Abstract
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.

Snuff-Box Versus Wrist Radiocephalic Arteriovenous Fistulas for Hemodialysis: Maturation Tend and its Affecting Factors. Ann Vasc Surg 2022; 87:495-501. [PMID: 35780948 DOI: 10.1016/j.avsg.2022.05.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 05/11/2022] [Accepted: 05/18/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Thanks to its well proved long-term patency rates, native radiocephalic arteriovenous fistula remains the most commonly used vascular access type. Many articles had approached the criteria leading to a mature fistula. The aims of this work are to evaluate variables that may affect the maturation of distal fistulas and to determine if wrist fistulas have less risk of maturation failure than the snuff-box fistulas. METHODS We recorded all distal radiocephalic fistulas that had been created from January 2018 to February 2021. Epidemiological and clinical profile of patients, characteristics of performed fistulas and per and post-operative data were recorded and analyzed. RESULTS From January 2018 to February 2021, 165 upper limb vascular accesses for hemodialysis had been created including 47 (28.5%) distal radiocephalic fistulas. Among the latter, 39 (83%) fistulas were performed at the wrist and 8 (17%) at snuff-box area. There were 34 men (72.3%). Mean age was 67 years (37-87). Both types of fistulas had approximately an identic frequency of primary maturation failure (50% for radiocephalic versus 47.2% for snuff-box fistulas). Secondary maturation had been achieved in 9 fistulas. Patients with medical history of dyslipidemia, peripheral arterial disease (PAD), central catheter placement, and bad quality of vessels tend to develop an immature fistula. CONCLUSIONS No significant differences in maturation tend between snuff-box and wrist fistulas had been demonstrated. Thus, it seems reasonable to privilege the creation of the most distal fistulas allowing preservation of wrist fistulas as a second option in case of snuff-box fistulas maturation failure. However, selection of the most suitable cases for snuff-box fistulas creation, based on clinical and duplex ultrasound data, remains primordial.

Abstract
OBJECTIVE Autologous arteriovenous fistulas in the arm have been shown to be superior to all other types of arteriovenous access and should be placed as far distally as possible. The aim of the present study was to delineate the advantages of snuffbox fistulas (SBFs). METHODS From January 2007 through April 2017, first time or new arteriovenous fistula surgery was performed in 375 patients. If feasible, an SBF was chosen. The observation period ended in December 2019. The focus of the present study was on the patency rates, redo surgery, complications, and mortality rates. RESULTS SBFs were created in 236 patients (92 women and 144 men; mean age, 67 years; 46% with diabetes). Within the first 6 weeks, 11% of the fistulas had failed. The primary patency rates were 75%, 69%, 64%, 61%, 60%, and 58% after 1, 2, 3, 5, 7, and 9 years, respectively. The secondary patency rates were 86%, 83%, 80%, and 77% after 1, 2, 3, and 5 years, respectively. Age, sex, and the presence of diabetes mellitus had no effect on the primary patency rates. Patients with a right-sided SBF had significantly worse primary patency. Of the 236 patients, 154 (65%) had died during the observation period. The incidence of surgical site infection within the first 30 days and access-related ischemia during the observation period was <1%. CONCLUSIONS The results from the present study have shown that with suitable anatomic conditions, a SBF is a good choice for the creation of dialysis access. The patency rates were encouraging, and it offers the longest puncturable segment of the cephalic vein. Also, the rate of perioperative complications was low.

Abstract
Background Arteriovenous fistulae (AVFs) may remain patent after kidney transplantation (KTx), contributing to maladaptive cardiac remodeling. The flow in AVFs is associated with the diameter of its vessels and thus with the AVF location. The main objective of this study is to assess the influence of AVF location and its patency on the self-reported quality of life (QOL) of kidney transplant recipients (KTRs) with past history of hemodialysis. Methods To gain clinical data, during a scheduled visit, 353 KTRs were asked to fill out an anonymous questionnaire. From this group, 284 respondents were found eligible for analysis. The outcome was defined as prevalence of symptoms and health status, measured with the Left Ventricular Dysfunction-36 (LVD-36) Questionnaire in symptomatic patients. Results The hemodialysis patients (n = 243) were divided into two groups according to AVF location, i.e., DAVF – distally located AVF – (n = 174) and PAVF – proximally located AVF – (n = 69). The proportion of patients with heart failure (HF) was higher in PAVF group (24% vs. 12%, p = 0.0482). In the multivariable regression, PAVF, serum creatinine levels, and the presence of HF or coronary artery disease (CAD) remained independent predictors of lower functional capacity. Among patients with heart disease, the presence of active AVF was independently associated with worse functional outcome (higher LVD-36 scores). Conclusions The influence of persistent PAVF in KTRs seems to be unfavorable, especially when coexisting with CAD or HF.

