Introduction: Arteriovenous fistula is considered as gold standard access for maintenance hemodialysis. Due to increasing burden of end-stage renal disease requiring dialysis, it is important for nephrologists to complement creation of arteriovenous fistula to meet the demand. Methods: This retrospective study was designed to assess the outcomes of arteriovenous fistula made by nephrologists at a tertiary care center from North India. The study included all radiocephalic arteriovenous fistula performed by nephrologists between November 2015 and January 2017. All arteriovenous fistulas were performed in patients whose duplex ultrasonography revealed both arterial and venous diameter of at least 2 mm. Data were collected with regard to age, gender, dialysis status, basic diseases, co-morbidities, and mineral bone disease parameters. The predictors of the primary and secondary patency rates were analyzed. Results: Five hundred patients (age 39.3 ± 14.4 years; 82.4% males; 21.6% diabetics) were included. In total, 83 (16.6%) patients had primary failure and 31 (7%) patients had secondary failure. Diabetes was associated with poor primary and secondary patency rates. Mean survival among the patients without primary failure was 11 months. The primary patency rates at 3, 6, 12, 18, and 21 months were 82%, 78%, 73%, 70%, and 70%, respectively. Conclusion: To conclude, the outcomes of radiocephalic arteriovenous fistulas created by nephrologists are at par with historic outcomes.

Purpose: Devices to permit percutaneous endovascular arteriovenous fistula formation have recently been introduced into clinical practice with promising initial evidence. As guidelines support a distal fistula first policy, the question of whether an endovascular arteriovenous fistula should be performed as an initial option is introduced. The aims of this study were to compare a matched cohort of endovascular arteriovenous fistula with surgical radiocephalic arteriovenous fistulas. Materials and methods: Using data from a prospectively collected database over a 3-year period, a matched comparative analysis was performed. Results: WavelinQ arteriovenous fistulas (group W, n = 30) were compared with radiocephalic arteriovenous fistulas (group RC; n = 40). Procedural success was high with 96.7% for group W and 92.6% for group RC. Primary patency at 6 and 12 months was greater in group W (65.5% 6mo and 56.5% 12mo) compared to group RC (53.4% 6mo and 44% 12mo) ( p = 0.69 and 0.63). Mean primary patency was significantly lower for RC (235 ± 210 days) vs W (362 ± 240 days) ( p < 0.05). Secondary patency for group W was 75.8% and 69.5% at 6 and 12 months, respectively. Secondary patency for RC was lower at 66.7% and 57.6% at 6 and 12 months, respectively. Conclusion: Outcomes of WavelinQ arteriovenous fistulas in this series are similar to published results. When compared to a contemporaneously created group of surgical fistulas, WavelinQ demonstrated superior outcomes. These data would support that WavelinQ endovascular arteriovenous fistulas may be considered as a first option in the access pathway particularly if vessels at the wrist are absent or less than ideal.

Arteriovenous Fistulas

Background: A substantial proportion of arteriovenous fistulas fail to function adequately for hemodialysis. Existing studies on arteriovenous fistula failure prediction assess patency rather than the more clinically relevant outcome of arteriovenous fistula function. We hypothesized that preoperative demographic and ultrasound characteristics, and postoperative assessment by an experienced vascular access nurse would predict which arteriovenous fistulas will not function adequately for hemodialysis. Methods: Prospective cohort study of chronic kidney disease patients at a tertiary care center in Vancouver, Canada, with arteriovenous fistula creation between 2009 and 2013. Pre and postoperative clinical assessment and ultrasound blood vessel mapping were performed by an experienced vascular access nurse. The primary outcome was failure to achieve a fistula used successfully for hemodialysis (FUSH). Results: Outcomes were assessed in 200 patients; 123 (61.5%) arteriovenous fistulas were radiocephalic. Overall, 26.5% of arteriovenous fistulas had FUSH failure (34.1% of lower arm vs 14.3% of upper arm, p = 0.002). Univariate predictors of FUSH failure included older age (p = 0.03), female sex (p = 0.05), smaller arterial diameter (p ⩽ 0.001), lower artery volume flow (p = 0.04), and smaller vein diameter (p = 0.01). In multivariable analysis, artery diameter (odds ratio: 0.44, 95% confidence interval: 0.28–0.68) most significantly predicted FUSH failure. Vascular access nurse assessment 6 weeks postoperatively correctly predicted outcome in 83.8% of FUSH and 65.0% of FUSH failure. Conclusion: Smaller artery diameter most strongly predicted FUSH failure. Early postoperative nursing assessment was more useful to predict FUSH than FUSH failure, and as such was insufficient in determining which arteriovenous fistulas should be abandoned as many predicted to fail could be salvaged with further intervention.

