Brain Aneurysm, is a cerebrovascular disorder in which weakness in the wall of a cerebral artery causes a localized
dilation or ballooning of the blood vessel.
A small aneurysm will produce few, if any, symptoms. Before a larger aneurysm ruptures, the individual may experience
such symptoms as a sudden and unusually severe headache, nausea, vision impairment, vomiting, and loss of consciousness,
or no symptoms at all. If aneurysm ruptures, blood leaks into the space around the brain. A ruptured aneurysm
quickly becomes life-threatening and requires prompt medical treatment. Diagnosis is done by performing CT angiography
or DSA to confirm the exact size and site of aneurysm. Currently there are two treatment options for securing
intracranial aneurysms: surgical clipping or endovascular coiling. Surgical clipping involves clipping the base
of the aneurysm with a specially-designed clip and thus occluding the ruptured aneurysm and prevent rebleeding
into the brain. Endovascular coiling refers to the insertion of platinum coils into the aneurysm.
