Abstract
BACKGROUND Arterio-venous fistulae are often compromised by complications, notably thrombosis. We assess the 2 year follow-up data of a cohort of patients from a single vascular centre in the UK who underwent BCF or RCF creation with the objective of assessing the outcome differences and intervention rates between fistula types. MATERIALS AND METHODS We retrospectively assessed a cohort of 195 patients who underwent creation of arterio-venous fistula (100 BCF, 95 RCF) between January 2016 and December 2018, following them up for 2 years assessing the outcomes and interventions on their AVFs. The outcomes assessed were primary and cumulative patency at 6 weeks, 6, 12 and 24 months. Multinomial logistic regression to account for confounding variables age, gender, procedure, side, anticoagulant, vessel size and co-morbidities was performed. A Kaplan-Meier analysis of time to endovascular intervention was also performed comparing RCF and BCF. RESULTS Cumulative patency rates for BCF vs RCF were 91% vs. 89% at 6 weeks (X2 (3, N = 194) = 4.70, P = .19), 83% vs. 76% at 6 months (X2 (3, N = 188) = 7.72, P = .05), 78% vs. 69% at 12 months (X2 (4, N = 175) = 5.37, P = .25) and 68% vs. 65% at 24 months (X2 (4, N = 161) = 5.24, P = .24). Endovascular intervention rate becomes divergent at 5 months, with the steepest difference between 6 and 12 months. Comparative endovascular intervention rates between BCF and RCF were 20% vs. 31% at 6 months, 41% vs. 40% at 12 months and 40% vs. 49% at 24 months. CONCLUSION RCF seem to have significantly lower patency at 6 months and have higher endovascular intervention rates compared to BCF. A focussed surveillance protocol could prove effective in improving outcomes for RCF.

Abstract
BACKGROUND The arteriovenous fistulas (AVF) continue to be the most prevalent type of vascular access for hemodialysis (HD). However, the appropriate locations of AVF are controversial. We conducted the meta-analysis to investigate the differences in patency between upper-arm and forearm AVF. METHODS PubMed, EMBASE, CENTRAL, and ISI Web of Science were searched to identify studies with differences in AVF patency at different locations. Reviewers searched the database, screened studies according to inclusion criteria, and conducted Meta-analysis. RESULTS A total of 12 studies involving 3437 patients were selected. Pooled data showed that primary patency (PP) of AVF were higher in upper-arm than forearm at 1 and 2 years (odds ratio [OR] = 1.54, p = 0.0005; OR = 2.45, p = 0.001), but the differences in cumulative patency (CP) were not statistically significant at 1 and 2 years (OR = 2.10, p = 0.08; OR = 2.16, p = 0.1). The differences in PP and CP between upper-arm and forearm AVF in patients older than 65 years were not statistically significant at 1 (OR = 1.61, p = 0.05; OR = 2.05, p = 0.17) and 2 years (OR = 3.40, p = 0.13; OR = 1.38, p = 0.16). In Asian patients, the differences in PP and CP between upper-arm and forearm AVF were not statistically significant at 1 (OR = 1.17, p = 0.41; OR = 1.02, p = 0.94) and 2 years (OR = 2.95, p = 0.08; OR = 1.23, p = 0.41). CONCLUSIONS In this study, the CP of upper-arm and forearm AVF was similar in overall population. There was no difference in PP and CP of AVF between upper-arm and forearm in Asian population or the elderly. The forearm AVF could be consider to be the first choice. for Asian patients or the elderly.

Abstract
PURPOSE Considering various factors, such as multiple co-morbidities, unsuitable vessels for access creation, non-maturation, vascular calcifications, the outcome of arteriovenous fistula (AVF) in the elderly population, may not be similar to the younger people. Our study aims to analyze the outcomes of AVF in elderly patients (> 65 year). METHODS It was a prospective observational study. Patients of more than 65 years of age in whom AVF was created from January 2012 to December 2015 were included in the study. These patients were followed up for 4 years. The primary endpoint of our study was to assess primary and secondary patency rates. RESULTS A total of 450 AVFs were included in the study. The mean age was 68.5 years. The most common site of AVF was radiocephalic (RCAVF) in 70% (n = 315), brachiocephalic (BCAVF) in 24% (n = 108) and basilic vein transposition (BVT) in 6% (n = 27). At 48 months, the primary patency rate of RCAVF, BCAVF, and BVT was 55%, 61.6%, and 60.4%, respectively. The commonest cause of access failure was thrombosis followed by non-maturation. CONCLUSION AVF remains the preferred vascular access for hemodialysis even in the elderly population. Failure to mature and thrombosis continue to be a concern with AVF. Location of the AV access does not seem to impact the long-term patency.

Abstract
OBJECTIVE To assess and compare the maturation rate of the native radiocephalic arteriovenous fistula (RC-AVF) created with and without a nitinol external support (VasQ™ Laminate Medical Technologies Ltd, Tel Aviv, Israel). METHODS Data of all consecutive patients who underwent the creation of native RC-AVFs at our center between October 2018 and January 2020 was prospectively collected and retrospectively analyzed.Selected patients who had a suitable vein and a radial artery with triphasic flow at preoperative duplex ultrasound exam and were selected for the creation of a radiocephalic fistula were included. Exclusion criteria were: malignant tumors, acute renal failure, previous upper limb revascularization, and septic status. Patency and maturation, vein, and artery diameter and blood flow rate were assessed at the following intervals: post-operatively, 24 h post-operatively, 1 month, 3 months, and 6 months post-operatively. RESULTS Forty-nine patients (31 males, mean age 65.7 years old) were included. Patients who received VasQ™ devices were 25 (VasQ group), the other 24 formed the control group. All patients underwent radio-cephalic AVF placement (21 on the wrist, 20 on the forearm, 8 on the proximal forearm). There were no perioperative complications and fatalities. At 1, 3, and 6 months, primary patency rates were 96 ± 4%, 96 ± 4%, 91 ± 6% (VasQ group) versus 87 ± 7%, 87 ± 7%, 80 ± 9% (control group, P 0.17), secondary patency rates were 96 ± 4%, 96 ± 4%, 91 ± 6% (VasQ group) versus 95 ± 4%, 90 ± 7%, 90 ± 7% (control group, P 0.79). A significantly larger vein diameter increase postoperatively (P 0.009) and a greater maturation rate (96% vs 74%, p 0.044) were found in the VasQ group compared to the control group. CONCLUSIONS The use of the VasQ™ device was associated with higher maturation rates and larger vein diameters postoperatively. The patency rates were slightly higher but not significantly. Further studies are needed to confirm these findings.

Abstract
항암치료를 위해 흉강 내 속목정맥의 천자를 통한 피하매몰 중심정맥 케모포트(implantable central venous chemoport) 도관의 설치 중 발생할 수 있는 의인성 속목정맥 천공은 매운 드문 합병증 중의 하나로 혈흉이나 출혈성 쇼크를 일으킬 수 있으며, 부적절한 항암제 주입으로 인한 늑막삼출이 발생할 수 있다. 따라서 항암제 주입 전 조기에 진단하여 응급 개흉술을 통해 천공된 속목정맥을 봉합하는 것이 치료 원칙이다. 저자들은 우측 속목정맥을 통한 피하매몰 중심정맥 케모포트의 설치 후 발생한 속목정맥 천공 환자에서 부적절한 항암제 주입으로 인해 발생한 늑막삼출과 혈흉을 개흉술을 시행하지 않고 경피적 배액술 후 코일과 N-butyl cyanoacrylate를 이용한 색전술을 통해 성공적으로 치료한 1예를 경험하였기에 이를 보고하고자 한다.
