Two devices for the creation of an endovascular percutaneous (pAVF) endovascular (endoAVF) arteriovenous fistulae (AVF) are available: the Ellipsys and the WavelinQ-4F systems. The main difference is the location of the anastomosis, making it feasible to use both pAVFs and surgical Gracz-type AVF in an algorithm sequence. A 66-year-old male patient with end-stage kidney disease and HIV was referred for a creation of a dialysis access after failed peritoneal dialysis. A radial-radial WavelinQ-pAVF with simultaneous coil embolization of a brachial vein was created but failed within 4 weeks. Therefore, an Ellipsys-pAVF was successfully created between the proximal radial artery and perforating vein on the same arm. After 2 days, however, the Ellipsys-pAVF anastomosis occluded. The ipsilateral Gracz-AVF was created, anastomosing perforating vein with the antecubital brachial artery. Cannulations were started 28 days later. During the follow up of 807 days, the AVF remained patent with last known volume flow of 1500 ml/min and no need for secondary interventions. We report a successful creation of a Gracz-AVF after primary failed pAVFs created with both pAVF-systems in a single patient and in the same arm. Thus, based on that case we recommend creation of pAVF prior to Gracz-AVF as integral part of Vascular Access creation algorithm, based on each patient's life plan.

Background: Dural arteriovenous fistulas (DAVFs) are abnormal communications between dural arteries and cortical, meningeal, or dural sinus veins. They represent 10-15% of intracranial arteriovenous malformations. In rare cases, they have been associated with potentially reversible cognitive impairment and dementia.

Introduction: The 2019 Kidney Disease Outcome Quality Initiative guidelines emphasize the importance of selecting dialysis based on the life expectancy of the patient. However, it is difficult to predict the life expectancy of a patient during arteriovenous fistula creation. We investigated whether neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios measured before dialysis could predict mortality.

Hemodialysis for chronic kidney disease (CKD) relies on vascular access (VA) devices, such as arteriovenous fistulas (AVF), grafts (AVG), or catheters, to maintain blood flow. Nonetheless, unpredictable progressive vascular stenosis due to neointimal formation or complete occlusion from acute thrombosis remains the primary cause of mature VA failure. Despite emergent surgical intervention efforts, the lack of a reliable early detection tool significantly reduces patient outcomes and survival rates.

Autogenous arteriovenous fistula (AVF) is the vascular access of choice for chronic kidney disease to patients requiring hemodialysis. However, there still needs to be more consensus on whether the best surgical approach is an end-of-vein to side-of-artery (ETS) or a side-of-vein to side-of-artery (STS) anastomosis. This study aims to compare venous maturation rates, mid-term patency and post-operative steal syndrome rates between ETS and STS techniques for arteriovenous fistulas.

Purpose: A persistent trigeminal artery is the most common persistent carotid-vertebrobasilar anastomosis. Persistent trigeminal artery variants (PTAVs) terminate in the cerebellar arteries without connecting to the basilar artery; of these, the anterior inferior cerebellar artery (AICA) is the most common. AICA duplication is frequently observed.
