The vascular territories of groups of perforating vessels using a selective injection
method9).
Left: The axial section through the genu and splenium of the corpus callosum. Lenticulostriate
artery (LSA) supply lateral and superior part of the head of the caudate nucleus,
while medial and inferior part are supplied by anterior cerebral artery (ACA) perforators.
The LSA also supply almost the entire anterior limb of the internal capsule, putamen,
and proximal part of the posterior limb of the capsule. The distal half or two-thirds
of the posterior limb and the retrolenticular portion of the internal capsule are
supplied by anterior choroidal artery (AChA) perforators.
Right: The axial section through the inferior part of the superior colliculus. LSA
supply the lateral and posterior part of the putamen, and the posterior part of the
lateral segment of the globus pallidus. The ACA perforators perfuse the entire head
of the caudate nucleus and the anterior limb of the internal capsule, the anterior
and medial part of the putamen, the anterior part of the globus pallidus and the medial
part of the anterior commissure. The AChA perforators nourish almost the entire posterior
limb, the retrolenticular portion of the internal capsule, the optic tract and the
adjacent part of the cerebral peduncle. The ACA perforators perfuse the anterior and
inferior part of the putamen, and the nucleus accumbens.
The territory of the ACA is presented in yellow, the middle cerebral artery (MCA)
in red and the AChA in blue.
