Patient's question:
The child is only 7 months old. When he was born, it was said that he had a brain hemorrhage, but he has fully recovered. My sister was told to wait a year before re-examination. Last month, my sister took her son for a thorough check-up. The doctor conducted various tests and found that there was a dilatation in the large cerebral vein.What assistance is needed: What could have caused the dilatation in the child's large cerebral vein? Is it harmful to his health?
Doctor's answer:
The great cerebral vein is brought in by the venous system flowing through the intermediate structures of the choroid plexus. Initially, this vein does not communicate with the deep cerebral internal vein. The posterior part of the vein communicates with the cerebral internal vein, forming the great cerebral vein. The anterior part of the vein atrophies and eventually disappears. During the 6th to 11th weeks of embryonic development, if, for some reason, abnormal embryonic development occurs, the anterior part of the brain vein cannot atrophy normally or there is difficulty in communication, an arteriovenous fistula may be formed.
