Yes, an infarct can grow. Infarct growth, especially in the brain, is thought to progress at different speeds across individuals. This variation is evident in patients with occlusions of the proximal middle cerebral artery (MCA) or internal carotid artery (ICA) terminus, who present with widely variable stroke volumes independent of the time after symptom onset.
In other words, even if the time elapsed since the onset of symptoms is similar among different patients, the size of the infarct can vary significantly, suggesting that infarct growth rates differ. This indicates that an infarct isn't a static entity and can evolve over time.
