Deep Learning-based Segmentation of Cerebral Aneurysms in 3D TOF-MRA using Coarse-to-Fine Framework [PDF]

arXiv, 2021
BACKGROUND AND PURPOSE: Cerebral aneurysm is one of the most common cerebrovascular diseases, and SAH caused by its rupture has a very high mortality and disability rate. Existing automatic segmentation methods based on DLMs with TOF-MRA modality could not segment edge voxels very well, so that our goal is to realize more accurate segmentation of ...

Novel application of near-infrared spectroscopy in detecting iatrogenic vasospasm during interventional neuroradiological procedures

Brain Circulation, 2019
One of the complications of carotid artery stenting (CAS) is iatrogenic vasospasm caused by mechanical irritation of the blood vessel lumen by a guidewire, catheter, stent retriever, or distal protection devices.

Curcumin mitigates cerebral vasospasm and early brain injury following subarachnoid hemorrhage via inhibiting cerebral inflammation

Brain and Behavior, 2017
Subarachnoid hemorrhage (SAH)‐induced cerebral vasospasm and early brain injury is a fatal clinical syndrome. Cerebral vasospasm and early brain injury are associated with inflammatory response and oxidative stress.

Endovascular management of cerebral vasospasm [PDF]

Neurosurgical Focus, 2014
Cerebral vasospasm remains a feared complication from subarachnoid hemorrhage. Vasospasm typically occurs from three to fourteen days post–aneurysm rupture, with peak risk on Day 7. Up to 50% of patients with angiographic vasospasm will subsequently develop delayed cerebral ischemia; 15–20% of this subset will develop stroke or death despite maximal ...

Drug treatment of cerebral vasospasm after subarachnoid hemorrhage following aneurysms

Chinese Neurosurgical Journal, 2016
Cerebral vasospasm (CVS) is a common and severe complication of aneurysmal subarachnoid hemorrhage (aSAH). Despite the improvement in treatment of aSAH, CVS complicating aSAH has remained the main cause of death.
