What is Intracranial Aneurysm?

An Intracranial Aneurysm is a cerebrovascular disorder in which a balloon-like bulge occurs in a weakened artery.  When the bulging stretches too far, an aneurysm may burst, causing Subarachnoid Hemorrhage (SAH).  An aneurysm that bleeds into the brain can lead to stroke and death.  5-6% of human beings harbour an unruptured intracranial aneurysm. Each year in the United States, more than 30,000 people suffer from a ruptured intracranial aneurysm.*  Incidence of aneurysmal SAH varies widely depending on geographic location, with the highest reported rates in Finland and Japan. Overall, the incidence has been estimated at 10.5 per 100,000 individuals.

Treatments for Intracranial Aneurysm

Surgical Clipping Craniotomy – The neck of the aneurysm is pinched off to eliminate chances of SAH.  However, the procedure requires long surgical and recovery time.  The surgical process also involves craniotomy, which can cause massive brain damage if not performed well.

NeuroInterventional Embolization – Minimally invasive technique, in which platinum coils are deployed into the aneurysm, leading to the formation of thrombosis inside the aneurysm, which shuts off blood flow to the aneurysm, preventing it from bursting.
