Aspirin for primary prevention of stroke in traumatic cerebrovascular injury: association with increased risk of transfusion.

Objective: Blunt traumatic extracranial carotid or vertebral artery injury (i.e., traumatic cerebrovascular injury [TCVI]) occurs in 1%-2% of all blunt trauma admissions, carries a 10% risk of thromboembolic ischemic stroke, and accounts for up to 9600 strokes annually in the US.

Recrudescence of Symptoms of Remote Ischemic Stroke After a Cerebral Angiogram.

Background: Ischemic stroke recrudescence, or reappearance of previously resolved symptoms of ischemic stroke, may occur after physiologic stress. Although generally thought to be uncommon, this syndrome may account for a significant proportion of stroke mimics.

Case Description: A 67-year-old man was admitted with a Hunt and Hess grade 2 spontaneous subarachnoid hemorrhage.

C1-C2 cryptic cerebrospinal fluid leak directly identified by pressurized radionuclide cisternography: Case report and review of the literature.

Background: Patients with chronic postural headaches may suffer from spontaneous intracranial hypotension (SIH). Trauma, degenerative disc spurring and connective tissue disorders are documented risk factors; in most cases there is no inciting event. Despite sophisticated means of evaluating the neuraxis, many cerebrospinal fluid (CSF) leaks are radiographically occult and treatment is focused on thoracic and cervical-thoracic regions.
