in·tra·cra·ni·al an·eu·rysm

any aneurysm located within the cranium.

intracranial aneurysm

localized dilation of any of the cerebral arteries. Characteristics of the condition include sudden severe headache, stiff neck, photophobia, nausea, vomiting, and sometimes loss of consciousness. Rupture of an intracranial aneurysm produces a mortality rate approaching 50%, and survivors face a high risk of recurrence. Some forms of intracranial aneurysm may be treated surgically. Kinds of intracranial aneurysms include berry aneurysm, fusiform aneurysm, and mycotic aneurysm.

Most patients assessed using the Hunt and Hess Scale (Hunt & Hess, 1968) were classified into groups I-IlL According to world neurosurgical standards, group "0" patients are patients with a diagnosed intracranial aneurysm that has not yet ruptured; groups I-III patients are patients in a relatively good general condition, with little surgical risk and good treatment results; and groups IV-V patients are in a very bad condition, with high surgical risk and unsatisfactory treatment results (Table 1).

Using CTA source images and orthogonal multiplanar reformations that are produced at the CT console in 5 to 10 minutes, the radiologist may confirm the presence and location of an underlying intracranial aneurysm as well as provide aneurysm morphology information (Figure 5).
Intraoperative hypothermia doesn't improve neurologic outcomes in patients undergoing intracranial aneurysm repair--a finding with broad ramifications, given that cooling is now used in over half of aneurysm surgeries because many believe it's neuroprotective, said Michael M.
