Deep learning-based multiclass segmentation in aneurysmal subarachnoid hemorrhage. [PDF]

Front Neurol
IntroductionRadiological scores used to assess the extent of subarachnoid hemorrhage are limited by intrarater and interrater variability and do not utilize all available information from the imaging. Image segmentation enables precise identification and

Prophylactic management of cerebral vasospasm with clazosentan in real clinical practice: a single-center retrospective cohort study

Frontiers in Neurology
IntroductionClazosentan, a selective endothelin receptor subtype A antagonist, reduces vasospasm-related morbidity and all-cause mortality following aneurysmal subarachnoid hemorrhage (SAH) in the Japanese population, as demonstrated by a recent ...

Hyperacute pathophysiology of traumatic and vascular brain injury captured by ultrasound, photoacoustic, and magnetic resonance imaging [PDF]

arXiv, 2022
Cerebrovascular dynamics and pathomechanisms that evolve in the minutes and hours following traumatic vascular injury in the brain remain largely unknown. We investigated the pathophysiology evolution within the first three hours after closed-head traumatic brain injury (TBI) and subarachnoid hemorrhage (SAH), two common traumatic vascular injuries, in

The pivotal role of microglia in injury and the prognosis of subarachnoid hemorrhage

Neural Regeneration Research
Subarachnoid hemorrhage leads to a series of pathological changes, including vascular spasm, cellular apoptosis, blood–brain barrier damage, cerebral edema, and white matter injury. Microglia, which are the key immune cells in the central nervous system,

A Case of Sudden Death: Subarachnoid Hemorrhage, Pheochromocytoma, Berry Aneurysm

Case Reports in Pathology, 2019
Subarachnoid hemorrhage is a medical emergency. Berry aneurysm rupture is the second most common cause following trauma. Diagnosis is often challenging. Neurogenic heart syndrome often complicates subarachnoid hemorrhage.

Dynamic expression of nerve growth factor and its receptor TrkA after subarachnoid hemorrhage in rat brain

Neural Regeneration Research, 2016
Delayed ischemic neurologic deficit after subarachnoid hemorrhage results from loss of neural cells. Nerve growth factor and its receptor TrkA may promote regeneration of neural cells, but their expression after subarachnoid hemorrhage remains unclear ...

Pseudo-subarachnoid hemorrhage and gadolinium encephalopathy following lumbar epidural steroid injection

Radiology Case Reports, 2020
Patients with imaging findings concerning for subarachnoid hemorrhage, however, with no evidence of hemorrhage following autopsy or cerebrospinal fluid testing are diagnosed with having pseudo-subarachnoid hemorrhage.

Comparing Conventional and Deep Feature Models for Classifying Fundus Photography of Hemorrhages [PDF]

, 2022
Diabetic retinopathy is an eye-related pathology creating abnormalities and causing visual impairment, proper treatment of which requires identifying irregularities. This research uses a hemorrhage detection method and compares classification of conventional and deep features.

Terson’s syndrome: A report of two cases [PDF]

Srpski Arhiv za Celokupno Lekarstvo, 2015
Introduction. Vitreous or retinal hemorrhage occurring in association with subarachnoid hemorrhage is known as Terson’s syndrome. In Terson’s syndrome, intracranial hemorrhages are followed by intraocular hemorrhage, classically in the ...

A mathematical model of the metabolic and perfusion effects on cortical spreading depression [PDF]

PLoS ONE 8(8) (2013), 2012
Cortical spreading depression (CSD) is a slow-moving ionic and metabolic disturbance that propagates in cortical brain tissue. In addition to massive cellular depolarization, CSD also involves significant changes in perfusion and metabolism -- aspects of CSD that had not been modeled and are important to traumatic brain injury, subarachnoid hemorrhage,
