What is the cause of cerebral vascular malformation in children?

summary

Cerebral vascular malformations mainly include cerebral arteriovenous malformations and cystic aneurysms, which are the most common causes of primary subarachnoid hemorrhage in children. With the increasingly rich life now, many expectant mothers do not pay attention to the details of life during pregnancy, which leads to some influence on the children in the stomach and get sick. Cerebral vascular malformation in children is one of them. So, what is the cause of cerebral vascular malformation in children? Next, let's take a look at the causes of cerebral vascular malformations in children.

What is the cause of cerebral vascular malformation in children?

Cerebral arteriovenous malformations most often occur in two parts: the great cerebral vein (also known as Galen's vein) and the cerebral hemisphere vein. The great cerebral vein is located in the inferior and posterior part of the splenium of the corpus callosum and is formed by the confluence of the left and right internal cerebral veins. It is a short, thick, thin and fragile vein trunk, which runs from front to back and finally into the inferior sagittal sinus, The arteriovenous malformation of the great cerebral vein is the venous fistula between the posterior cerebral artery or the superior cerebellar artery and the great cerebral vein, which makes the arterial blood flow directly into the venous blood, thus producing a series of symptoms. The great cerebral vein malformation of the cerebral hemisphere is mostly located under the cerebral cortex, and its occurrence is mainly in the area supplied by the middle cerebral artery, and other parts such as the basal ganglia, Brain stem and cerebellum are also involved. Cerebrovascular malformations also include telangiectasia and cavernous hemangioma.

Cystic aneurysms are often ruptured at the base of the aneurysms when the diameter of the aneurysms reaches 6-15mm. The ruptured aneurysms can cause massive subarachnoid hemorrhage and subdural hemorrhage, The hemorrhage of cerebral parenchyma or ventricle cavity can form hematoma locally, compress brain tissue, and coexist with coarctation of aorta or congenital polycystic kidney.

Arteriovenous malformation, also known as congenital arteriovenous fistula, can be single or multiple in the brain. Arteriovenous malformation is mainly due to the lack of capillary development between the artery and the venous system, which directly forms a short circuit between the artery and the vein, resulting in the extremely enlarged arteries in the lesion supply area, and even the formation of aneurysm like malformation; Under the influence of intravascular pressure, the abnormal part gradually expands and finally oppresses the nearby brain tissue, leading to brain atrophy and easy to cause hemorrhage.

matters needing attention

These are the causes of cerebral vascular malformations in children. I believe you already know which causes of cerebrovascular malformation in children through the above reading. Then, we should take care of the baby carefully. If you have this kind of disease, treat it quickly. So as not to delay the treatment time.
