Early symptoms of traumatic cerebral infarction?

summary

Cerebral infarction caused by head injury is called traumatic cerebral infarction. This kind of disease is more common in adolescents, with a history of head injury, and the signs of nervous system localization mostly appear within 24 hours after injury. Cerebral angiography, CT or MRI can help to make a definite diagnosis. Early symptoms of traumatic cerebral infarction? Let's talk about it

Early symptoms of traumatic cerebral infarction?

When head injury occurs, the sudden extension and flexion of the head and neck will lead to the traction of the neck blood vessels, contusion of the blood vessel wall or damage of the intima; On the other hand, reflexivity causes vasospasm.

Vasospasm itself provides the possibility of thrombosis. At the same time, because of vascular injury, spasm, or thrombosis produce ischemic changes, the damaged vascular wall can become the site of delayed thrombosis. Thrombus enlargement or thrombus fall off, embolism of the basilar artery or posterior cerebral artery, resulting in cerebral infarction. In addition, traumatic cerebral infarction may be related to the formation of dissecting aneurysm.

Because of the impact of blood flow after traumatic injury, the intima and the middle layer of cerebral vessels are separated, resulting in the formation of dissecting aneurysms, progressive stenosis of vascular lumen, and eventually vascular occlusion. However, due to the imperfectness of brain development and the delicate blood vessels and other physiological and anatomical characteristics, mild traumatic attack can cause cerebral infarction due to the occlusion of deep perforating branches and branches of intracranial vessels.

matters needing attention

In daily life, we should take good care of the child. If the child is injured and has cerebral infarction, we must treat the child in time so that the child can recover early, so as not to leave sequelae.
