Recurrent artery of Heubner

Recurrent artery of Heubner, also known as the medial striate artery or long central artery, is the largest perforating branch from the proximal anterior cerebral artery (ACA), and is the only one routinely seen on angiography.

Gross anatomy

Origin and course

Its origin is near the A1-ACOM-A2 junction of the ACA, arising from the proximal A2 in 90% of cases, and from the distal A1 in 10% of cases. It then curves back sharply on itself, paralleling the A1 and is at risk from ACOM aneurysm clipping (see case 1).

Supply

It supplies the head of caudate nucleus, paraterminal gyrus, anterior portion of the lentiform nucleus and anterior limb of the internal capsule.

Variant anatomy

It may be absent in 3% or duplicated in 12% of individuals.

History and etymology

It is named after Johann Otto Leonhard Heubner: German paediatrician (1843-1926).
