This aspect aligns with Li Jingsheng's diagnostic direction.
Based on the previous head examination results of the patient, it can be basically determined that her head blood vessels are more abundant than those of a normal person. However, it is not clear whether there is any abnormality or malformation.
Now with the DSA examination, obvious lesions have been discovered.
The supraclinoid segment of the patient's internal carotid artery bed shows significant stenosis, and near the anterior and middle cerebral arteries, there is even partial blockage.
The distal segment of the basilar artery is similarly blocked.
Seeing this, Li Jingsheng finally understands why the patient's bilateral head vessels are far more abundant than normal.
When arterial vessels become stenosed or even blocked, the brain is forced to cause changes in the terminal vessels to ensure sufficient blood supply.
