Peripheral cerebral aneurysms: clinical picture and diagnostics

The article is devoted to the clinical manifestations and diagnosis of peripheral cerebral aneurysms. The clinical course of this disease was analyzed in 139 patients depending on topographic and anatomical features (106 patients with hemorrhagic stroke, 33 without a history of aneurysm rupture). The study included patients with peripheral aneurysms of the anterior cerebral, middle cerebral arteries, posterior cerebral, posterior inferior cerebellar arteries. A high incidence of seizures was noted in case of rupture of distal aneurysms (up to 10%). Quite typical for hemorrhage from peripheral aneurysms was the formation of an intracerebral hematoma (43.1%). A comparison of diagnostic methods for detection of this vascular pathology was performed: cerebral angiography (informative in 93.3%), СТ angiography (CTA) (90.9%) and magnetic resonance imaging in the vascular mode (12.2%). CTA is a highly effective method for diagnosing peripheral cerebral aneurysms and in most cases does not require additional invasive angiographic examination.
