Veins Flashcards
What veins connect the scalp veins to the intracranial venous sinuses?
Emissary veins
What are the draining veins of the orbit?
Superior ophthalmic vein
Inferior ophthalmic vein
both drain into the cavernous sinus
How is the IJV related in terms of position to the internal and common carotid arteries?
The IJV lies posterolateral to the internal and common carotid arteries
What are the 3 facial veins that eventually drain into the common facial v?
Anterior
Deep
Posterior
What plexus is inferoposterior to the cavernous sinus?
The basilar (clival) plexus
What conditions can cause filling of prominent scalp or emissary veins?
AVMs
Sinus pericranii
Increased ICP
Scalp or skull neoplasms
Where does the superior sagittal sinus originate?
Near the crista galli
What sinuses form the torcular Herophili?
Transverse sinuses, Superior sagittal sinus, Straight sinus
What converge to form the vein of Galen?
What converge to form the Straight sinus?
What converge to form the vein of Galen? Basal vein of Rosenthal and Internal cerebral veins
What converge to form the Straight sinus? Vein of Galen and the inferior sagittal sinus
What are the anatomic landmarks that mark the extent of the transverse sagittal sinus?
Internal occipital protuberance to the petrosal portion of the temporal bones
In nearly 75% of cases which transverse sinus is bigger?
The right
What sinuses does the superior petrosal sinus connect?
What about the inferior petrosal sinus?
Cavernous sinus and the sigmoid sinus
Cavernous sinus and drains into the jugular bulb
A true cavernous sinus lies on either side of the ______.
Sphenoid body
The intercavernous sinus surrounds what structure?
The sella
What is a vein of galen malformation?
Huge primitive median prosencephalic vein
Most of the cerebral venous development occurs during?
Third month of fetal life
What is the precursor of the deep cerebral veins?
Median prosencephalic vein
What is the precursor for the superior sagittal sinus and the transverse sinus?
Pair of primitive marginal sinuses extends from the
anterior dural plexus along both sides of the anterior cerebral
vesicle
What are the three main superficial veins?
- Superficial middle cerebral vein
- Superior anastomotic vein of Trolard
- The inferior anastomotic vein of Labbé
The internal cerebral veins and basal vein of rosenthal form?
The vein of Galen
The superficial middle cerebral vein drains into?
The cavernous sinus or the sphenoparietal sinus
What do the vein of labbe and trolard connect?
Trolard: SSS and SMCV
Labbe: Transverse sinus and SMCV
T or F: In general there is a reciprocal relationship
between the veins of Labbe and Trolard. If Trolard is dominant,
Labbe is usually small or absent
T
What two veins unite to form the thalamostriate vein?
What two veins unite to form the internal cerebral veins?
What two veins unite to form the vein of Galen?
Anterior caudate vein and terminal vein
Septal veins
Thalamostriate vein
Internal cerebral vein
Basal vein of Rosenthal
What group of veins drain the basal ganglia, internal capsule, medial temporal lobes?
Septal veins, Thalamostriate veins, Internal cerebral veins, Vein of Galen
What are the three groups of posterior fossa veins?
Superior (Galenic): Precentral cerebellar vein, superior vermian vein, anterior pontomesencephalic vein
Anterior (Petrosal): Petrosal vein
Posterior (Tentorial): inferior vermian vein
The precentral cerebellar vein and superior vermian vein drain directly into?
Vein of Galen
The inferior vermian vein drains into the?
Straight sinus
The petrosal vein (part of the anterior group of veins drains) into?
Superior petrosal sinus
