Often, left middle artery occlusion is not necessarily smoky disease.
Smokey’s disease, also known as spontaneous basilar artery ring occlusion or anomalous vascular network at the base of the brain, is a chronic cerebrovascular disease of unknown etiology, characterized by a slow thickening of the intima-media of the internal carotid arteries at the end of the internal carotid arteries and the anterior cerebral arteries, the beginning of the middle cerebral arteries and the gradual narrowing of the arterial lumens to the point of occlusion, with compensatory dilatation of the penetrating arteries of the brain base.
The diagnosis of smokers’ disease is based on bilateral middle cerebral artery stenosis or occlusion, resulting in an abnormal vascular network at the base of the brain. If only the left middle cerebral artery is occluded, it is impossible to diagnose smokers’ disease, so the left middle artery occlusion is not necessarily smokers’ disease.
Left middle cerebral artery occlusion may be embolism or atherosclerotic plaques. Which one is the cause needs to be judged together with the patient’s past medical history, current medical history and auxiliary examinations.
