Vertebrobasilar syndrome cerebellar brainstem infarction is more dangerous. The vertebrobasilar artery gives off the posterior cerebral artery and the superior cerebellar artery, which supply blood to the cerebellum and brainstem. If an infarction occurs in this area, the patient is likely to experience symptoms such as difficulty swallowing, quadriplegia, choking on drinking water, respiratory and cardiac arrest, or even death, which is more dangerous. In vertebrobasilar syndrome cerebellar brainstem infarction, patients often need to take anti-platelet aggregation and anticoagulant drugs, such as aspirin, low molecular heparin, etc., to intervene, and also pay attention to controlling the risk factors, such as controlling hypertension, and some patients need to take endovascular interventional therapy or surgical treatment. Vertebrobasilar syndrome cerebellar brainstem infarction must be timely consultation, with the doctor to take treatment, to avoid delaying the condition, leading to serious adverse consequences.
