This is important because the relative isolation of the MCA territory leaves the cerebral hemisphere ipsilateral to the absent ICA susceptible to injury, due to lack of collateral flow from the circle of Willis. For example, in this case, occlusion of the right ICA could potentially cause infarct in the bilateral MCA territories.
