What is a Vascular Malformation?
Left untreated, AVM's can enlarge, and rupture causing intracerebral or subchronid hemorrhage and permanent brain damage
What is the treament?
- Direct removal using microsurgical techniques
- Stereotactic radiosurgery: uses computer guidance to concentrae radiation to malformed vessels to the brain
- Embolization using neuroendovascular techniques
What is Moyamoya Disease
Moyamoya cones from the Japanese word for "puff of smoke" due to the appearance of the lesions that form
Moyamoya affects people of the Japanese origin far more often than the general population.
Children affected with Moyamoya Disease may have strokes, TIA'S seizures, and involuntary movement.
Moyamoya Disease is treated by either
- Encephalodurarteriosynangios (EDA)
- Encephalomyosynangios (EMS)
- Super-ficial temporal artery middle cerebral therapy (STA-MCA)
- Multiple Burr holes
Vein of Gealen Malformation
Rarer than AVM's, VGM can sometimes be determined by prenatal ultrasound
, or through cardiac failure in infants. Occurs during embryonic development so it's a congenital birth defect.
