The inclusion criteria were clinical diagnosis of stroke or sinovenous thrombosis on the basis of detailed history, thorough neurological examination along with the evidence of ischemic or hemorrhagic damage or thrombosis in cerebral veins
on CT or MR scans.
It consists of superficial and deep cerebral veins
and dural sinuses.

and sinuses," Front Neurol Neurosci, vol.
Cerebral venous thrombosis (CVT) is a neurological emergency due to thrombus formation in the cerebral veins
The deep venous system includes the basal and internal cerebral veins
, great cerebral vein
(of Galen) and straight sinus, which drain the deep gray nuclei.

and sinuses," New England Journal of Medicine, vol.
Bilateral opacification of the internal cerebral veins
(arrows) and of the cortical (M4) segment of middle cerebral arteries (circled).
CT was read as multiple punctate curvilinear foci of hypoattenuation regional to the vein of Galen and deep cerebral veins
medial to the left thalamus and left occipital sulcus.
The most frequently observed incident is superior sagittal sinus thrombosis, and it is followed by transverse sinus, deep cerebral veins
and cavernous sinuses (10).
This is to prevent/minimize the further travel of air to the cerebral veins
and throughout the circulatory bed and organs.
However, they all keep cerebral veins
and venules at an arm's length.
