Dynamic CT perfusion imaging in subarachnoid hemorrhage-related vasospasm.
BACKGROUND AND PURPOSE Nimodipine is a therapy that reduces morbidity and mortality in patients with subarachnoid hemorrhage (SAH), though the mechanisms by which it does so are not well understood. In a rabbit model of SAH, we studied the effects of nimodipine by using functional CT imaging. We hypothesized that the nimodipine treatment group would have (1) increased mean basilar artery diamet...
متن کاملVasospasm after subarachnoid hemorrhage: utility of perfusion CT and CT angiography on diagnosis and management.
PURPOSE To evaluate the utility of perfusion CT (PCT) combined with CT angiography (CTA) for the diagnosis and management of vasospasm, by using conventional digital subtraction angiography (DSA) as the gold standard. METHODS We retrospectively identified 27 patients with acute subarachnoid hemorrhage who had undergone CTA/PCT, DSA, and transcranial Doppler (TCD) ultrasonography within a time...
متن کاملCT angiography and perfusion CT in cerebral vasospasm after subarachnoid hemorrhage.
BACKGROUND AND PURPOSE We investigated the association of multisection CT angiography (MSCTA) and perfusion CT (PCT) for the characterization of vasospasm secondary to aneurysmal subarachnoid hemorrhage. MATERIALS AND METHODS Among 27 patients with symptomatic cerebrovascular vasospasm investigated by digital subtraction angiography (DSA), 18 underwent both cerebral PCT and MSCTA. For the rem...
متن کاملUsing quantitative CT perfusion for evaluation of delayed cerebral ischemia following aneurysmal subarachnoid hemorrhage.
BACKGROUND AND PURPOSE DCI is a serious complication following aneurysmal SAH leading to permanent neurologic deficits, infarction, and death. Our aim was to prospectively evaluate the diagnostic accuracy of CTP and to determine a quantitative threshold for DCI in aneurysmal SAH. MATERIALS AND METHODS Patients with SAH were prospectively enrolled in a protocol approved by the institutional re...
متن کاملRegional myocardial perfusion after experimental subarachnoid hemorrhage.
BACKGROUND AND PURPOSE The pathophysiology of cardiac injury after subarachnoid hemorrhage (SAH) remains controversial. Data from animal models suggest that catecholamine-mediated injury is the most likely cause of cardiac injury after SAH. However, researchers also have proposed myocardial ischemia to be the underlying cause, as a result of coronary artery disease, coronary artery spasm, or hy...
