This patient’s medical history is relatively typical. You described it very carefully, and the diagnosis can basically be confirmed. First of all, according to the symptoms of dizziness, nausea, and vomiting you mentioned, the most common disease is caused by insufficient blood supply of the vertebral-basilar artery. The straightening of the right limb may be hemiplegia or myotonia. Combined with the inability of both eyeballs to look left, That is to say, by staring to the right, one can accurately locate the pons, which is the main part of the brainstem supplied by the vertebrobasilar artery. CT has confirmed the above. Infarctions in the left occipital lobe and right cerebellum are all due to vertebral-basilar infarction. It is caused by blockage of small arterial branches. The MRI you do should be combined with MRI angiography. It clearly shows that there are lesions in the bilateral vertebral arteries and the intracranial basilar artery. In fact, the vertebral-basilar artery is A herringbone-shaped blood vessel, the two vertebral arteries form a basilar artery in the skull. Generally speaking, this patient has had some minor blockages due to arteriosclerosis, plaque, and stenosis in the vertebrobasilar artery, and some important blood vessels may continue to be blocked, such as the two episodes of stretching his legs and eyes. Staring, if the blockage is not episodic but persistent, the condition is likely to worsen. Prevention and prevention of exacerbation are to treat the diseased blood vessels. It is recommended to do a 64-slice CTA (CT angiography) or directly do a DSA (whole brain angiography) to clarify the degree of vascular disease. If the stenosis does not exceed 50%, it can be treated with drugs. If it exceeds 70%, stent treatment is required. This type of examination and treatment is generally only available in tertiary hospitals with equipment and capabilities.
Finally, it is recommended to treat it as soon as possible, because brainstem infarction caused by blockage of this blood vessel is generally more serious than infarction in other parts. It will not only cause hemiplegia and aphasia, but also cause difficulty in swallowing, choking on drinking water, coma and even death.
