basal vein


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

ba·sal vein

[TA]
a large vein originating from the confluence of veins from the orbital cortex (anterior cerebral veins [TA]) and the area of the insular cortex [deep middle cerebral vein [TA] (vena media profunda cerebri [TA]), insular veins [TA] (venae insulares [TA])], and passing caudally and dorsally along the medial surface of the temporal lobe, eventually emptying into the great cerebral vein. The basal vein receives tributaries from structures along its course; these include vein of olfactory gyrus [TA] (vena gyri olfactori [TA]), inferior thalamostriate veins [TA] (venae thalamostriatae inferiores [TA]), inferior ventricular vein [TA] (vena ventricularis inferior [TA]), inferior choroid vein [TA] (vena choroidea inferior [TA]), and peduncular veins [TA] (venae pedunculares [TA]).

A vein along the base of the brain that runs from the cavernous sinus, around the cerebral peduncle, and into the vein of Galen. Tributaries of the basal vein include the anterior cerebral, deep middle cerebral, and striate veins.

Stripe-shaped hyperintensity on MR T1-weighted imaging is a sign of cerebral cortical venous thrombosis.[3] In this case, the high punctiform signal in the left ambient cisterna on MR T1-weighted imaging indicated a diagnosis of venous thrombosis, which was further supported by the absence of the left basal vein in magnetic resonance venography and a good response to anticoagulant therapy.
