Sub arachnoid hemorrhage consecutive to intracranial aneurysm rupture is a devastating disease. Predictors of intracranial aneurysm rupture are limited and focus mainly on size and location. Platelet activation may have a deleterious role on aneurysm rupture. The assumption is that patients with ruptured intracranial aneurysm will present a higher rate of platelet activation compared to patients with non ruptured aneurysms.

Condition Intracranial Aneurysms, Ruptured Aneurysm
Treatment Collection of blood sample in aneurysm
