Pulmonary Arteriovenous Malformation can be Associated with Embolic Stroke of Undetermined Source (ESUS)

European Journal of Case Reports in Internal Medicine, 2019
Pulmonary arteriovenous malformations (PAVMs) are rare vascular anomalies. Alternative designations are pulmonary arteriovenous fistulae or aneurysms. Although mostly asymptomatic, PAVMs can cause respiratory symptoms due to right-to-left shunt.

The usefulness of electrophysiological monitoring during resection of central nervous system vascular malformations

Journal of Stroke and Cerebrovascular Diseases, 1999
The purpose of this study was to evaluate the usefulness of electrophysiological monitoring during the resection of vascular malformations.Between September 1994 and April 1996, we surgically resected vascular malformations (31 arteriovenous malformations, 22 angiographically occult vascular malformations) from 53 patients (56 procedures) and used ...

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

Advanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

A case report of pulsatile tinnitus as a symptom of brain arteriovenous malformation

The Journal of Qazvin University of Medical Sciences, 2015
Pulsatile tinnitus is the result of blood flow related sounds transmitted to the inner ear and coincides with heartbeat. Although pulsatile tinnitus is a rare entity, this symptom is most often indicative of a serious underlying disease in central ...

Stable Protein‐Based G‐Quadruplex‐Derived Supramolecular Bioinks as Tunable ECM‐Mimetic Constructs Assembled by Combining Non‐Covalent and Covalent Strategies

Advanced Materials, EarlyView.
Harnessing the synergistic interplay of supramolecular self‐assembly, under macromolecular crowding conditions, and enzymatic‐mediated covalent crosslinking toward a stable protein‐based G‐quadruplex‐derived supramolecular bioink. This bioinspired strategy enables the biofabrication of complex and tunable ECM‐mimetic constructs, providing a platform ...

Transulnar Arterial Access for Intra-Operative Cerebral Angiography during Prone Cerebrovascular Surgery [PDF]

Neurointervention
We reviewed our experience using transulnar access (TUA) to obtain intraoperative cerebral angiography during prone surgery for vascular pathology, where conventional transfemoral and transradial access can be difficult.
