Vascular supply of brain

BRANCHES OF INTERNAL CAROTID

Meningohypophyseal trunk (that “Italian artery” Bernasconi-Casanari)

Ophthalmic

Superior hypophyseal

Posterior communicating (infundibulum, connects to PCA)

Anterior choroidal (AChoA – marker for temporal lobe herniation)

Anterior cerebral (ACA)

- Frontopolar

- Callosomarginal

- Pericallosal

Middle cerebral (MCA)

- Lenticulostriate (perforators to basal ganglia)

Internal Carotid (ICA)

- Cervical-Petrous-Cavernous-Supraclinoidsegments

POSTERIOR CIRCULATION BRANCHES

Vertebral

- Muscular (occipital) branches

- Meningeal branch

- PICA

Basilar

- AICA

- Superior cerebellar (SCA)

- Posterior cerebral (PCA)

- Posterior communicating

- Posterior choroidal (medial/ and lateral branches)

- Parietoccipital

- Posterior temporal

- Calcarine

EXTERNAL CAROTID BRANCHES

Superior thyroid

Lingual

Facial

Ascending pharyngeal

Occipital

Posterior auricular

Superficial temporal

Internal maxillary

- Middle meningeal (f. spinosum)

DEEP VENOUS DRAINAGE

Anterior septal

Thalamostriate

Internal cerebral veins (paired)

Basal vein(s) of Rosenthal (medial temporal lobe)

Great vein of Galen

Inferior sagittal sinus (free edge of Falx)

Straight sinus

Superior sagittal sinus (don’t forget the “Torcular Herophilus”)

Transverse sinus

Sigmoid sinus

Internal jugular

COMMENT: Superficial drainage is superficial middle cerebral vein, vein of Trolard and vein of Labbe to superior sagittal sinus
