Superior mesenteric arteriovenous fistula embolization with a vascular plug for upper gastrointestinal hemorrhage: a case report

CVIR Endovascular, 2022
Background Superior mesenteric arteriovenous fistula is a rare vascular anomaly often presenting with sequelae of portal hypertension, heart failure, or mesenteric ischemia.

A case of subarachnoid hemorrhage due to perimedullary arteriovenous fistula with multiple feeders at the craniocervical junction cured by treating the common draining vein and a review of the literature

Brain Hemorrhages, 2023
Objective: Craniocervical junction arteriovenous fistula (CCJ-AVF) is a rare disease, and preoperative imaging evaluation is important in developing treatment strategies due to the complexity of the vascular architecture, such as the feeding vessels ...

Medial tentorial dural arteriovenous fistula: A rare cause of bithalamic oedema

Radiology Case Reports, 2022
A 39-year-old man was admitted after 1 week of headaches and cognitive changes. CT scan showed bithalamic hypodensities, corresponding to bithalamic vasogenic oedema. Punctuate hemorrhage was present, with foci of thalamic enhancement.

Arteriovenous access in hemodialysis : A multidisciplinary perspective for future solutions [PDF]

, 2020
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 ...

Occurrence of Metachronous Intracranial Dural Arteriovenous Fistula after Embolization of Intracranial Dural Arteriovenous Fistula: A Case Report

Journal of the Korean Society of Radiology, 2023
Intracranial dural arteriovenous fistula (DAVF) is an abnormal arteriovenous shunt accounting for approximately 10%–15% of all intracranial vascular malformations. Most intracranial DAVFs are solitary, but multiple lesions at different sites can rarely

Effect of initial gas bubble composition on detection of inducible intrapulmonary arteriovenous shunt during exercise in normoxia, hypoxia, or hyperoxia

, 2011
Concern has been raised that altering the fraction of inspired O2 (FiO2) could accelerate or decelerate microbubble dissolution time within the pulmonary vasculature and thereby invalidate the ability of saline contrast echocardiography to detect ...

Simultaneous findings of shunt obliteration and arterial flow restoration during balloon-assisted technique in the management of idiopathic vertebral arteriovenous fistula

Radiology Case Reports
The etiology of vertebral arteriovenous fistulas (VAVFs) is diverse, and when selecting an optimal therapeutic strategy, it is important to evaluate the feasibility of preserving the vertebral artery (VA).

Renal arteriovenous oxygen shunting [PDF]

Current Opinion in Nephrology and Hypertension, 2017
Renal arteriovenous oxygen shunting has been proposed as a mechanism by which oxygen supplied to the kidney can bypass the renal parenchyma. Shunting could, therefore, play a crucial role in renal hypoxia and hyperoxia. In the absence of suitable quantitative experimental methods, computational modeling has been employed in recent years to estimate the

Local hemodynamics and intimal hyperplasia at the venous side of a porcine arteriovenous shunt

, 2010
Venous anastomotic intimal hyperplasia (IH) observed in the arteriovenous shunt (AVS) has been associated with disturbed hemodynamics. This study aims to correlate hemodynamics with wall histology and wall mechanics by examining the flow field in AVS ...

Time course of flow-induced adaptation of carotid artery biomechanical properties, structure and zero-stress state in the arteriovenous shunt

, 2012
Numerous studies have provided evidence of diameter adaptation secondary to flow-overload. but with ambiguous findings vis a vis other morphological parameters and information on the biomechanical aspects of arterial adaptation is rather incomplete.
