Current Perspective on the Role of the Thrombin Receptor in Cerebral Vasospasm After Subarachnoid Hemorrhage

Journal of Pharmacological Sciences, 2010
Cerebral vasospasm is a persistent arterial narrowing typically observed during the 3 – 14 days after subarachnoid hemorrhage (SAH). Vasospasm is frequently associated with ischemic neurological deficits or even death, resulting in a poor prognosis for ...

Verapamil use in interventional neuroradiology: A case series of postoperative pulmonary edema

Interdisciplinary Neurosurgery, 2020
Cerebral Vasospasm is a common complication of aneurysmal subarachnoid hemorrhage (aSAH) which results in delayed cerebral ischemia. Cerebral vasospasm in elective endovascular management of intracranial aneurysms rarely has been reported, and the ...

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

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.

Hyponatremia as predictor of symptomatic vasospasm in aneurysmal subarachnoid hemorrhage

Interdisciplinary Neurosurgery, 2020
Background: Subarachnoid hemorrhage is one of high morbidity in vascular neurology and neurosurgery and one of the clipart for this is symptomatic vasospasm that can leads to delayed cerebral ischemia.

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

Annals of Clinical and Translational Neurology, Volume 13, Issue 10, Page 2046-2056, October 2026.
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

Symptomatic cerebral vasospasm after glioblastoma resection and carmustine wafers implantation. A case report

Interdisciplinary Neurosurgery, 2018
Local chemotherapy with carmustine-impregnated wafers showed safe and effective in the treatment of malignant glioma, with infrequent, though sometime serious, adverse effects.We report a rare case of cerebral vasospasm following glioblastoma removal ...

Bedside Transcranial Doppler as a Dynamic Warning Tool for Rapidly Evolving Intracranial Hypertension in Pneumococcal Meningitis

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT In severe bacterial meningitis, an initially non‐critical or technically unreliable lumbar puncture opening pressure should not reassure when hydrocephalus and coma persist. Bedside transcranial Doppler cannot measure intracranial pressure, but bilateral near‐absent diastolic flow may provide an urgent warning signal prompting repeat ...

Double whammy: Delayed cerebral ischemia of a 19-year-old secondary to sinogenic complications from an uncommon bacterial sinusitis, Arcanobacterium haemolyticum

Radiology Case Reports
Arcanobacterium haemolyticum, found as normal flora in healthy individuals, is an unusual culprit for pharyngitis and sinusitis in young adults, rarely leading to severe infections. Here, we present a singular case involving a 19-year-old immunocompetent
