Does a fenestration anomaly require treatment?

Clinical fenestration anomaly refers to cerebral arterial fenestration malformation. Whether this type of anomaly requires treatment depends on a case-by-case evaluation and analysis.

Sometimes, the fenestration anomaly is merely an incidental imaging finding—for example, during cerebral angiography, a branch or main trunk of a cerebral artery may show fenestration. If it is not severe, causes no obvious clinical symptoms, and hemodynamics remain normal, then no treatment is necessary. In such cases, observation alone is sufficient, as this type of anomaly does not lead to serious consequences.

However, in some patients, cerebral arterial fenestration can be very severe, causing high pressure and even leading to intracranial ischemia or hemorrhage. When patients develop symptoms such as severe headache, slurred speech, and hemiplegia due to cerebral hemorrhage, they should seek prompt medical care. Treatment may include hemostatic agents, mannitol for dehydration, and neurotrophic agents such as trypsin-cerebroprotein hydrolysate. Once the patient's condition stabilizes, minimally invasive surgery or craniotomy is usually required to treat the cerebral arterial fenestration and prevent further hemorrhage caused by the vascular malformation.

In daily life, maintain a strict low-salt, low-fat diet, control blood pressure, blood glucose, and lipid levels, drink plenty of water, and avoid triggers such as colds and diarrhea. Regular monitoring of blood lipids, carotid ultrasound, transcranial Doppler, and head and neck CTA should be performed to evaluate cerebrovascular health.
