Abstract
|
|
|
|
Intracranial ruptured dissecting aneurysms can have fatal outcomes. Among them, posterior cerebral artery dissecting aneurysm with hemorrhage is uncommon but usually fatal due to its deep location and proximity to surrounding critical structures. Most previously published reports on this type of aneurysm have concluded that the neurologic outcome can be improved with the use of certain surgical or endovascular approaches. However, in severe cases with a poor initial clinical status, patient improvement should not be expected. We report two cases of P2-3 segment ruptured dissecting aneurysms that were treated by external ventricular drainage for control of increased intracranial pressure followed by one-stage endovascular treatment for the aneurysm.
