AbstractThe dogma for optimal arteriovenous fistula (AVF) creation is based on starting as distally as possible on the upper limb and progressing proximally. We herein present our findings of an AVF that is as distal as possible on the hand. To document primary patency rates of the distal-to-snuffbox AVF. A 10-year prospective study (2006–2016) involving 31 patients whose distal cephalic vein diameter was ≥3 mm with a normal Allen's test was conducted. Patients were excluded if the radial artery in the wrist was highly calcified, the cephalic vein did not dilate more than 3 mm with proximal compression, and there was previously failed AVF of the limb or previous trauma to the limb. The procedure was performed under local anesthetic, and the anastomosis performed with a 6.0 polypropylene suture in an end-to-side fashion. Thirty-one patients with end-stage renal disease underwent distal vascular access using the distal-to-snuffbox (Hitchhiker's) AVF (HAVF). During follow-up, eight patients died with an adequately functioning HAVF. The primary patency rates at 12, 24, 48, and 60 months were 90, 87, 85, and 82%, respectively. Failure occurred in six (19%) cases over the follow-up period, two in the first 2 weeks and four over a span of 60 months. Conclusion The creation of radiocephalic AVFs in the first web space, distal to the tendon of the extensor pollicis longus, serves as a viable option with acceptable success rates. This allows the surgeon more options with proper patient selection for this procedure.

Objective: Over two million individuals worldwide, with end-stage renal disease (ESRD), depend on dialysis therapy or a kidney transplant for survival. Every haemodialysis patient requires vascular access. The arteriovenous fistula (AVF) is preferred for long-term hemodialysis vascular access due to long-term primary patency rates. Given the limited options for haemodialysis access and placement, preservation of existing AVF sites is always a clinical priority. This case report describes a novel approach to wound closure with the application of dehydrated amnion chorion human membrane (dHACM) at an AVF surgical site known to be complicated with issues of scarring and tissue breakdown. The patient was treated successfully with the imperative preservation of his AVF given that he had few other vascular access options.

Abstract Background Arteriovenous fistulae (AVF) are the hemodialysis access modality of choice for patients with end-stage renal disease. However, they have a high early failure rate. Good vascular access is essential to manage long-term hemodialytic treatment, but some anesthesia techniques directly affect venous diameter as well as intra- and post- operative blood flow. The main purpose of this meta-analysis was to compare the results of regional and local anesthesia for arteriovenous fistula creation in end-stage renal disease.Methods: We conducted a systematic review and meta-analysis to synthesize evidence from 7 randomized controlled trials (565 patients) and 2 observational studies (524 patients) aim to evaluate the safety and efficacy of regional anesthesia (RA) versus local anesthesia (LA) in AVF surgical construction.Results: Pooled data showed that RA was associated with higher primary patency rates than LA (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.24 - 2.84; P = 0.003; I 2 = 31%; Figure 2a). Additionally, brachial artery diameter was significantly increased in the RA versus LA group (mean difference [MD] = 0.83; 95% CI: 0.75 - 0.92; P < 0.001; I 2 = 97%) and the need for intra- as well as post- operative pain killers was significantly less (RA, p = 0.0363; LA, p = 0.0318). Moreover, operation duration was significantly reduced in the RA (67.5 ± 8.9 min) versus LA (134.7 ± 14.8 min) group (p = 0.0007).Conclusions: In conclusion, compared with LA, RA shows higher primary patency rates and it also associated with significantly better intra- as well as post- operative pain control, reduced operative times, which are extremely important in patients with end-stage renal disease and severe comorbidities.

Venous Segment

Background To maintain the patency and longevity of arteriovenous fistula, the availability of a venous segment with adequate diameter is important. In Indian population, many chronic kidney disease patients have poor caliber veins. The study aimed to evaluate the efficacy of hydrostatic dilatation versus Primary balloon angioplasty of small caliber cephalic veins of (≤2.5 mm) preoperatively in terms of patency rate and maturation time of arteriovenous fistula. Methods Patients ( n = 80) with an end-stage renal disease requiring arteriovenous access surgery for hemodialysis with small caliber cephalic veins were randomized into two groups, i.e., hydrostatic dilatation and primary balloon angioplasty, each with 40 patients. All patients underwent a thorough clinical examination as well as duplex ultrasound vein mapping of both upper extremities. Patients were followed up for six months and primary patency, maturation time, and complications were noted. Results Immediate technical success with good palpable thrill was achieved in 97.5% of patients in the primary balloon angioplasty group and 87.5% in the hydrostatic dilatation group. The fistula maturation time in the primary balloon angioplasty group was 34.41 days and 46.18 days in the hydrostatic dilatation group. In the primary balloon angioplasty group, the primary patency of the fistula was 97.5% and 87.5% in the hydrostatic dilatation group, at six months. The arteriovenous fistula functioning rate was 77.5% in the hydrostatic dilatation group as compared to 92.5% in the primary balloon angioplasty group at six months. The incidence of surgical site infection was 5% in the primary balloon angioplasty group as compared to 10% in the hydrostatic dilatation group. Conclusion Primary balloon angioplasty of small caliber cephalic veins (≤2.5 mm) performed prior to arteriovenous fistula creation for hemodialysis is a beneficial procedure.

