thalamic lacunar infarction

What is the reason for this, mainly because the patient's cerebral hemisphere, or deep brain branch arteries show occlusion, blood vessels due to relatively small, so like his infarction focus is also relatively small, diameter is 1.5 to two centimeters below, and these arterioles often belong to the terminal artery, collateral circulation is relatively poor, once infarction, there is no other blood vessels to compensate for his function. Clinical manifestations are mainly, for example, thalamic infarction will show hemiplegia or balance sensory disturbance, etc., other symptoms include dysphagia, but these symptoms are relatively mild, easy to be ignored by patients or family members. Treatment focuses on controlling these risk factors for cerebrovascular disease, especially hypertension and diabetes, which need to be effectively controlled. Other treatments, including antiplatelet therapy, can cause recurrence of such cerebral infarction if the patient is not controlled. Even frequent episodes of lacunar infarction may cause severe clinical symptoms.
