What is moyamoya disease

First, moyamoya disease is also called abnormal vascular network at the bottom of the brain in medicine. This disease is a group of cerebrovascular diseases characterized by stenosis or occlusion of the siphon part of the internal carotid artery and the initial part of the anterior and middle cerebral arteries, and abnormal small vascular network at the bottom of the brain. Because cerebral angiography presents a lot of dense piles of small vascular shadow, like smoking smoke, so it is called moyamoya disease.

Second, moyamoya disease usually occurs in adolescents or children, often in the form of stroke, which can be manifested as cerebral thrombosis, cerebral hemorrhage and subarachnoid hemorrhage. Patients may have different degrees of hemiplegia, or paralysis on the left and right sides, accompanied by aphasia, drinking water cough, dysphagia, mental retardation, dementia, epilepsy, headache and transient ischemic attack.

Third, in patients with moyamoya disease, cerebral angiography can show stenosis or no development of the initial part of internal carotid artery, anterior and middle cerebral artery, and a large number of small blood vessels in the basal ganglia, such as smoke from smoking. In addition, compensatory collateral circulation was formed in the brain. The number of compensatory anastomotic branches decreased with the course of disease.

matters needing attention

Patients with moyamoya disease should strengthen physical exercise. For patients with paralysis, more attention should be paid to the rehabilitation training of limbs. For patients with subarachnoid hemorrhage, they should not move the patient to avoid coughing, sneezing, breath holding defecation and other actions that increase the pressure of chest and abdominal cavity.
