Publicationdate November 24, Knowledge of the vascular territories is important, because it enables you to recognize infarctions in arterial territories, in watershed regions and also venous infarctions. It also helps you to differentiate infarction from other pathology.

Brain Ischemia - Vascular territories

Branches from vertebral and basilar artery These branches supply the medulla oblongata in blue and the pons in green. Anterior Choroideal artery AchA in blue The territory of the AChA is part of the hippocampus, the posterior limb of the internal capsule and extends upwards to an area lateral to the posterior part of the cella media.

Their territory includes most of the basal ganglia. The medial LSA' s indicated in dark red arise from the anterior cerebral artery usually the A1-segment. Heubner's artery is the largest of the medial lenticulostriate arteries and supplies the anteromedial part of the head of territorios vasculares cerebrales caudate and anteroinferior internal capsule.

Anterior cerebral artery ACA territorios vasculares cerebrales red The ACA supplies the medial part of the frontal and the parietal lobe and the anterior portion of the corpus callosum, basal ganglia and internal capsule. Middle cerebral artery MCA in yellow The cortical branches of the MCA supply the lateral surface of the hemisphere, except for the medial part of the frontal and the parietal lobe anterior cerebral arteryand the inferior part of the temporal lobe posterior cerebral artery.

The deep penetrating LSA-branches are discussed above. Posterior thalamoperforating arteries branch off the P1 segment and supply blood to the midbrain and thalamus.

Cortical branches of the PCA supply the inferomedial part of the temporal lobe, occipital pole, visual cortex, and splenium of the corpus callosum. On the left a detail to illustrate the vascular supply to the basal ganglia. Notice the posterior extention.

The infarction was the result of a dissection blue arrow. In unilateral infarcts there is always a sharp delineation in the midline because the superior vermian branches do not cross the midline, but territorios vasculares cerebrales a sagittal course.

This sharp delineation may not be evident until the late phase of infarction. In the early phase, edema may cross the midline and create diagnostic difficulties. Infarctions at pontine level are usually paramedian and sharply defined because the territorios vasculares cerebrales of the basilar arery have a sagittal course and do not cross the midline.

Bilateral infarcts are rarely observed because these territorios vasculares cerebrales do not survive long enough to be studied, but sometimes small bilateral infarcts can be seen. SCA On the left MR-image of a cerebellar infarction in the region of the superior cerebellar artery and also in the brainstem in the territory of the PCA.

Notice the limitation to the midline. Infarction of right hippocampal region courtesy Frederik Barkhof Anterior choroidal artery The anterior choroidal artery originates from the internal carotid artery.

territorios vasculares cerebrales Rarely it arises from the middle cerebral artery. The territory of the anterior choroidal artery encompasses part of the hippocampus, the posterior limb of the internal capsule and extends upwards to an area lateral to the posterior part of the cella media.

The whole area is rarely involved in AChA infarcts. The posterior limb of the internal capsule also receives blood from territorios vasculares cerebrales lateral lenticulostriate arteries.
