The objective of the study was to use 320-detector row 4D CT angiography (CTA) for measuring cerebral circulation times (CCT) and to assess early venous drainage (EVD) and shortening of CCT in arteriovenous malformations (AVM) and to compare with DSA. CCT of 12 physiological patients and ...
jugular veins and superior sagittal sinus decreased, the perfusion pressure in the brain increased, the cerebral circulation time was accelerated, the consumption of by the brain and the arterio-venous difference in increased, and the acid-base condition and gases in the blood returned to normal ...

Cerebral aneurysmsare defined as dilations that occur at weak points along the arterial circulation within the brain. They can vary in size (small less than 0.5 mm, medium 6 to 25 mm, and large greater than 25 mm). Most aresaccular(berry), which...
③Conventional angiography is the “gold standard” for demonstrating the internal angioarchitecture. The carotid and vertebral circulation must be evaluated to exclude multiple feeding arteries. ③传统血管造影是显示其内部血管结构的“金...
- Stroke; a journal of cerebral circulation 被引量: 7发表: 2014年 Shortened Cerebral Circulation Time Predicts Resistance to Obliteration in High-Flow Brain Arteriovenous Malformations After Stereotactic Radiosurgery Treatment selection for brain arteriovenous malformations (BAVMs) is complicated by BAVM ...
In utero most of the AVM return would be shunted via the ductus away from the LV and down the descending aorta. Thus the LV would be relatively small and unprepared for the massive increase in flow associated with the ex-utero circulation and the descending aorta would be large. Our E ...
These include non-neoplastic lesions such as arteriovenous malformations (AVM), cavernous malformations (CM), developmental venous anomalies (DVA), and telangiectasias as well as others like arteriovenous fistulas (AVF), vein of Galen malformations (VOGM), and mixed or unclassified angiomas. These ...
Correlation of cerebral microvascular circulation with vital signs in cerebral compression and the validity of three concepts: vasodilation, autoregulation... Background: Vasodilation, autoregulation, and rising arterial pressure are three common concepts in cerebral compression, believed to improve cerebral ...
Cerebral veins of deep circulation and posterior fossa are shown in lateral view MR venography. Dominant structure of this system is great cerebral vein (of Galen), which is formed by joining of two internal cerebral veins, and basal cerebral vein of Rosenthal. Then it drains into straight ...
