Aim The objective of this study is to evaluate the feasibility of using iliac branch endoprosthesis (IBE) devices and to examine their short-term outcomes. Materials and methods This was a descriptive, retrospective observational study involving 15 patients diagnosed with either aortoiliac or isolated iliac artery aneurysms and treated with an IBE device. Data were collected for patients who received IBE devices at Glan Clwyd Hospital in Rhyl, United Kingdom, from February 2020 to May 2023. Results Most patients presented with asymptomatic aneurysms; 86.7% (n = 13) had bilateral common iliac artery (CIA) aneurysms. The mean diameter of the CIA was 38.7 ± 8.8 mm, and the mean diameter of the abdominal aortic aneurysm (AAA) was 39.8 ± 23 mm. For the indications of IBE use, 60% (n = 9) of the patients had iliac aneurysms reaching the intervention threshold, 20% (n = 3) had AAA reaching the threshold, and 20% (n = 3) had aortoiliac aneurysms reaching the threshold. The majority of patients underwent bilateral femoral access (86.7%; n = 13), while 13.3% (n = 2) required both femoral and brachial access. Technical success was achieved in all cases. Aside from 20% (n = 3) of cases where the sac size remained static, the majority of patients (80%; n = 12) experienced sac regression. All patients were free from buttock claudication. A type II endoleak was observed in 33.3% (n = 5) of patients. No reinterventions were reported. The mean primary patency was 30.9 ± 0.7 months, and the follow-up period ranged from 12 to 36 months. Conclusions IBEs are an effective medical device, demonstrating a high rate of technical success, minimal need for additional procedures, and a low incidence of complications while maintaining a satisfactory rate of primary patency.

Indications and Outcome of Carotid Endarterectomy (CEA): A Single Centre Experience.

Background Stroke is a prevalent ailment that impacts a substantial number of individuals globally, resulting in both physical impairment and mortality. One of its major causes is carotid artery stenosis. The symptoms and degree of stenosis are key indications for carotid endarterectomy (CEA). In this study, we highlight the indications and outcomes of carotid endarterectomy in our center. Methods This is a descriptive, retrospective, observational study. Data of patients who underwent CEA at Glan Clwyd Hospital from January 2018 to January 2023 was retrieved. The study sample consisted of patients diagnosed with symptomatic carotid artery stenosis who had CEA at Glan Clwyd Hospital. The data was analyzed using statistical software SPSS (IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp). Results A total of 150 patients were enrolled in the study. A majority of the patients were male, accounting for 69.3% (n = 104), and had a mean age of 71.1 ± 9.9 standard deviation. A majority of the patients were smokers (48.7%) and had additional medical conditions, including hypertension (34%), ischemic heart disease (17.3%), chronic obstructive pulmonary disease (73.3%), and diabetes (46.7%). Nevertheless, the remaining comorbidities were less common. The outcome of the CEA among the patients was cardiac event 3.3% (n = 5); transient ischemic attack (TIA) 3.3% (n = 5); stroke 0.6% (n = 1); hemorrhage 2.6% (n = 4); surgical site infection 2% (n = 3); perioperative mortality 1.3% (n = 2); and cranial nerve injury 1.3% (n = 2). However, no complications were reported in most of the patients, 85.6% (n = 128). Conclusion An endarterectomy is quite advantageous for treating symptomatic stenosis. The findings can be applied to patients who are physically suitable for surgery. The efficacy of endarterectomy is contingent upon not only the severity of carotid stenosis but also various other parameters, such as the time elapsed between the presenting event and the surgical intervention, as well as the patient's overall medical condition. However, the CEA is the gold standard in surgical management for symptomatic carotid disease.
