Visual field defects produced by basilar artery ectasia.

Abstract

The authors report two cases of visual field defects which are postulated to be due to the distal end of an elongated basilar artery compressing the visual pathways in the posterior suprasellar region. The mechanism of production of these defects is discussed, relating the abnormal position of the distal end of the basilar artery to a normally situated or only slightly post-fixed optic chiasm and optic tract and to a markedly post-fixed optic chiasm.

Stress-strain behavior of the passive basilar artery in normotension and hypertension.

Vascular cells are very responsive to even subtle changes in their local mechanical environment, thus there is a pressing need to quantify normal states of stress and strain as well as any perturbations from these normal states. Toward this end, we must quantify constitutive behaviors for both normal and adapted (maladapted) arteries. In this note, we report the first quantification of changes in the biaxial mechanical behavior of the passive basilar artery due to hypertension.

Ruptured intracranial aneurysm following gamma knife surgery for acoustic neuroma.

A-63-year-old woman underwent gamma knife surgery (GKS) for acoustic neuroma. Six years later, she suffered sudden onset of severe headache followed by a disturbance of consciousness and subarachnoid haemorrhage due to a ruptured aneurysm originating from the distal anterior inferior cerebellar artery. The aneurysm was not located at a branching site and was included within the radiation field. The aneurysm was treated by endovascular embolization, and now, 15 months later, the patient has recovered satisfactorily. This is the first report of aneurysm formation following GKS for acoustic neuroma.
