Is lacunar cerebral infarction serious?

summary

Lacunar infarction refers to the small perforating artery in the deep part of the cerebral hemisphere or brain stem. On the basis of long-term hypertension, vascular wall changes, leading to lumen occlusion, forming a small infarct. According to statistics, the incidence rate is quite high, accounting for 20% to 30% of cerebral infarction. The common sites were putamen, caudate nucleus, internal capsule, thalamus and pons, and a few were located in corona radiata and subependymal area. Is lacunar cerebral infarction serious? Let's talk about it

Is lacunar cerebral infarction serious?

The deep basal ganglia and brainstem are the important pathways of many nerve fiber tracts, and the bridge between brain and somatic nerve. If lacunar infarction occurs in these pathways, it will cause some nerve conduction block, resulting in motor, sensory or language disorders and other symptoms.

Because the lacuna is very small, sometimes it only affects the motor fibers or sensory fibers, resulting in pure motor hemiplegia, or only hemiparesis without hemiplegia. However, not all the lacunae will produce symptoms. Only those lacunae involving important neural pathways or neural structures will have symptoms, otherwise, there can be no symptoms.

General symptoms include dizziness, headache, numbness, vertigo, memory loss, slow reaction, convulsion, dementia, unconsciousness, and mental symptoms are rare. The main clinical signs were tongue stiffness, slow speaking speed, voice change, mild central facial paralysis, hemiplegia or sensory disturbance, positive pyramidal tract sign, and ataxia was rare.

matters needing attention

The blood pressure of patients with hypertension should be controlled at a reasonable level. Because the blood pressure is too high, it is easy to make the cerebral microangioma and atherosclerotic arteriole rupture and bleeding; When the blood pressure is too low, the cerebral blood supply is not complete, and the microcirculation is stagnant, it is easy to form cerebral infarction. Therefore, it is necessary to prevent various factors that cause sudden decrease of blood pressure, slow cerebral blood flow, increase of blood viscosity and increase of blood coagulation.
