Cerebral saccular aneurysm rupture after head injury.

When seen after head trauma, subarachnoid hemorrhage (SAH) often leads to an angiogram to look for vascular injury. Usually the study is negative; sometimes a traumatic aneurysm or dissection is seen. Occasionally, a conventional saccular aneurysm is found. The clinical history, physical examination, and computed tomography (CT) scan in such a patient may suggest that an aneurysmal SAH was the ...

Changes in local cerebral glucose utilization during rewarding brain stimulation.

The quantitative 2-deoxy[14C]glucose method was used to determine local cerebral glucose utilization in unrestrained rats responding (lever-press) for rewarding electrical stimulation to area A10 (ventral tegmental area) and in similarly implanted inactive controls. Self-stimulation was associated with significant increases in metabolic activity, highly circumscribed in the ventral tegmental ar...

Cerebral endothelial damage after severe head injury.

We demonstrate that in head injuries the degree of cerebral endothelial activation or injury depends on the type of brain injury and the patients age, and that in severe head injuries measuring the serum levels of thrombomodulin (TM) and von Willebrand factor (vWF) is useful in evaluating cerebral endothelial injury and activation. The values of vWF in the cases of focal brain injury were signi...
