Physics-informed neural networks for improving cerebral hemodynamics predictions [PDF]

arXiv, 2021
Determining brain hemodynamics plays a critical role in the diagnosis and treatment of various cerebrovascular diseases. In this work, we put forth a physics-informed deep learning framework that augments sparse clinical measurements with fast computational fluid dynamics (CFD) simulations to generate physically consistent and high spatiotemporal ...

Distal Balloon Angioplasty of Cerebral Vasospasm Decreases the Risk of Delayed Cerebral Infarction

American Journal of Neuroradiology, 2019
A group of 392 patients was analyzed (160 before versus 232 after January 2015). Distal balloon angioplasty was associated with the following: higher rates of angioplasty (43% versus 27%) and intravenous milrinone (31% versus 9%); lower rates of ...

Transient cerebral hypoperfusion and hypertensive events during atrial fibrillation: a plausible mechanism for cognitive impairment [PDF]

Scientific Reports, 6: 28635, 2016, 2016
Atrial fibrillation (AF) is associated with an increased risk of dementia and cognitive decline, independent of strokes. Several mechanisms have been proposed to explain this association, but altered cerebral blood flow dynamics during AF has been poorly investigated: in particular, it is unknown how AF influences hemodynamic parameters of the distal ...

Management of cerebral vasospasm following aneurysmal subarachnoid hemorrhage

Southwest Respiratory and Critical Care Chronicles, 2017
Cerebral vasospasm is a serious complication following aneurysmal subarachnoid hemorrhage (SAH); it causes delayed cerebral ischemia (DCI) or infarction.

Integration of Clinical, Biological, and Computational Perspectives to Support Cerebral Autoregulatory Informed Clinical Decision Making Decomposing Cerebral Autoregulation using Mechanistic Timescales to Support Clinical Decision-Making [PDF]

arXiv, 2022
Adequate brain perfusion is required for proper brain function and life. Maintaining optimal brain perfusion to avoid secondary brain injury is one of the main concerns of neurocritical care. Cerebral autoregulation is responsible for maintaining optimal brain perfusion despite pressure derangements. Knowledge of cerebral autoregulatory function should

Matrix Metalloproteinases in Cerebral Vasospasm following Aneurysmal Subarachnoid Hemorrhage

Neurology Research International, 2013
Delayed cerebral vasospasm is a significant cause of morbidity and mortality following aneurysmal subarachnoid hemorrhage (SAH). While the cellular mechanisms underlying vasospasm remain unclear, it is believed that inflammation may play a critical role ...

Radio-frequency thermodestruction of jugular sympathetic ganglion in order to destruct vasoconstriction at subarachnoid aneurysmatic hemorrhage

Бюллетень сибирской медицины, 2008
The new method of cerebral vasospasm management is proposed. Selective radiofrequency thermodestruction of the cervical sympatethic ganglion at the С6 , С7 on the side of vasospasm has been performed.

Cerebral vasospasm in shunt infection [PDF]

Neurocritical Care, 2007
In bacterial shunt infection, CNS inflammation is a frequently observed complication that may cause vascular complications including vasospasms. Here, we describe the first patient with shunt infection-induced cerebral vasospasms.A 35 year old woman with a ventriculoperitoneal shunt that was implanted years before developed facial nerve palsy and ...

Preventive Effect of Clazosentan against Cerebral Vasospasm after Clipping Surgery for Aneurysmal Subarachnoid Hemorrhage in Japanese and Korean Patients

Cerebrovascular Diseases, 2017
Background: Clazosentan has been explored worldwide for the prophylaxis of cerebral vasospasm after aneurysmal subarachnoid hemorrhage (aSAH). In a dose-finding trial (CONSCIOUS-1) conducted in Israel, Europe, and North America, clazosentan (1, 5, and 15
