Renal arteriovenous shunts are direct communications between the supplying artery and draining vein without the presence of an intervening capillary bed. They can be traumatic or nontraumatic. Coils can be used for embolization of feeding arteries; however, they do not treat the nidus directly. Read More

Arteriovenous fistula (AVF) is a rare complication of the abdominal aortic aneurysm (AAA) with complex clinical features. However, AVF and AAA usually cause no symptoms except when they rupture. This case study demonstrated that ultrasonography was a rapid and non-invasive method for the initial assessment of AAA and AVF. Read More

We conducted a survey and semi-structured qualitative interviews to investigate current anaesthetic practice for arteriovenous fistula formation surgery in the UK. Responses were received from 39 out of 59 vascular centres where arteriovenous access surgery is performed, a response rate of 66%. Thirty-five centres reported routine use of brachial plexus blocks, but variation in anaesthetic skill-mix and practice were observed. Read More

Introduction: The central venous catheter (CVC) has been shown to increase mortality in hemodialysis (HD) patients compared with the arteriovenous fistula (AVF). However, no study has examined the mortality of HD patients based on the time of conversion from the CVC to AVF. In this study, we investigated the association between patients' survival and length of time of using each access. Read More

: An increase in the incidence of end-stage renal disease (ESRD) is associated with the need for a wider use of vascular access. Although arteriovenous (A-V) fistula is a preferred form of vascular access, for various reasons, permanent catheters are implanted in many patients. A retrospective analysis of clinical data was carried out in 398 patients (204 women) who in 2010-2016 were subjected to permanent dialysis catheters implantation as first vascular access or following A-V fistula dysfunction.

Background: Renal arteriovenous malformation (AVM) is a rare cause of massive hematuria, and patients with renal AVM may present with symptoms like urinary tract infections in the emergency department.

Case Report: A 37-year-old woman presented to the emergency department with symptoms of hematuria, urinary hesitancy, and severe suprapubic pain that had been present for a few hours.

Presented here is the case of a 21-year-old man, with a family history of unilateral renal agenesis, who presented with obstruction of his solitary functioning right kidney. Initially thought to be secondary to an obturator fossa hernia on endoscopic and retrograde pyelography assessment, diagnosis of obstruction secondary to an aberrant middle rectal artery was determined at laparotomy and division of this vessel relieved the patient's obstruction without any short-term or long-term complications. To the best of the authors' knowledge, this is the first reported case in the literature of hydroureteronephrosis secondary to an aberrant middle rectal artery. Read More

For patients with end-stage renal disease requiring hemodialysis, their vascular access is both their lifeline and their Achilles heel. Despite being recommended as primary vascular access, the arteriovenous fistula (AVF) shows sub-optimal results, with about 50% of patients needing a revision during the year following creation. After the AVF is created, the venous wall must adapt to new environment. Read More

One of the major causes of arteriovenous fistula failure is the venous stenosis due to aggressive neointimal hyperplasia. The aim of the study was to assess the arteriovenous fistula maturation comparing absorbable sutures and non-absorbable ones in native vessels. Surgeries performed during a period of 24 months by a single team of expert surgeons were evaluated. Read More

Introduction: The development of metastatic renal cell carcinoma (RCC) many years after a nephrectomy is not common but has been reported. A metastasis appearing as a hypervascular tumour, mimicking an arteriovenous malformation (AVM), is a highly unusual phenomenon, with a biopsy required for diagnostic confirmation. Surgery is an option for a solitary metastatic lesion amenable to complete excision, with proven survival benefits. Read More

Background: Arteriovenous dialysis access, fistulae (AVF) or grafts (AVG), are associated with significant rates of thrombosis. Timely thrombectomy may have a significant impact on immediate and long-term access survival.

Purpose: This study aimed to compare and contrast the American Society for Radiation Oncology (ASTRO) model policies (MPs) for intensity modulated radiation therapy (IMRT), stereotactic radiosurgery (SRS), stereotactic ablative radiation therapy (SABR), and proton beam therapy (PBT) with the coverage policies constructed by 5 of the largest publicly available commercial insurers throughout the United States (ie, Aetna, Anthem, Cigna, Humana, and United Healthcare).

Methods And Materials: Appropriate indications for IMRT, SRS, SABR, and PBT by disease site (and particular clinical setting thereof) were extracted from the most recently published ASTRO MPs and published coverage policies (2019 editions) of the 5 carriers. After tabulation, concordance between ASTRO MPs and insurance policies were calculated for each modality. Read More

The 6-O-endosulfatases (sulfs) are important enzymatic components involved in the regulation of heparan sulfate by altering the sulfatation pattern. Specifically in the kidney, sulfs have been implicated in the glomerular podocyte-endothelial cell crosstalk and in the preservation of the glomerular filtration barrier (GFB) in different mouse models. Since it has been shown that in zebrafish larvae, Sulf1, Sulf2a, and Sulf2b are expressed in the pronephric kidney we set out to establish if a reduction in sulf expression leads to GFB dysfunction.

We report a patient with a cirsoid renal arteriovenous malformation (AVM) causing massive hematuria that was successfully embolized by -butyl-2-cyanoacrylate under triple-balloon occlusion. Proximal balloons were placed in the renal artery and vein for flow control, and a coaxial microballoon was placed in a feeding artery of the AVM to control the delivery of -butyl-2-cyanoacrylate. Under triple-balloon occlusion, -butyl-2-cyanoacrylate embolization achieved complete occlusion of the AVM with no procedure-related complications, such as renal infarction. Read More
