Abstract
Spontaneous subarachnoid hemorrhage (SAH) is usually caused by a ruptured intracranial
aneurysm, most frequently the aneurysm of internal carotid artery, anterior communicating
artery or middle cerebral artery. Significant prognostic factors include the localization
and size of the aneurysm. Intracranial aneurysms can be divided according to their
anatomical location to aneuryms of anterior and posterior brain circulation (i.e. aneurysm
of the carotid and vertebrobasilar circulation). Due to the localization and closeness to the
brain stem, patients with aneurysms of the posterior circulation have a poor outcome. The
most common clinical symptom of SAH is sudden and severe headache, reduced level of
consciousness, signs of increased intracranial pressure and nuchal rigidity. Diagnostic methods
of choice are computerized tomography scans and cerebral angiography which represent
the gold standard. The treatment of SAH can be surgical or endovascular and the
choice depends on patient status, anatomical localization of the aneurysm and surgeon
competencies. The surgical approach depends on the anatomical localization of the aneurysm.
