Cerebral venous vascular malformations usually do not require treatment if there are no clinical symptoms.
Cerebral venous malformations, also known as venous angiomas. They are usually categorized into developmental venous anomalies and isolated varicose veins. Cerebral venous vascular malformations can be typically without typical clinical manifestations for a long time. As the disease progresses, lesions occurring supratentorially may present with chronic headaches, seizures, motor deficits, sensory disturbances, and other discomforts. Subtentorial lesions may present with symptoms such as gait instability.
Most patients are asymptomatic, and their natural prognosis is good and they do not require treatment. If the venous malformation is combined with a cavernous vascular malformation, surgical excision of the cavernous vascular malformation is required, but it should be handled with care, avoiding removal of the venous malformation surrounding the lesion as much as possible. If the venous malformation is inadvertently damaged, it is easy to cause bruising, swelling and necrosis of brain tissue.
It is recommended that patients with cerebral venous malformations seek medical attention in a timely manner, and the doctor will make a comprehensive assessment to determine whether the patient needs treatment.
