Venous Angioma

Definition

A venous angioma — also called venous malformation — of the brain is a small tangle of abnormal veins. Venous angiomas are the most common brain vascular malformation, occurring in approximately 2 percent to 3 percent of people.

Symptoms

The possible symptoms of venous angioma are :-

• The hemmorage can be seen in the patient of venous angioma.
• Feeling of headache.
• A venous angioma patient experiences lazy ness in doing work.
• The Spider, Cherry and Senile angiomas may be seen during venous angioma.
• The nausea and vomiting
• The insomnia is a earliest and most common symptom of venous angioma.
• Feeling of weakness in both limbs.

Treatment

Treatment of Venous Angiomas is very difficult. Most times individuals will not even know that they have this illness, since symptoms do not always present themselves. If it is discovered, usually doctors take a stand of monitoring it over a period of time. There are three main ways to treat an AVM:

• surgical removal
• stereotactic radiosurgery (Gamma Knife)
• endovascular embolization

Smaller cavernous angiomas are somewhat difficult to detect. Insist that one of your MRI sequences consists of “gradient-echo” (as opposed to spin-echo or proton beam) imaging. Gradient-echo MRI is most efficient at detecting small, or even punctate (point sized), cavernous angiomas.[10] Even though a spin-echo MRI may have detected a lesion, it’s always prudent to ensure that there are not additional, smaller lesions which might become a problem later in life.

Angiography

This is the most accurate test and the best way to diagnose an AVM and reveal the location of the feeding arteries and draining veins. A thin tube is inserted into an artery in the groin. This thin tube is threaded up toward the brain to the blood vessels. Dye is injected into the blood vessels of the brain and pictures are taken. An AVM will show up as a tangle of blood vessels. Physicians are able to see the exact location and size of the AVM.
