Underlying Pathology

Impaired fistula maturation is associated with puncture-related complications, insufficient dialysis and potential permanent access failure. Non-maturation is frequently initiated by stenotic vascular access vessels comprising the outflow veins, the arteriovenous anastomosis and infrequently the inflow artery. Further findings in maturation protraction are central venous stenoses or accessory outflow veins. Depending on the underlying pathology, several endovascular approaches to boost fistula maturation are possible. To date standard balloon angioplasty remains the primary proven treatment option.

Fistula Maturation

The goal of vascular access creation is to achieve a functioning arteriovenous fistula (AVF) or arteriovenous graft (AVG). An autologous fistula has been shown to be superior to AVG or to central venous catheters (CVCs) with lowest rate of re-intervention, but vessel obstruction or immaturity accounts for 20 % to 54% of cases with primary failure of AVF. This review is focused on the factors influencing maturation; indication and timing of preoperative mapping/creation of vascular access; ultrasound parameters for creation AVF/AVG; early postoperative complications following creation of a vascular access; ultrasound determinants of fistula maturation and endovascular intervention in vascular access with maturation failure. However, vascular accesses that fail to develop, have a high incidence of correctable abnormalities, and these need to be promptly recognized by ultrasonography and managed effectively if a high success rate is to be expected. We review approaches to promoting fistula maturation and duplex ultrasonography (DUS) of evaluating vascular access 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.

The Individual

In February 2008 a multidisciplinary study group was established in Germany to improve the treatment of patients with potential vascular access problems. As one of the first results of their work interdisciplinary recommendations for the management of vascular access were provided, from the creation of the initial access to the treatment of complications. As a rule the wrist arteriovenous fistula (AVF) is the access of choice due to its lower complication rate when compared to other types of access. The AVF should be created 3 months prior to the expected start of haemodialysis to allow for sufficient maturation. Second and third choice accesses are arteriovenous grafts (AVG) and central venous catheters (CVC). Ultrasound is a reliable tool for vessel selection before access creation, and also for the diagnosis of complications in AVF and grafts. Access stenosis and thrombosis can be treated surgically and interventionally. The comparison of both methods reveals advantages and disadvantages for each. The therapeutic decision should be based on the individual patients’ constitution, and also on the availability and experience of the involved specialists.

Background: Pandemics create challenges for medical centers, which call for innovative adaptations to care for patients during the unusually high census, to distribute stress and work hours among providers, to reduce the likelihood of transmission to health care workers, and to maximize resource utilization. Methods: We describe a multidisciplinary vascular access team’s development to improve frontline providers’ workflow by placing central venous and arterial catheters. Herein we describe the development, organization, and processes resulting in the rapid formation and deployment of this team, reporting on notable clinical issues encountered, which might serve as a basis for future quality improvement and investigation. We describe a retrospective, single-center descriptive study in a large, quaternary academic medical center in a major city. The COVID-19 vascular access team included physicians with specialized experience in placing invasive catheters and whose usual clinical schedule had been lessened through deferment of elective cases. The target population included patients with confirmed or suspected COVID-19 in the medical ICU (MICU) needing invasive catheter placement. The line team placed all invasive catheters on patients in the MICU with suspected or confirmed COVID-19. Results and conclusions: Primary data collected were the number and type of catheters placed, time of team member exposure to potentially infected patients, and any complications over the first three weeks. Secondary outcomes pertained to workflow enhancement and quality improvement. 145 invasive catheters were placed on 67 patients. Of these 67 patients, 90% received arterial catheters, 64% central venous catheters, and 25% hemodialysis catheters. None of the central venous catheterizations or hemodialysis catheters were associated with early complications. Arterial line malfunction due to thrombosis was the most frequent complication. Division of labor through specialized expert procedural teams is feasible during a pandemic and offloads frontline providers while potentially conferring safety benefits.

Intracerebral hemorrhage is a devastating form of stroke and is more common in patients with hypertension and renal disease. We present the case of a lady suffering from chronic kidney disease who presented with severe headache and aphasia. On evaluation, she was found to have an intraparenchymal hemorrhage in the left temporal lobe with prominent pial and dural veins suggestive of a dural arteriovenous fistula (DAVF). Subsequently, she was detected to have occlusion of the left brachiocephalic vein (LBCV), which resulted in venous hypertension and resulted in this rare complication. Angioplasty followed by stenting of the LBCV resulted in subsidence of her symptoms. We wish to highlight this unusual but treatable complication of limb AV fistula which can mimic intracranial DAVF.

Native Fistula

The long-term survival and quality of life of patients on hemodialysis is dependant on the adequacy of dialysis via an appropriately placed vascular access. The native arteriovenous fistula (AV fistula) at the wrist is generally accepted as the vascular access of choice in hemodialysis patients due to its low complication and high patency rates. It has been shown beyond doubt that an optimally functioning AV fistula is a good prognostic factor of patient morbidity and mortality in the dialysis phase. Recent clinical practice guidelines recommend the creation of a vascular access (native fistula or synthetic graft) before the start of chronic hemodialysis therapy to prevent the need for complication-prone dialysis catheters. A multidisciplinary approach, including nephrologists, surgeons, interventional radiologists, and nurses should improve the hemodialysis outcome by promoting the use of native AV fistulae. An important additional component of this program is the Doppler ultrasound for preoperative vascular mapping. This approach may be realized without unsuccessful surgical explorations, with a minimal early failure rate, and a high maturation, even in risk groups such as elderly and diabetic patients. Vascular access care is responsible for a significant proportion of health care costs in the first year of hemodialysis. These results also support clinical practice guidelines that recommend the preferential placement of a native fistula.
