Even after four decades of use, cerebral angiography continues to be a focus of controversy and misunderstanding among neurologists , surgeons, and neuroradiologists. Cerebral angiography is, or at least should be, performed solely by neuroradiologists and should be requested solely by neurologists, neurosurgeons, or vascular or cardiac surgeons after neurologic consultation. Most often at issu...

High-speed biplane angiography is used to determine the path and velocity of microdroplets of contrast material in three dimensions. By allowing more accurate determination of detailed blood flow in feeding vessels and draining veins of cerebral arteriovenous malformations than available with standard angiography, the new method offers the potential for more accurate treatment and further study...

PURPOSE No precise data are available showing how magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) can be applied to diagnosis for the first attack of a suspected cerebrovascular disease in Korea. The purpose of this study was to evaluate the application level of MRI and MRA as diagnostic tools and the related factors to the use of these techniques. MATERIALS AND METH...

A directional Doppler ultrasound cerebrovascular examination was compared with angiographical findings of 152 internal carotid arteries. The Doppler examination was abnormal in 36 of 38 (95%) arteries with occlusion or stenosis greater than 75%. Of 63 arteries with lesser degrees of stenosis, the Doppler examination identified only four. There were no false-positive Doppler examinations. If the...

Intraoperative angiography in cerebrovascular neurosurgery can drive the repositioning or addition of aneurysm clips. Our institution has switched from a strategy of intraoperative digital subtraction angiography (DSA) universally, to a strategy of indocyanine green (ICG) videoangiography with DSA on an as-needed basis. We retrospectively evaluated whether the rates of perioperative stroke, une...

BACKGROUND Both Alzheimer's disease (AD) and cerebrovascular atherosclerosis (CA) contributed to dementia in an aged population. Whether they share the same mechanism is unknown. AIM Our goal was to explore the occurrence rates of CA in AD patients. METHOD Here we examined the degree of CA in different groups of AD patients with contrast angiography. Ninety-three AD patients were recruited ...

Angiographically occult cerebrovascular malformation (AOVM) is a type of complex cerebrovascular malformation that is not visible on digital subtraction angiography (DSA). Vascular malformation coexisting with glioma is clinically rare, and glioma coexisting with AOVM is even more rare. To the best of our knowledge, the present study is the first to report glioma coexisting with AOVM in the lit...

Using autologous platelets labeled with indium-111-oxine, we studied the localization of platelets on arterial lesions by radionuclide scintigraphy in 34 patients with suspected cerebrovascular disease. The imaging results were compared with the findings of contrast angiography in 23 patients, 16 of whom were receiving antiplatelet and/or anticoagulant drugs during the platelet imaging study. A...

A 74-year-old man with a history of high blood pressure, smoking, and cerebrovascular accident 6 months ago was admitted to our center for chest pain radiating to back. The blood pressure was 140/95 mmHg and pulse was 88/minute. Physical examination revealed an apical systolic murmur. Laboratory tests including evidence of Behcet disease, connective tissue disease, or autoimmune form of vasculi...
