Computed tomography angiography findings predictive of post-intervention vasospasm in patients with aneurysmal subarachnoid hemorrhage.

Objective: To evaluate the association of CT/CT angiography (CTA) findings and clinical characteristics with subsequent vasospasm in patients with aneurysmal subarachnoid hemorrhage (aSAH).

Methods-: Consecutive presentation CTA head exams in patients with aSAH between January 2005 and June 2015 were retrospectively evaluated for intracranial arterial calcification, undulation and non-calcified stenosis. Additional variables including modified Fisher Scale (mFS), Glasgow Coma Scale (GCS) and neurological exam status were reviewed.

The Association of Intracranial Vascular Calcification and Stenosis With Acute Ischemic Cerebrovascular Events.

Objective: The aim of this article was to evaluate the association of intracranial artery calcification (IAC) with acute downstream ischemic stroke (dAIS)/transient ischemic attack while considering stenosis.

Methods: Consecutive stroke computed tomography angiography head/neck examinations from January 2010 to April 2010 were reviewed. Per-vessel IAC and stenosis of greater than or equal to 30% were documented by 2 neuroradiologists.
