Patient: I got cerebellar infarction in January 2010, dizziness, nausea and vomiting, numbness and stiffness on the left side of my face, and also hypertension and high blood pressure, etc. After a phase of treatment, I feel a little better, but still feel dizzy walking in the station, thick flesh at the corners of the mouth, numb tongue and speech inconvenience. What drugs are good? I also feel that two or three years ago, my whole body felt stiff and had difficulty moving, and now it is so severe that my whole back feels like a stone pressing down on me and I am tired of walking. I also have rheumatoid arthritis. Doctor: Hello, most of your symptoms can be explained by cerebellar infarction. It has been six months since the onset of the disease, and there is no special treatment at present, but I think you need to do further laboratory tests as well as imaging examinations to clarify whether the cerebral infarction is caused by atherosclerosis; to clarify the situation of the cerebral vessels inside and outside the skull, and whether there is cerebral vascular stenosis, and if there is stenosis, you need to deal with it in time, such as further cerebral angiography, and if necessary, stent implantation treatment. Because if there is cerebrovascular stenosis, then cerebral infarction will face a great risk of recurrence, and cerebral artery stenosis will develop to a certain degree, and once the artery is completely occluded, serious cerebral infarction will occur, with symptoms such as hemiplegia, aphasia and blindness. And once the cerebral artery is occluded, it will not be possible to do stenting treatment. Therefore, the most important thing is not what medication you are currently using, but further examination of cranial MRI, CT angiography, and taking aspirin to prevent recurrence is the most important thing. Also further check blood sugar, blood lipids, blood pressure, etc. and treat with appropriate medication. Patient: I was diagnosed with cerebral infarction in January this year, and I was discharged after medical treatment for nearly a month, but I still feel dizzy and can’t walk, and I have uninterrupted infusion, I am three high people, there is also atherosclerosis, no diabetes, the brain and vascular MRI done shows that the brain stem has an infarct hood left in January, the basal vessels are narrowed, and the posterior circulation is not good, the doctor said if the imaging is done, a stent can be done, which can relieve I don’t know what to do now, I’ve been sick for seven months and still haven’t seen any improvement, so I missed the best treatment period, and my family is not rich. I’m begging for your guidance, should I do it or not, is the benefit too great? Doctor: You have a brainstem infarct and basilar artery stenosis. Generally speaking, basilar artery stenosis and its onset require further treatment – stent implantation. Otherwise, aggravation of the stenosis or further development of the basilar artery to basilar artery occlusion can lead to serious consequences, and it is foreseeable that the chances of such serious consequences are high, and the opportunity for stent implantation will be lost with certain occlusion. You said that there is infarct foci in brainstem, usually brainstem infarction will lead to dizziness, facial numbness and abnormal pain sensation, so after stent implantation, the blood supply of posterior circulation can be improved, and dizziness and numbness should be improved more obviously. However, the infarct foci already formed in your brainstem will not disappear because of the stenting. So the existing symptoms will not disappear completely after the stenting, but there will be significant improvement. Because the brainstem is very sensitive to ischemia, releasing the existing stenosis will lead to relief of ischemia. In addition, I think it is very important that the most important purpose of having a stent is to prevent the next serious infarct event from occurring. Our principle is that the better the current condition of the patient, the more stenting is recommended; if the patient is currently bedridden, it is not recommended. Regarding your comment about generalized stiffness, a lack of clear correlation with cerebrovascular disease is considered. A separate consultation is needed. However, I feel that it should not be a major problem, that is to say, it will not have serious consequences if left unattended. Finally, whether stenting is definitely needed or not, or whether stenting is possible, needs to be determined by clear cerebral angiography images. This involves many factors such as the degree of stenosis, the shape of the stenotic segment, the presence or absence of angulation, the location of the stenosis, the condition of the collateral circulation, the condition of both sides of the stenosis, the vascular access, the relationship between the infarct and the stenosis, the patient’s general condition, and the economic situation. I am afraid that it is not clear by such communication alone.
