Ultrasound diagnostics of a spontaneous arteriovenous fistula of the head and neck

Journal of Ultrasonography, 2017
An arteriovenous fistula is an abnormal connection between the arterial and venous systems. In the literature, there are well-described ultrasound findings of iatrogenic arteriovenous fistula as a potential complication from percutaneous transarterial ...

Distress Analysis of Mice with Cervical Arteriovenous Fistulas

Animals, 2021
The welfare of laboratory animals is a consistent concern for researchers. Its evaluation not only fosters ethical responsibility and addresses legal requirements, but also provides a solid basis for a high quality of research.

Computational analysis for competition flows in arteriovenous fistulas based on non-contrast magnetic resonance imaging [PDF]

arXiv, 2023
Introduction: Characteristics of hemodynamics strongly affect the patency of arteriovenous fistula (AVF) in hemodialysis patients. Because of pressure balance changes among arteries after AVF construction, regurgitating flow occurs in some patients.

A systematic review and meta-analysis of systemic intraoperative anticoagulation during arteriovenous access formation for dialysis [PDF]

, 2015
Purpose: Surgical arteriovenous fistula (AVF) or graft (AVG) is preferred to a central venous catheter for dialysis access. Surgical access may suffer thrombosis early after placement and systemic anticoagulation during surgical access formation may ...

Staged brachioradial artery to brachioradial vein arteriovenous fistula creation for hemodialysis access in three patients with a high origin of the radial artery

Journal of Vascular Surgery Cases and Innovative Techniques, 2021
When patients lack suitable superficial veins in the upper extremity to create an arteriovenous fistula, surgeons are faced with a decision between a synthetic graft or autologous fistula using deep veins, such as a brachial artery to brachial vein ...

EFFECT OF HEPARIN ON THE PATENCY OF ARTERIOVENOUS FISTULA [PDF]

Acta Medica Iranica, 2008
"nPatients with end stage renal disease need a good vascular access for hemodialysis. Arteriovenous fistula is the method of choice for vascular access in these patients. However, failure of arteriovenous fistula due to thrombosis is a major problem.

Attention to pulmonary arteriovenous fistula in a case of transient hypoxemia and cerebral infarction during pregnancy: a case report and literature review

BMC Pregnancy and Childbirth, 2023
Background Pulmonary arteriovenous fistula is rare during pregnancy. Pulmonary arteriovenous fistula presents no pulmonary symptoms in most patients but can be exacerbated by pregnancy.

Deep denoising autoencoder-based non-invasive blood flow detection for arteriovenous fistula [PDF]

arXiv, 2023
Clinical guidelines underscore the importance of regularly monitoring and surveilling arteriovenous fistula (AVF) access in hemodialysis patients to promptly detect any dysfunction. Although phono-angiography/sound analysis overcomes the limitations of standardized AVF stenosis diagnosis tool, prior studies have depended on conventional feature ...

High-Flow Vascular Malformations in Children. [PDF]

, 2020
Children can have a variety of intracranial vascular anomalies ranging from small and incidental with no clinical consequences to complex lesions that can cause substantial neurologic deficits, heart failure, or profoundly affect development. In contrast

Outcome of Kidney Allografts in Recipients With a Femoral Arteriovenous Fistula: Report of Two Cases

Urology Case Reports, 2016
Two patients, who were on hemodialysis over a femoral arteriovenous fistula, were transplanted in our center. Despite adequate blood pressure, perfusion of the renal allograft remained poor after completion of the vascular anastomoses.
