Superficial Cerebral Veins

Main Text

TERMINOLOGY

Abbreviations

• Superficial middle cerebral vein (SMCV)
• Deep middle cerebral vein (DMCV)
• Vein of Trolard (VofT)
• Vein of Labbé (VofL)
• Basal vein of Rosenthal (BVR)
• Superior, inferior sagittal sinus (SSS; ISS)
• Cavernous sinus (CS)
• Sphenoparietal sinus (SPS)
• Great cerebral vein [vein of Galen (VofG)]

Synonyms

• Cortical veins: Superficial or external veins

GROSS ANATOMY

Overview

• Highly variable in number and configuration
• Located within subarachnoid space (SAS), cisterns
• Organized anatomically into 3 groups (superior, middle, inferior)
• Superior group

8-12 superficial cortical veins

Follow sulci, ascend to convexity

Cross SAS

Pierce arachnoid and inner dura, join SSS at right angles
• Middle group

SMCV

– Inconstant, variable size/dominance

– Begins over surface of lateral (sylvian) fissure

– Collects numerous superficial veins from frontal, temporal, parietal operculae

– Curves anteromedially around temporal lobe

– Terminates in CS or SPS
• Inferior group

Orbital surface of frontal lobe drains superiorly to SSS

Temporal lobe, anterior cerebral veins anastomose with deep middle cerebral and basal veins

Basal vein (of Rosenthal)

– Begins near anterior perforated substance

– Receives anterior cerebral, DMCV tributaries (from insula, basal ganglia, parahippocampal gyrus)

– Curves posteriorly around cerebral peduncles

– Drains into great cerebral vein (VofG)
• 3 major named large anastomotic cortical veins

VofT : Major superior anastomotic vein

VofL : Major inferior anastomotic vein

SMCV : Major middle anastomotic vein

Anatomy Relationships

• Anastomotic veins

Have reciprocal relationship (if 1 is large, others typically smaller or absent)

Abundant anastomoses with each other, as well as deep (internal) cerebral veins, orbit, extracranial venous plexi

Vascular Territories

• Superior group

Cortical veins + SSS, ISS

Venous drainage territory

– Superolateral hemispheric surfaces

– Most of medial hemispheric surfaces between ISS and SSS

– Most of frontal lobes except for perisylvian area