Objective This study aimed to evaluate the efficacy of beraprost sodium (BPS) or clopidogrel (CL) using vascular thromboembolic events (VTEs) of arteriovenous fistula as a primary endpoint in patients with end-stage renal disease (ESRD) undergoing arteriovenous fistula surgery. Methods We performed a multicentre, retrospective cohort study from August 2012 to August 2016. We studied patients with ESRD who underwent arteriovenous fistula surgery and received peroral administration of 40 µg BPS, three times per day, for 1 month, or 75 mg CL (initial dose of 300 mg), one time per day, for 1 month. The time to first on-study VTE was the primary endpoint. Results The BPS-treated cohort had a significantly delayed time to first VTE compared with the CL-treated cohort (hazard ratio 0.33, 95% confidence interval 0.18–0.56). An increased incidence of VTEs was detected in the 1-month follow-up, with rates of 2.4% and 8.7% for BPS and CL, respectively. This difference persisted over time, with rates of 8.0% and 18.1% at the final follow-up, respectively. Conclusion CL-treated patients with ESRD have a greater risk of VTEs compared with BPS-treated patients. CL-treated patients also tend to experience a VTE within the first month after cessation of oral administration.

Peritoneal dialysis (PD) interruption requiring hemodialysis (HD) is not uncommon and its frequently abrupt nature prevents timely creation of permanent HD access and avoidance of central venous catheters (CVC). We retrospectively studied a cohort of 24 end-stage renal disease (ESRD) patients (mean age 50.7 years, 83.3% African-Americans, 58.3% females, time on dialysis interquartile range [IQR] 0 - 65 days) who had simultaneous PD catheter insertion and backup arteriovenous fistula (AVF) creation between January 1, 2012, and December 31, 2013. The primary outcome of interest was the percent of patients receiving HD through the backup AVF at the time of PD interruption. A median (IQR) for PD catheter use after its insertion was 10.5 (2 - 20) days. After the mean follow-up of 19.6 months, 12 patients remained on PD, 2 patients received a kidney transplant, and 1 patient died. The overall AVF patency was 66.7%. A total of 9 (37.5%) patients had PD interruption requiring permanent (8 patients) or temporary (1 patient) HD after the mean (standard deviation [SD]) follow-up of 12.3 (8.2) months. Arteriovenous fistula was used as the initial access in 4 patients, and in 3 patients the original AVF was used after additional surgical revision. Forty-four percent of patients with a backup AVF fistula avoided CVC at the time of PD interruption requiring HD. The simultaneous AVF creation at the time of PD catheter insertion reduced but did not fully eliminate CVC at the time of PD interruption. Larger studies are needed to evaluate the utility of a backup AVF in PD patients.

Background: While COVID-19 in chronic hemodialysis patients has high mortality and the pandemic will not end in the near future, effective follow up strategies should be implemented for these patients. Surgeries have been triaged according to their level of urgencies and arteriovenous fistula (AVF) operations were among elective surgeries. This study aimed to analyze the effect of vascular access on the outcomes of hemodialysis patients who had COVID-19. Methods: One hundred four hemodialysis patients who had COVID-19 were retrospectively analyzed. Seventy-two of them had AVF as the vascular access while 32 of them had tunneled catheters. Inflammatory markers and outcomes of patients with AVFs and catheters were compared. A logistic regression analysis was performed in order to define factors that contribute to better outcomes in hemodialysis patients. Results: COVID-19 had high mortality rate in hemodialysis patients (36.5%). Patients with catheters have higher peak ferritin levels ( p = 0.02) and longer hospital stay ( p = 0.00). Having AVF as the vascular access (OR = 3.36; 95% CI: 1.05–10.72; p = 0.041) and using medium cut-off dialyzers (OR = 7.99; 95% CI: 1.53–41.65; p = 0.014) were related to higher survival of the patients. COVID severity was inversely proportional to the survival ( p = 0.000) Conclusions: AVFs contribute to higher survival of hemodialysis patients with COVID-19. Even in the pandemic era, end stage renal disease patients should be given the opportunity to have their vascular access properly created.

