The lenticulostriate arteries (LSA) are small perforating arteries, with diameters ranging from 0.08–1.4 mm, which predominantly arise from the first segment of the middle cerebral artery (MCA) [1]. They provide vascular supply to the basal ganglia, which are involved in motor control, speech, reward and cognition [2]. Due to a lack of collateral blood supply, the LSA vascular territory is considered vulnerable to ischemia. Prior studies in ischaemic stroke patients found that additional infarct…
