We have recently reported the safety of intraventricular sodium nitroprusside for the treatment of cerebral ischemia from vasospasm. Treatments have been accompanied previously by cerebral angiography to gauge treatment effect on established vasospasm. We presently report the safe coadministration of intraventricular sodium nitroprusside and thiosulfate in 10 patients with secured ruptured cerebral aneurysms in the intensive care unit, without the use of cerebral angiography for vasospasm treatment. ⋯ Intraventricular sodium nitroprusside with thiosulfate may be safely administered in the intensive care unit setting without the requirement of cerebral angiography to guide the effects of therapy.

Active management of ruptured intracranial aneurysm in subarachnoid hemorrhage is indicated in patients with favorable prognosis. Outcome prediction is based on patient characteristics and clinical and radiological factors. Current clinical grading scales are imprecise, with low interobserver reproducibility. Therefore, outcome prediction remains inconsistent and decision making becomes difficult, especially for patients with poor clinical grade. ⋯ Apolipoprotein E epsilon4 genotype is related to poor outcome in patients with subarachnoid hemorrhage.

Temperature is a well-known modulator of experimental cerebral injury. We hypothesized that hyperthermia would be associated with a worsened cognitive outcome after coronary artery bypass graft surgery (CABG). ⋯ This is the first report relating postoperative hyperthermia to cognitive dysfunction after cardiac surgery. Whether the hyperthermia caused the worsened outcome or whether processes that resulted in the worsened cognitive outcome also produced hyperthermia requires further investigation. In addition, interventions to avoid postoperative hyperthermia may be warranted to improve cerebral outcome after cardiac surgery.

The objective of this study was to assess the health-related quality of life and symptoms of anxiety and depression in patients who are aware of the presence of a patent aneurysm or arteriovenous malformation. ⋯ Our study shows that knowledge of harboring an unoccluded untreated intracranial aneurysm or arteriovenous malformation reduces quality of life, most prominently on the psychosocial domains, without leading to substantially raised levels of anxiety and depression.

The National Institutes of Health Stroke Scale (NIHSS) is predictive of thrombus presence but has limited ability to identify occlusion location in the anterior circulation. We describe clinical and sonographic patterns that are associated with tandem internal carotid artery (ICA) and middle cerebral artery (MCA) occlusions. ⋯ Tandem ICA/MCA occlusion was found on TCD in 17% of TPA-treated patients. NIHSS scores were similar in patients with isolated MCA and tandem occlusions. Lower NIHSS scores were seen in patients with a higher number of major collateral flow channels and higher Thrombolysis in Brain Ischemia (TIBI) flow grades at the MCA origin.
