Nineteen patients with severe stenosis or occlusion of the internal carotid artery (ICA) were reported, mainly progressive and episodic lower extremity weakness. The clinical, cerebral angiographic, and cerebral blood flow (CBF) measures were supported by hemodynamic pathophysiological mechanisms and in particular Due to the low perfusion of the artery border between the anterior cerebral artery (ACA) and the middle cerebral artery (MCA), it was divided into progressive weakness group (n = 8) and episodic weakness group (n = 11) With the onset of diabetes mellitus at the age of 38, all the remaining patients had neurological symptoms after 55 years of age with an average age of onset of 64.3 years (16 male 84.2%), 13 (68.4%) had a history of cerebrovascular disease 15
