Arterial aneurysms of cerebral vessels

Aneurysm - a local dilatation of the artery lumen as a result of changes or damage to its walls. Most often, brain aneurysms are a disease of the arterial tees of the Willis polygon.

Symptoms of the arterial aneurysms of the brain

• Dogemorrhagic period (asymptomatic or asymptomatic course, less often tumorous-like course with large aneurysm size).
• Hemorrhagic period (clinic of hemorrhagic stroke mainly as a subarachnoid hemorrhage).

Forms

• Bifurcation-hemodynamic aneurysms (so-called congenital):
  • Bifurcation-hemodynamic aneurysms in systemic arterial hypertension;
  • Bifurcation-hemodynamic aneurysms in regional hemodynamic disorders (fibro-muscular dysplasia, moya-moya disease, anomalies in the development of the arterial circle of the large brain);
  • Bifurcation-hemodynamic aneurysms in some hereditary diseases (Marfan, Ehlers-Danlo, Grenblad-Strandberg, Friedreich, Bloom, Pompe disease).
• Degenerative-necrotic aneurysms (radiation, atherosclerotic).
• Traumatic (with traumatic brain injury).
• Inflammatory (as a result of vasculitis, embolic bacterial or mycotic).
• Oncogenic.
• Dysambriogeneticheskie.
• Iatrogenic.

Treatment of the arterial aneurysms of the brain

• Open (transcranial) interventions.
• Endovascular interventions using:
  • balloon-catheters;
  • stents;
  • spirals (coils).
