Geometric and Hemodynamic Analysis of the Risk of Rupture of Intracranial Aneurysms

Intracranial aneurysms are dilaNons of the walls of the cerebral arteries, their rupture causes subarachnoid haemorrhage, an enNty of high mortality and sequelae among survivors. This series of studies analyze mulNple intracranial aneurysms, anterior communicaNng artery aneurysms and rebleeding acer...

Sumario:Intracranial aneurysms are dilaNons of the walls of the cerebral arteries, their rupture causes subarachnoid haemorrhage, an enNty of high mortality and sequelae among survivors. This series of studies analyze mulNple intracranial aneurysms, anterior communicaNng artery aneurysms and rebleeding acer placement of an external ventricular drainage using computaNonal fluid dynamics methods from imaging studies of real paNents. Treatment of a proximal aneurysm, absence of asymmetry of A1 and decreased A1/A2 angles in asynchrony of A1 artery increases the theorieNcal risk of rupture. External ventricular drainage increases the wall displacement in low shear areas of the aneurysm favoring rebleeding of the aneurysm.
