Objective: To investigate the feasibility of percutaneous arteriovenous fistula creation in consecutive patients screened for first access creation. Methods: Prospective study of ultrasound mapping based on the following minimal anatomic requirements: a patent proximal radial artery and adjacent elbow perforating vein with straight trajectory, each greater than or equal to 2 mm in diameter and within 1.5 mm of each other. In addition, the same population was evaluated for feasibility of a distal radiocephalic fistula established. Results: One hundred consecutive patients were examined between November 2018 and January 2019. Sixty-seven were male (67%) and mean age was 61 years. Sixty-three patients (63%) and a total of 100 limbs (50%) were found to be eligible for a percutaneous fistula creation with Ellipsys®. Thirty-seven percent of patients were ineligible because of the absence of both median cephalic and median cubital veins (15%), absence or inadequate elbow perforating vein and/or smaller than 2 mm proximal radial artery (14%), and/or distance greater than 1.5 mm (8%). We found suitable vessels for a surgical distal fistula creation in 91 extremities (45%), but this percentage dropped to 17% in patients over 70 years old. Among the 100 limbs eligible for percutaneous arteriovenous fistula, only 30 (30%) were eligible for radiocephalic arteriovenous fistula. Conclusion: More than 60% of patients were eligible for Ellipsys. The absence of veins at the elbow and a large distance between vessels were the most common limiting factors. Less than one half of the patients were candidates for surgical fistula and this percentage dropped significantly for older individuals.

Abstract We present a case of dialysis associated steal syndrome in a hemodialysis patient with left radiocephalic arteriovenous fistula that caused him severe rest pain. Angiography showed retrograde flow from the ulnar artery to the distal radial artery through a hypertrophied palmar arch. The problem was solved by surgical ligation of the distal radial artery leading to complete relief of patient symptoms without any notable complications.

Background: The important effect of regular blood flow surveillance on arteriovenous fistula maintenance is emphasized. The ultrasonic dilution technique for blood flow surveillance can be performed during hemodialysis, but there are some limitations. Blood flow is traditionally measured by duplex Doppler ultrasound during the nondialysis period. However, the surveillance workload for arteriovenous fistula has increased with the rapid increase in the hemodialysis population size. Efficient methods for blood flow surveillance during hemodialysis are needed. Methods: Eighty-four hemodialysis patients with a forearm radiocephalic arteriovenous fistula were enrolled in this cross-sectional study. Each received blood flow measurements using ultrasonic dilution technique and duplex Doppler ultrasound during hemodialysis. Duplex Doppler ultrasound measurements included the blood flow of the brachial artery and radial artery. The correlations between these variables were analyzed. Results: The correlation coefficients ( r) between flow measured by ultrasonic dilution technique and brachial artery flow measured by duplex Doppler ultrasound, between flow measured by ultrasonic dilution technique and radial artery flow measured by duplex Doppler ultrasound, and between brachial artery flow and radial artery flow measured by duplex Doppler ultrasound were 0.724, 0.784, and 0.749, respectively (all p < 0.001). Conclusion: Blood flow measured by ultrasonic dilution technique was positively correlated with blood flow measured by duplex Doppler ultrasound during hemodialysis, suggesting that duplex Doppler ultrasound can be used to monitor the trends in the blood flow of the brachial artery and radial artery for timely intervention to improve patency during hemodialysis.

Objective: To investigate the hemodynamics of percutaneous arteriovenous fistulae (pAVF) created between the proximal radial artery and the deep communicating vein of the elbow. Methods: Consecutive patients with a percutaneously created proximal radial artery to perforating vein arteriovenous fistulae were evaluated and compared with control patients with clinically well-functioning surgical wrist radiocephalic arteriovenous fistulae (sWRC-AVF). Results: Thirty-one patients with a pAVF (21 males – 68%, mean age: 62 years, range: 53–81), with mean follow-up of 254 days (range: 60–443) and 32 patients with a surgical fistula (20 males – 62%, mean age of 63 years, range: 30–84) were evaluated. Mean access flow and distribution range were similar in the two study groups, with a mean flow of 859 mL/min vs 919 mL/min, respectively. There was no significant difference in the mean radial artery diameter (4 mm vs 4.3 mm, p = 0.2). Statistically significant trends were observed for resistive index (0.57 pAVF vs 0.52 (0.07) and brachial vein cross-sectional area (13 pAVF vs 33 mm2, p = 0.06). The arteriovenous anastomosis area was significantly smaller with pAVFs (13 vs 43 mm2, p = 0.002) and the pressure difference between extremities was less for the pAVF group vs sWRC-AVF (19 vs 27 mm Hg, respectively, p = 0.03). Existence of single cephalic or basilic versus cephalic and basilic outflow did not affect vein maturation or overall flow. Conclusions: pAVF have a favourable hemodynamic profile with many similarities when compared with surgically created wrist fistulae. Cephalic and/or basilic vein matured with only minor outflow shunted to the deep venous system.

Introduction: Hemodialysis is an essential treatment in patients with stage 5 chronic kidney disease (CKD) or End-Stage Renal Disease (ESRD). The maturity of arteriovenous fistulas determines the success of hemodialysis. FAV maturity depends on preoperative preparation. The study aims to examine the preoperative and intraoperative peak systolic velocity (PSV) of the radial artery as a predictor of the successful maturation of the radiocephalic FAV. Method: This study used an analytic cross-sectional design to obtain the relationship of FAV maturation with preoperative and intraoperative PSV. Subjects were those who will undergo radiocephalic FAV surgery with preoperative ultrasound mapping. Shortly after anastomosis, PSV was measured. After 6 weeks, FAV was assessed for its maturity. Results: As many as 71 patients were undergone radiocephalic FAV surgery and followed for six weeks. The mean preoperative PSV of mature fistula was significantly higher than immature (54.6 ± 11.7 cm/s and 26.7 ± 7.7 cm/s; p <0.001). The mean intraoperative PSV of mature fistula was significantly higher than immature (57.9 + 12.6 cm/s and 27.1 + 8.1 cm/s; p <0.001). The mean PSV difference in mature fistulas was significantly higher than immature (3 cm/s and 0 cm/s; p <0.001). Preoperative PSV with a cut-off of 40 cm/s, intraoperative with a cut-off of 42 cm/s, and a difference of PSV with a cut-off of 42 cm/s all had 92.9% accuracy as a predictor of FAV maturation compared to “rule of 6” as a reference standard. Conclusion: Preoperative PSV >40 cm/s and intraoperative PSV >42 cm/s had a good predictor value for radiocephalic FAV maturation.
