Aneurysm

aneurysmsaneurismruptured aneurysm
Aneurysms in the posterior circulation (basilar artery, vertebral arteries and posterior communicating artery) have a higher risk of rupture.
The brain, including cerebral aneurysms, berry aneurysms, and Charcot–Bouchard aneurysms.

Subarachnoid hemorrhage

subarachnoid haemorrhagesubarachnoidsubarachnoid hemorrhage, traumatic
This is called a subarachnoid hemorrhage.
SAH may occur as a result of a head injury or spontaneously, usually from a ruptured cerebral aneurysm.

Intracerebral hemorrhage

cerebral hemorrhagebrain hemorrhagecerebral haemorrhage
A ruptured microaneurysm may cause an intracerebral hemorrhage, presenting as a focal neurological deficit.
Causes include brain trauma, aneurysms, arteriovenous malformations, and brain tumors.

Posterior communicating artery

posterior communicating arteriesposterior communicating
Aneurysms in the posterior circulation (basilar artery, vertebral arteries and posterior communicating artery) have a higher risk of rupture.
Aneurysms of the posterior communicating artery are the third most common circle of Willis aneurysm (the most common are anterior communicating artery aneurysms) and can lead to oculomotor nerve palsy.

Intracranial hemorrhage

Charcot–Bouchard aneurysms are a common cause of intracranial hemorrhage.
Besides from head injury, it may occur spontaneously, usually from a ruptured cerebral aneurysm.

Endovascular coiling

endovascular coilsendovascularendovascular coil
Currently there are two treatment options for securing intracranial aneurysms: surgical clipping or endovascular coiling.
Endovascular coiling, or endovascular embolization, is an endovascular treatment for intracranial aneurysms and bleeding throughout the body.

Xanthochromia

Once an LP is performed, the CSF is evaluated for RBC count, and presence or absence of xanthochromia.
The most common cause for bleeding into the subarachnoid space is a subarachnoid hemorrhage from a ruptured cerebral aneurysm.

International Subarachnoid Aneurysm Trial

In particular, the large randomised control trial International Subarachnoid Aneurysm Trial appears to indicate a higher rate of recurrence when intracerebral aneurysms are treated using endovascular coiling.
The International Subarachnoid Aneurysm Trial (ISAT) was a large multicentre, prospective randomised clinical medical trial, comparing the safety and efficacy of endovascular coil treatment and surgical clipping for the treatment of brain aneurysms.

Intracranial aneurysm, also known as brain aneurysm, is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel. Microaneurysms, also known as Charcot-Bouchard aneurysms, typically occur in small blood vessels (less than 300 micrometre diameter), most often the lenticulostriate vessels of the basal ganglia, and are associated with chronic hypertension.
