Occurrence of blocked small blood vessels in the head is mainly seen clinically in cerebral small vessel disease, which can be seen in lacunar cerebral infarction. Patients can have risk factors for cerebral atherosclerosis such as hypertension and diabetes mellitus, which are small vessel blockages caused by small vessel lesions. For the acute phase of treatment, patients can be given antiplatelet aggregation therapy with oral aspirin or clopidogrel, or they can be given intravenous Ozagrel sodium for injection. At the same time, the patient can be given drugs to improve cerebral blood circulation and activate blood stasis, such as injectable hemosiderin or thromboxane. After the acute phase, patients who show neurological deficits can be appropriately matched with rehabilitation. Six months after the occurrence of cerebral small vessel disease is also a golden period for rehabilitation, and patients are recommended to undergo systematic rehabilitation. At the same time, patients should initiate secondary prevention of cerebrovascular, with a low-salt and low-fat diet, control of risk factors, and regular review of cervical vascular ultrasound as well as biochemical tests.