Abstract
OBJECTIVE The Society for Vascular Surgery guidelines for permanent hemodialysis (HD) access creation recommend prioritizing the most distal possible autogenous access to minimize complications and preserve more proximal options. The "snuffbox" arteriovenous fistula (AVF) is the most distal radial artery-cephalic vein AVF. Despite the theoretical benefits of the snuffbox approach, recent trends have been toward upper arm access. Our study sought to investigate the feasibility of a snuffbox-first strategy for HD access in all anatomically appropriate candidates. METHODS From January 2016 to August 2019, all patients with end-stage renal disease (ESRD) or pre-ESRD under consideration for HD access were evaluated for a snuffbox-first approach by a team of vascular surgeons and nephrologists at a single, urban academic medical center in the United States. Data were collected prospectively and supplemented by medical record review. A survival analysis was performed to evaluate primary unassisted and secondary patency and clinical and functional maturation. Patients were censored if they had received a kidney transplant or had died. Cox proportional hazards regression was used to determine the risk factors for prolonged clinical maturation and functional maturation. RESULTS A total of 55 snuffbox AVFs were created. The median patient age was 60 years (interquartile range [IQR], 52-70 years), and 52.7% of the patients were men. The median follow-up was 369 days (IQR, 166-509 days). The median survival for primary unassisted patency was 90 days (95% confidence interval [CI], 79-111). Secondary patency at 1 year was 92.3% (95% CI, 85.3%-99.9%). The clinical maturation rate at 1 year was 83.7% (n = 55; 95% CI, 66.8%-91.9%), and the functional maturation rate at 1 year was 85.6% (n = 40; 95% CI, 63.3%-94.4%). Of the patients who were pre-ESRD at AVF creation and had initiated HD during the study period, 87.5% had successfully received incident HD with their snuffbox AVF. Twenty-four patients were receiving HD via a catheter at snuffbox creation. Of those patients, the functional maturation rate at 1 year was 82.5% (95% CI, 44.8%-94.4%). The patients had undergone a median of two interventions (IQR, zero to seven interventions) in the first year. Of these, 46.9% were percutaneous angioplasty and 31.2% were side-branch ligation. Diabetes was associated with slower AVF clinical maturation (multivariate hazard ratio, 0.35; 95% CI, 0.15-0.82; P = .016). A larger artery diameter was associated with earlier AVF clinical maturation (multivariate hazard ratio, 6.64; 95% CI, 2.11-20.9). CONCLUSIONS A snuffbox-first approach to HD access is a viable option for distal access creation in a cohort of patients requiring HD in the United States. Subsequent ancillary interventions to facilitate access maturation were required for most patients.

Abstract
BACKGROUND The VasQTM device was designed to improve the outcome of arteriovenous fistulae by optimizing the hemodynamics of the flow in the juxta-anastomotic region of the arteriovenous fistulae through tailored external support. The aim of the study was to evaluate the impact of the VasQ on outcome of radiocephalic arteriovenous fistulae in a real-world setting. METHODS This was a single-center, retrospective analysis of patients with either fistula creation before or after dialysis initiation with implantation of the VasQ device during creation of end-to-side radiocephalic arteriovenous fistulae between June 2018 and May 2019. The flow rate and vein diameter were evaluated intraoperatively, at discharge within 48 h postprocedure and at a follow-up of 1, 3, 6, 9, and 12 months. RESULTS Thirty-three VasQ devices were implanted during 33 radiocephalic arteriovenous fistula procedures. The study population comprised mostly of men, with an average age of 66 years. Mean intraoperative flow was 428 mL/min (range: 130-945). All patients were discharged with patent arteriovenous fistulae and mean fistula flow of 740 mL/min (range: 230-1300 mL/min). The primary patency was 100% and 79% at 3 and 6 months, respectively. Cumulative/secondary patency was 100% and 90% at 3 and 6 months, respectively. CONCLUSION Data presented here suggest that the VasQ device has the potential to provide benefit to the functionality of radiocephalic arteriovenous fistulae.