Introduction: The incidence of end-stage renal disease (ESRD) globally is 700 million people approximately. Patients with ESRD need vascular access for hemodialysis as renal replacement therapy (RRT). Among hemodialysis access, arteriovenous fistula is considered as the most preferred form of vascular access due to its characteristics. This study aimed to to present a descriptive characteristic of arteriovenous fistula creation cases in a tertiary care hospital with a specific view of demographic parameters, fistulas' sites, type of fistulas. Methods: We conducted a descriptive study of single-center in the Department of Thoracic, Cardiac and Vascular Surgery of Dr. Soetomo Academic General Hospital Surabaya, collected data from January 1st, 2017 to December 31st, 2020. All patients who undergo arteriovenous fistula creation considered as a subject in this study. We retrieved the characteristics of the patients, the type of fistula, the site, surgical technique, and underlying disease from patients’ electronic medical data records. Results: A total of 167 patients requiring long-term hemodialysis in our center. Females were dominantly in our study with 56.9% (95). Most of AVFs were created on the left arm. Radiocephalic type of AVF was the most common arteriovenous fistula type found in 111 subjects (66.5%). The highest postoperative successful rate was found in brachiocephalic type in 78.8%, followed by radiocephalic AVF type with 66.7%. The wrist region was favorable in subjects (43.1%). Conclusions: Arteriovenous fistulas for hemodialysis are needed and in our center. Radiocephalic AVFs are the most common type. Further study to learn the different aspects of arteriovenous fistula cases is needed to fulfill queries in the local population.

Introduction Anastomotic creation of autogenous arteriovenous fistulas can be performed in different ways, side-to-end or side-to-side. However, there is a paucity of evidence to recommend them. The aim of this study is to compare both anastomosis types in elbow arteriovenous fistulas. Material and methods A prospective observational national multicenter study (ISRCTN62033470) was designed, including patients receiving a native arteriovenous fistula in the elbow using side-to-end or side-to-side anastomosis, between September, 2016 and September, 2017, with six-month postoperative follow-up period. Patient characteristics, surgical details, and follow-up data (primary, assisted primary and secondary patency, maturation, functionality, complications) were recorded and compared between both anastomosis groups using Kaplan–Meier curves estimations, at one and six-month follow-up, and finally a multivariate analysis with Cox regression was performed. Results Three centers participated in the study, including 133 cases (96 side-to-end, 37 side-to-side). The cephalic vein was more often used for side-to-end (58.3%) and basilic for side-to-side (78.4%; P < 0.001). Side-to-end anastomoses were faster to create (65.1–75.1 min; P = 0.009). During follow-up, 23 cases were lost (transplanted, dead, ligated, or lost), with no differences at one month. At six months, primary patency was better for the side-to-end group (78.5 − 55.9%; P = 0.038), but it was not confirmed as an independent predictor in the multivariate analysis. Furthermore, no significant differences in assisted primary or secondary patency, maturation or functionality were seen. Patients with side-to-side anastomosis more often required vein superficialization (2.1–16.2%; P = 0.002) and presented more frequent puncture hematomas (4.9–30.0%; P = 0.015). Conclusions Anastomosis type was not significantly related to different outcomes in the follow-up. Even though side-to-end anastomosis showed better primary patency at six months with lower need of vein superficialization and fewer puncture hematomas during follow-up, it was not confirmed as an independent predictor in the multivariate analysis, and similar assisted primary and secondary patency, maturation, and functionality rates have been seen after arteriovenous fistula creation.

Delayed Maturation

Abstract Background and Aims Arteriovenous fistula is the optimal vascular access for hemodialysis as it has the best long-term patency rate and the lowest complication rate among hemodialysis vascular accesses. However, its occasional delayed maturation poses a challenge. Surgery has been advocated as the best treatment option. We proposed to evaluate the results of endovascular approach of arteriovenous fistula’s maturation delay in our hospital. Method We conducted a retrospective study, selecting patients referenced to our diagnostic and therapeutic angiography unit due to arteriovenous fistula delayed maturation, between April 2017 and October 2019. Physical examination and echography were used to confirm arteriovenous fistula delayed maturation. Results Thirty patients were referenced. Nine were excluded as maturation delay was not confirmed. Three patients were excluded due to extensive outflow stenosis since they were proposed to new vascular access creation. The other 18 patients were subjected to percutaneous endovascular treatment. Mean patient’s age was 65 years old. Twelve patients (66,7%) had forearm fistulas and the remaining (33,3%) had arm fistulas. Fourteen patients (77,7%) had maturation delay due to peri-anastomotic stenosis. The mean follow-up time was 14 months, (minimum - 3 months; maximum - 33 months). Seventeen fistulas (94,4%) were salvaged, although 3 (16,7%) needed a second intervention. Primary and secondary patencies at 3, 6 and 12 months were 77,8% vs. 94,4%, 69,2% vs. 92,3% and 75% vs. 100%, respectively. Arm fistulas had 83,3% of primary and secondary patencies. Forearm fistula’s primary and secondary patencies were 66,7% vs. 91,6%, 57,1% vs. 100% and 60% vs. 100%, at 3, 6 and 12 months, respectively. When maturation failure was due to peri-anastomotic stenosis, primary and secondary patencies were 71,4% vs. 92,9%, 66,7% vs. 100% and 66,7% vs. 100% at 3, 6 and 12 months, respectively. Conclusion Even though we are still lacking consensus about the best treatment option for fistula’s maturation delay, current guidelines suggest that, at least in delayed maturation due to peri-anastomotic stenosis, surgery may be the best treatment. Our results point out that endovascular treatment is a good treatment option for arteriovenous fistulas with maturation delay, mainly in the arm fistulas. Even though surgical treatment appears to have better primary patency, a step by step approach seems to be a valid approach, as our secondary patency shows.

