Subarachnoid hemorrhage is bleeding in the area between the brain and the thin tissues that cover the brain. Subarachnoid hemorrhage is one of the most devastating types of hemorrhage in the brain.
Subarachnoid hemorrhage due to rupture of a cerebral aneurysm is most common in persons ages 20 to 60. It is slightly more common in women than men. The main symptom is a severe headache that starts suddenly and is often worse near the back of the head.
The aneurysm needs to be occluded as soon as possible inorder to prevent rebleed.
The incidence of re-bleed following SAH is 20% in the 1st 2 weeks
Coiling is a very good alternative to clipping, which can be done even in the presence of vasospasm.
Recent advances in the endovascular therapy in the past decade made this a minimal invasive procedure a feasible and effective method in the treatment of aneurysms.
