MR Imaging in Pretruncal Nonaneurysmal Subarachnoid Hemorrhage
Background and Purpose—The cause of pretruncal (perimesencephalic) nonaneurysmal subarachnoid hemorrhage is not known. MRI of the brain or spine is often performed to exclude any other vascular abnormalities. Its diagnostic value is not known. Methods—We used MR imaging of the brain with routine sequences, gadolinium enhancement, and additional thin T1-weighted axial sections following a triple...
متن کاملCardiac Complication Following Subarachnoid Hemorrhage
Besides its severe neurological injuries, spontaneous subarachnoid hemorrhage (SAH) commonly causes cardiac complications. These complications could include three different aspects of cardiac diseases, that is, electrocardiographic abnormalities, myocardial injuries, and left ventricular dysfunction. These complications not only may lead to misdiagnosis of SAH as myocardial infarction, but also...
متن کاملVasospasm after subarachnoid hemorrhage: interest in diffusion-weighted MR imaging.
BACKGROUND AND PURPOSE Vasospasm secondary to subarachnoid hemorrhage (SAH) is responsible for severe ischemic complications. Although effective, angioplasty must be performed at a very early stage to produce any clinical recovery. Diagnostic investigations to assess arterial narrowing (transcranial Doppler, angiography) or cerebral perfusion (xenon CT, single-photon emission CT) do not provide...
متن کاملDiffusion- and perfusion-weighted imaging in vasospasm after subarachnoid hemorrhage.
BACKGROUND AND PURPOSE Better measures of cerebral tissue perfusion and earlier detection of ischemic injury are needed to guide therapy in subarachnoid hemorrhage (SAH) patients with vasospasm. We sought to identify tissue ischemia and early ischemic injury with combined diffusion-weighted (DW) and hemodynamically weighted (HW) MRI in patients with vasospasm after SAH. METHODS Combined DW an...
متن کاملSubarachnoid Hemorrhage.
Aneurysmal subarachnoid hemorrhage (SAH) is a neurological emergency with high risk of neurological decline and death. Although the presentation of a thunderclap headache or the worst headache of a patient's life easily triggers the evaluation for SAH, subtle presentations are still missed. The gold standard for diagnostic evaluation of SAH remains noncontrast head computed tomography (CT) foll...
متن کاملSubarachnoid Hemorrhage
Hospital Physician May 2007 31 S ubarachnoid hemorrhage (SAH) is a devastating acute neurologic emergency that follows rupture of a blood vessel into the subarachnoid space.1 SAH affects 21,000 to 33,000 persons per year in the United States,2 leading to significant morbidity and mortality. The 30-day mortality rate approaches 50%, and those who survive often suffer major neurologic morbidity.3...
