Death Due to Cerebral Vasospasm.
It is accepted by many that vasospasm occurring as a result of ruptured intracranial aneurysm may contribute to the death of the patient. In the present case, although widespread spasm in the intracranial circulation was demonstrated, no aneurysm could be found either in life or at necropsy. The cause of the spasm is not known but its effects on the brain were undoubtedly responsible for death....
متن کاملEffect of increased intracranial pressure on cerebral vasospasm in SAH.
INTRODUCTION Increased ICP is common and might precipitate cerebral vasospasm (VSP)-induced ischemic events in aneurysmal SAH (ASAH).Our objective was to determine if there is an association between increased ICP and transcranial colour coded Doppler-angiographic VSP (TCCD-A VSP) in relation to delayed neurological deficit (DND) and poor outcome. METHODS A retrospective study was undertaken i...
متن کاملRegional cerebral blood flow in vascular depression assessed by 123I-IMP SPECT.
OBJECTIVE As the prevalence of white matter hyperintensities detected on T2 weighted MRI scans in patients with late-onset depression is higher than that in nondepressed patients, the concept of"vascular depression" (VDep) was introduced in 1997. However, the pathology of vascular depression has not been clarified. This study examined the differences in functional imaging between vascular and n...
متن کاملEvaluation of cerebral vasoreactivity by SPECT and transcranial Doppler sonography using the acetazolamide test.
rCBF SPECT with 99mTc-HMPAO was performed prospectively in 29 patients (3 controls and 26 stroke patients) as well as TCD studies in 20 patients (3 controls and 17 stroke patients) before and after 1 g i.v. acetazolamide. The sensitivity of rCBF SPECT increased from 62% to 77% after acetazolamide provocation in stroke patients. In patients with a reversible neurological deficit, the sensitivity...
متن کاملInflammation, Cerebral Vasospasm, and Evolving Theories of Delayed Cerebral Ischemia
Cerebral vasospasm (CVS) is a potentially lethal complication of aneurysmal subarachnoid hemorrhage (aSAH). Recently, the symptomatic presentation of CVS has been termed delayed cerebral ischemia (DCI), occurring as early as 3-4 days after the sentinel bleed. For the past 5-6 decades, scientific research has promulgated the theory that cerebral vasospasm plays a primary role in the pathology of...
