CAUSES OF INJURY
Stroke: occlusion of this vessel can lead to infarction of its perfused territories.
CLINICAL PRESENTATION OF INJURY
Contralateral somatosensory/motor deficits (predominantly of the lower extremity): given the perfusion territory of the ACA, both the motor and sensory cortex can be involved (and generally patients who have an issue with this vessel will present with symptoms more pronounced in the lower extremities).