Work Up

Background: Chronic kidney disease (CKD) is a long term condition caused by damage to both kidneys. The benefits of arteriovenous fistulas over other forms of chronic access are: Arteriovenous fistulas are associated with decreased morbidity and mortality among hemodialysis patients compared with arteriovenous grafts and central venous catheters. Objectives of the study were o choose the proper sites for formation of arteriovenous fistula, to find out the success rate at various sites and to study the complications of arteriovenous fistula.Methods: This prospective study was carried out on total 150 patients over the duration of two years. The fistulae were created using radial artery and cephalic vein side to side (Radiocephalic AVF) and brachial artery and cephalic vein side to side anastomosis (Brachiocephalic AVF). Doppler studies were done before and after every procedure to demonstrate the velocity, volume of blood flow, depth from the skin, diameter of vessels and to access the time of maturation of AVF. Patients were followed up to first dialysis by AVF to assess the overall outcomes and various complications.Results: Brachiocephalic AVF matured earlier than Radiocephalic AVF (mean maturation time Brachiocephalic 38.02 days and Radiocephalic 43.26 days) which was statistically significant. Brachiocephalic AVF matured earlier than Radiocephalic AVF with more flow rate. Complication rate was more at wrist (Radiocephalic AVF with 66.67% of overall complication) than at elbow (Brachiocephalic AVF with 33.33% of overall complication).Conclusions: We concluded that the Brachiocephalic AVF maturation time was significantly less than the maturation time of Radiocephalic AVF and rate of complication was less in Brachiocephalic AVF. The utility of pre-operative colour Doppler to select the vessels for AVF creation was found to be as an essential parameter of pre-operative work up.

Background and aims: Arteriovenous fistula (AVF) maturation failure rates remain high in patients with end-stage renal disease (ESRD). Although preoperative morphological and functional assessment of blood vessels by duplex ultrasonography (DUS) has been shown to improve AVF maturation, there is no consensus regarding the optimal vein (VD) and artery (AD) diameters to be universally used for AVF creation. To improve patient selection, set out to investigate if there is a correlation between preoperative VD/AD and clinical covariates, and postoperative AVF outcome.Methods: This was a prospective cohort study conducted during January–August 2014. ESRD patients referred to “Niculae Stăncioiu” Heart Institute Cluj-Napoca, who had a VD ≥1.9 mm and AD ≥1.5 mm, as measured by DUS, and underwent AVF creation were enrolled. We assessed whether preoperative VD/AD and clinical covariates were associated with AVF maturation rate and primary patency at 2 years after AVF creation.Results: Of 115 patients referred for AVF creation, 93 were included in the study. Mean (± standard deviation) VD was 3.3 ± 1.1 mm and VDs were distributed in quartile Q1 <2.55 mm, Q2: 2.56-3.10 mm, Q3: 3.11-3.70 mm and Q4: >3.71 mm. Mean AD was 3.3 ± 1.4 mm and ADs were distributed in Q1 <2.55 mm, Q2: 2.56-3.10 mm, Q3: 3.11-3.70 mm, and Q4, >3.71 mm. AVF maturation rate increased proportionally with VD from Q1 (62%) to Q2 (70%), Q3 (82%) to Q4 (96%) (p=0.03). Based on AD, a higher AVF maturation rate was observed in Q3 (86%), Q4 (83%) vs Q1 (71%) and Q2 (67%). Long-term primary patency of AVFs seemed not to be influenced by VD and AD. In older patients and those with peripheral arterial disease, AVF maturation failure tended to be higher.Conclusions: Our findings suggest that a preoperative VD ≥1.9 mm and AD ≥1.5 mm have a successful maturation rate of AVF greater than 60% in ESRD patients. The maturation rate of surgical AVF increases proportionally with the size of VD used for AVF creation.

Central vein stenosis and thrombosis are frequent in patients on haemodialysis for end-stage renal disease. Its management includes anticoagulation, systemic or catheter-directed thrombolysis, mechanical thrombectomy and percutaneous transluminal angioplasty (PTA). Use of mechanical thrombectomy in central vein thrombosis has been scarcely reported. We hereby report a case of right brachiocephalic vein thrombosis with underlying stenosis, which was successfully treated by mechanical thrombectomy followed by PTA and stenting. The patient had a favourable 10 months of follow-up.
