Intracranial Aneurysm

Hjärnaneurysm

Svensk definition

Medfödd eller förvärvad utbuktning i kärlväggen av blodkärl i hjärnan. Säck- eller bärformade åderbråck är den vanligaste varianten och bildas oftast vid artärförgreningar nära hjärnbasen. Bristning leder till subaraknoidalblödning eller intrakraniella blödningar. Jätteaneurysm (>2,5 cm i tvärsnitt) kan trycka ihop intilliggande vävnadsstrukturer, inkl. okulomotoriska nerven (tredje hjärnnerven).

Engelsk definition

Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE.
