What is Cerebral Vascular Malformations?

Cerebral vascular malformations are congenital vascular anomalies in which abnormal connections between arteries and veins occur without an intervening capillary network (AVM) or in which small vessels form clusters (cavernoma).

AVMs may rupture and cause intracerebral or subarachnoid hemorrhage; some patients are diagnosed incidentally on imaging performed because of seizures or other reasons. Cavernomas tend to cause recurrent small bleeds and seizures.

Treatment decisions are made jointly with neurosurgery and interventional radiology specialists, depending on lesion size, location, age, and presence of symptoms.

Symptoms

Epileptic seizure
Sudden severe headache (if bleeding present)
Focal neurological findings (weakness, vision loss, speech disturbance)
Incidental radiologic finding (may be asymptomatic)
Recurrent headaches
Brainstem or cerebellar findings (depending on lesion location)

Risk Factors

Congenital vascular development anomaly
Family history of AVM or cavernoma
HHT (hereditary hemorrhagic telangiectasia) syndrome
Prior radiation therapy
Pregnancy (may increase risk of AVM bleeding)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • New-onset epileptic seizure
  • Sudden severe headache (suspected bleeding)
  • Focal neurological deficit (weakness, vision disturbance)
  • For treatment planning if found incidentally on imaging

Treatment Methods

01
Observation (in asymptomatic small lesions)
02
Surgical resection (in accessible lesions)
03
Stereotactic radiosurgery (Gamma Knife, CyberKnife)
04
Endovascular embolization (preoperatively in large AVMs)
05
Antiepileptic therapy for seizure control
