And Function

In hemodialysis, vascular access is a key issue. The preferred access is an arteriovenous fistula on the non-dominant lower arm. If the natural vessels are insufficient for such access, the insertion of a synthetic vascular graft between artery and vein is an option to construct an arteriovenous shunt for punctures. In emergency situations and especially in elderly with narrow and atherosclerotic vessels, a cuffed double-lumen catheter is placed in a larger vein for chronic use. The latter option constitutes a greater risk for infections while arteriovenous fistula and arteriovenous shunt can fail due to stenosis, thrombosis, or infections. This review will recapitulate the vast and interdisciplinary scenario that characterizes hemodialysis vascular access creation and function, since adequate access management must be based on knowledge of the state of the art and on future perspectives. We also discuss recent developments to improve arteriovenous fistula creation and patency, the blood compatibility of arteriovenous shunt, needs to avoid infections, and potential development of tissue engineering applications in hemodialysis vascular access. The ultimate goal is to spread more knowledge in a critical area of medicine that is importantly affecting medical costs of renal replacement therapies and patients’ quality of life.

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.

The Impact

The need to have consistent methods and consistent technique to optimize hemodialysis outcomes is behind the concept of the Optiflow™ device. This device was created to allow for consistency in size of the arterial anastomosis and consistency in angle of the vein to the artery at the anastomosis. Early data suggest that allowing these two technical entities can improve outcomes in regards to flow and maturity in arteriovenous fistula creation. This article is a summary of early data that demonstrate the impact the Optiflow device on brachial cephalic fistulas.

Introduction A proximal ulnar artery arteriovenous fistula (PUA-AVF) is a logical vascular access option when the distal ulnar artery is occluded or inadequate in addition to other specific vascular anatomic variants. This study reviews a series of patients where the proximal ulnar artery was used for AVF inflow in establishing a reliable autogenous access for these uncommon patients. Materials and methods All new patients referred for vascular access with a PUA-AVF created during an eight-year period were evaluated. In addition to physical and ultrasound examinations, all patients had an Allen's test performed augmented with Doppler evaluation of the palmer arch. Analysis placed these patients into three anatomic groups: 1) A dominant radial artery with distal ulnar artery occlusive disease; 2) No cephalic or basilic vein option with an isolated and intact brachial vein originating from the ulnar vein for later staged transposition; 3) A proximal radial artery ≤2 mm in diameter and a normal Doppler augmented Allen's test. Results PUA-AVFs were created in 32 new patients during an eight-year period. Primary and cumulative patency rates were 80% and 94% at 12 months and 55% and 81% at 36 months. Follow-up was 2-62 months (mean 14 months). No patients developed steal syndrome during the study period. Conclusions A PUA-AVF is a safe and reliable autogenous access. It is particularly important when the radial artery is the only or dominant arterial supply to the hand, in patients with small but patent radial arteries, and in selected individuals requiring a brachial vein transposition.

We report a new technique called “reimplantation of an artery with a hairpin turn (RAHT)” to reduce excessive vascular access flow. A 73-year-old woman on dialysis consulted us for vascular surgery because of an increased cardiac preload. Chest radiography and echocardiography revealed an excessive shunt flow in the brachial artery (flow rate, 2336 mL/min). Vascular echo-Doppler of the left upper limb showed that the radial artery made a hairpin turn at the arteriovenous fistula (diameter, 9 mm). Diameters of the radial artery proximal and distal to the arteriovenous fistula were 5.4 and 3.7 mm, respectively. We ligated and divided the juxta-anastomosis proximal radial artery and subsequently created an end-to-side anastomosis between the proximal radial artery and the distal radial artery. The anastomosis ostium in the distal radial artery (the recipient) was formed with a 4-mm longitudinal and gently curved incision. We performed RAHT so that the small anastomosis between both arteries and the small diameter of the distal radial artery juxta-anastomosis segment could reduce the vascular access flow. The flow rates in the brachial artery were 500 mL/min just after surgery and 560 mL/min at 2 months after surgery. Postoperative chest radiography and echocardiography confirmed a decrease in cardiac preload. We believe that this RAHT technique could be useful as one of the options to reduce the flow in patients who have excessive vascular access flow with a radial artery that makes a hairpin turn.

Objective. To investigate the initial hemodialysis vascular access in Hangzhou and provide evidence for improving the use of autologous arteriovenous fistula by identifying factors associated with the choice of initial vascular access. Methods. We retrospectively studied the initial hemodialysis vascular access of 257 patients in five hemodialysis units in Hangzhou of China during a 21-month period (January 2018 to September 2019). A logistic regression was used to identify the risk factors of failing to use an arteriovenous fistula at the initiation of hemodialysis. Results. (1) 257 participants with mean age 67.65 ± 13.43 years old were reviewed, including 165 males (64.2%) and 92 females (35.8%). The etiologies of end-stage renal disease included diabetic nephropathy (37.35%), chronic glomerulonephritis (31.13%), hypertensive nephropathy (14.01%), and other diseases (17.51%). Only 51 patients (19.84%) received arteriovenous fistula, whereas the remaining 206 patients (80.16%) initiated dialysis with a central venous catheter. (2) Logistic regression analysis revealed that the independent risk factors for central venous catheter at the initial hemodialysis were age >70 years old ( OR = 4.827 , p < 0.01 versus ≤70 years old), chronic glomerulonephritis as the primary etiology ( OR = 2.565 , p < 0.05 versus nonchronic glomerulonephritis) and eGFR <8.5 mL/min/1.73m2 ( OR = 2.283 , p < 0.05 versus eGFR ≥8.5 mL/min/1.73m2). Conclusion. The proportion of patients using arteriovenous fistula as the initial hemodialysis vascular access in Hangzhou was still low. The choice of vascular access for the first hemodialysis was related to age, eGFR, and the primary etiology of end-stage renal disease. Increasing the proportion of planned vascular access and arteriovenous fistula at the initiation of hemodialysis is still our current goal.

Arteriovenous Fistula Stenosis

Background: Arteriovenous fistula (AVF) has better rate of patency and lower rate of complication compared to other vascular access for hemodialysis. One priority to be concerned is access failure for hemodialysis access is common findings and correspond with high healthcare cost, morbidity and mortality. Objective: This case report aimed to elaborate the proper management of patient with arterio fistula stenosis. Case Illustration: A man, 64 years old, stage V CKD with AVF in his left arm for hemodialysis access was admitted to our hospital due to difficulty in cannulation during his last hemodialysis. He had AVF For Hemodialysis access for two years. About 1 month before, he undergone surgery for creation of AVF for hemodialysis access in his right arm, but AVF was failed to reach maturation. Based on vascular doppler ultrasound (DUS) done in AVF of the left arm revealed there was stenosis in the juxta-anastomosis site and cephalic venous stenosis. Angioplasty was done in anastomose AVF and implantation of venous stent in the left cephalic vein. Conclusion: For patients on hemodialysis, vascular access is considered as the lifeline. Complications related to Vascular access is associated with morbidity and reduced quality of life. Surgery often difficult to do as readily as a percutaneous approach. In more than 80% of hemodialysis access underwent percutaneous interventions, flow was successfully restored. Based on this success rate, it has replaced surgical revision as the treatment of stenosis AVF.
