cerebral vasospasm fundus

Michael D Greenwood, Shawn C Wilker
PURPOSE: To report a case of central retinal artery occlusion that occurred during cerebral angiography for the treatment of vasospasm secondary to subarachnoid hemorrhage. RESULTS: Examination was notable for 20/Hand Motion vision and an afferent pupillary defect. Fundus examination at the time of the event revealed a cherry red spot typical of central retinal artery occlusion with surrounding edema of the retina and severe attenuation of the arterioles. There were no emboli noted...

OBJECTIVE: Coiling of aneurysms 3 mm in diameter or less has been associated with a relatively high rate of complications, including iatrogenic rupture. The present study aimed to determine the clinical outcome of our technique for coiling small aneurysms. METHODS: A retrospective chart review was performed of prospectively collected data for all patients who had endovascular coiling of an aneurysm 3 mm in diameter or less between 2003 and 2008. Follow-up imaging with magnetic resonance or catheter angiography was performed at varying intervals after coiling, ranging from 1 to 6 years after the procedure...

The prognosis of patients with early re-ruptured intracranial aneurysms is discouraging. We compared the data on patients suffering re-rupture before the onset of late vasospasm (Early-Re) with those suffering rebleeding thereafter (Late-Re). The operability in the Early-Re group was lower (p < 0.05) and the outcome less satisfactory than that of Late-Re group. Of the Early-Re patients, 83% had a re-rupture within 24 hours of the initial subarachnoid haemorrhage; moreover 46% of these experienced rebleeding within three hours of the initial bleeding...

Samples of cerebrospinal fluid (CSF) drawn from patients with subarachnoid hemorrhage, subdural hemorrhage, or brain tumor, as well as control samples from patients without a known cerebral pathological condition, were tested for their ability to contract smooth muscle. Canine middle cerebral artery, canine basilar artery, and rat stomach fundus were used, and contractions were expressed as the percentage of the contraction elicited by a standard dose of 5-hydroxytryptamine. All samples that contained blood produced contractions of the smooth muscle preparations, and despite a large sample no significant differences were observed in the magnitude of the contractions either between preparations or between samples from different groups of patients...

Cerebrospinal fluid (CSF) was collected preoperatively (by lumbar puncture) or perioperatively (by lumbar or ventricular drain) from 32 patients with subarachnoid hemorrhage (SAH) from ruptured intracranial aneurysms. Samples were also obtained from six control patients without evidence of subarachnoid blood. Smooth-muscle constrictor activity in the CSF was measured by bioassay using the isolated rat stomach fundus preparation. Concentrations of unidentified smooth-muscle constrictor substances were considerably greater in CSF from a group of seven patients with evidence of severe angiographic vasospasm and/or delayed ischemic deficits who died (73...
