Q28.1: Other malformations of precerebral vessels

Other malformations of precerebral vessels (Q28.1) refer to congenital abnormalities, meaning they are present at birth, found in the blood vessels that supply blood flow to the brain, prior to its division into cerebral arteries. These malformations include any structural problems with the vessels that affect their normal function, such as aneurysms or stenoses. Symptoms associated with these malformations can vary greatly and may remain unnoticed until an isolated incident causes them to be discovered. Many individuals with these malformations may experience headaches, seizures, stroke symptoms, or even bleeding in the brain. However, it must be noted that the specific symptoms, their severity, and possible complications heavily depend on the particular type and location of the malformation. This condition usually results from issues during the embryonic or fetal development of the vascular system.