Introduction: Tuberculosis (TB) is a one of the main causes of mortality and morbidity worldwide. Bactec MGIT (Mycobacteria Growth Indicator Tube) system is a rapid, reliable automated system for early diagnosis of pulmonary and extra pulmonary TB in setups where purchase of expensive instruments is not possible. The present study was thus carried out to evaluate AFB microscopy, culture on Lowenstein Jensen media and micro MGIT system for early and accurate diagnosis of Tuberculosis. Methods: A total of 280 samples were processed for direct AFB smear examination, and culture on micro MGIT and LJ media. The identification of Mycobacterium tuberculosis complex in positive cultures was done by MPT64 Ag card test (BD MGIT TBC Identification Test). Results: Out of the processed samples, (47.1%) 132/280 were positive for Mycobacterium spp by Micro MGIT, (35%) 98/280 on LJ medium and (25.7%) 72/280 by AFB smear. A total of (48.5%) 136 samples were positive by a combination of Micro MGIT and LJ medium. Among the total positive samples (136/280), Micro MGIT was found to be positive in 97% (132/136) of samples, LJ was positive in 72% (98/136), while 52.9% (72/136) were positive by AFB smear. Conclusion: Manual MGIT System is a simple and efficient, safe to use the diagnostic system. It does not require any expensive/special instrumentation other than the UV lamp for the detection of fluorescence. In areas with limited resources where the purchase of expensive instruments such as the MGIT 960 is out of scope, the use of manual MGIT for rapid susceptibility testing for MDR-TB could be an option. We would recommend testing MGIT 960 using first and secondline drugs to determine DST.

Purpose: To evaluate the usefulness and feasibility of using a reversible clinch knot with a guidewire in place rather than eliminating the access route during an arteriovenous hemodialysis access (AV access) intervention using the facing sheath technique. Material and methods: From July 2016 to June 2019, we retrospectively studied 78 sessions performed as interventional treatment for arteriovenous (AV) hemodialysis (HD) access using the “facing-sheath technique.” In all sessions, all antegrade sheaths were removed while a 0.035-inch guidewire remained in place with purse-string suture and the clinch knot. Seventy-two sessions were performed in patients with thrombosed AV accesses (69 arteriovenous grafts [AVGs] and three arteriovenous fistulas [AVFs]), and six sessions were carried out to treat non-thrombosed AV accesses (four AVGs and two AVFs). We evaluated whether proper hemostasis and successful reinsertion of the sheath over the wire into the clinch knot was achieved. Clinical success was defined as achieving prompt restoration of blood flow for AV access, and the postintervention primary and secondary patency were also evaluated. Result: In all 87 clinch knots created in 78 total sessions, proper hemostasis was achieved. All clinch knots that required reversal for additional procedures were successfully reopened (55 clinch knots in 50 sessions). The postintervention primary patency rates at 1, 3, and 6 months, and at 1 year were 77.8%, 68.9%, 55.6%, and 33.3%, respectively. The postintervention secondary patency rates at 1, 3, and 6 months, and also at 1 year were 93.3%, 91.1%, 86.7%, and 86.7%, respectively. Conclusion: Our AV access intervention which used a clinch knot with purse-string suture while the guidewire remained in place was both useful and feasible for maintaining temporary hemostasis.

AbstractVariceal bleeding is one of the most feared complications of cirrhosis and portal hypertension. Transjugular intrahepatic portosystemic shunt (TIPS) is an effective minimally invasive option to achieve adequate decompression of the portal system. The aim of the study was to assess the efficacy and complications of TIPS in patients presenting with variceal bleed. It was a retrospective study done in a tertiary care center in North India in cirrhotic patients with acute or recurrent variceal bleed who underwent TIPS from April 2010 to October 2013. All the patients were followed up till April 2014. We could successfully implant TIPS in 100% of our patients with 100% success rate in controlling variceal bleeding immediately and during the follow-up period. Our primary patency rate was 94.5% and overall patency rate was 100%. Major TIPS-related complication was hepatic encephalopathy in 20% of patients; 7 of 22 patients died during the follow-up period. TIPS is a safe and effective procedure for control of acute or recurrent variceal bleed. Emerging evidence in favor of early TIPS is further going to expand its indication in variceal bleed. Hepatic encephalopathy was the major procedure-related complication in our study consistent with previous literature reports.
