title: [Pathology of cerebral artery aneurysms in the light of their surgical treatment].
abstract: Surgical treatment of cerebral aneurysms had a significant influence on the pattern of the course, manifestations, and outcomes of the disease. Variants of complications of surgical interventions occurring in operations made early and late after rupture of the aneurysms in open and intravascular accesses are analysed, as well as morphological aspects of the cerebral vasospasm. A previously unknown mechanism of growth and shape formation of aneurysms associated with separation of the intima of the carrying vessel is described. The current concepts on the mechanisms of aneurysm rupture are analysed. The importance of exfoliating hematomas which in some cases precede the rupture is emphasized. The capacity of aneurysm wall for regeneration is limited. Healing of the rupture occurs predominantly at the expense of hematoma organization around the aneurysm sac. The "defective" regeneration is the cause of frequent recurrent ruptures and limit the use of aneurysm ballooning in the acute period of their rupture.
