Is capillary malformation hereditary?
Capillary malformation may be sporadic or inherited in an autosomal dominant pattern.
What is the vein of Galen formed by?
Vein of Galen malformation (VGAM) results from an aneurysmal malformation with an arteriovenous shunting of blood. The congenital malformation develops during weeks 6-11 of fetal development as a persistent embryonic prosencephalic vein of Markowski; thus, VGAM is actually a misnomer.
Who is Galen vein of Galen?
The vein of Galen malformation (also known as VGAM or VOGM) is a rare congenital blood vessel malformation in the brain that develops prenatally. A vein of Galen malformation is a tangled mass of abnormal connection of the arteries and the median prosencephalic vein of Markowski.

Is vein of Galen (vogm) inherited?
Vein of Galen malformations are not inherited. There is currently no known cause of these malformations, but children with VOGMs are more likely to suffer from other types of arteriovenous malformations (AVMs), or blood vessel malformations.
How does a Galen malformation affect the body?
Vein of Galen Malformation. The malformation causes oxygen-rich blood to flow directly through this vein away from the brain instead of delivering blood to surrounding brain tissues. This rush of blood away from the brain puts pressure on the heart and lungs, often causing congestive heart failure or pulmonary hypertension .
What is a precursor vein of Galen?
It involves a large vein at the base of the brain that is formed early in gestation and is normally replaced by the vein of Galen. In children with this condition, high-pressure, high-speed blood from the arteries flows directly into this precursor vein, preventing a true vein of Galen from forming.
