Bleeding risk of small intracranial aneurysms in a population treated in a reference center

Abstract

Large multicenter studies on unruptured aneurysms have shown a relatively low rupture rate for smaller aneurysms compared with larger ones 1,2 . Nevertheless, controversy on the subject still persists, based on the fact that a high percentage of patients admitted to reference centers with subarachnoidal hemorrhage (SAH) present with aneurysms smaller

Abordagem endovascular de Aneurismas Intracranianos Gigantes tratados com stents de fluxo e embolização com micromolas: artigo de revisão

“…14,18,19 Os aneurismas da artéria cerebral anterior e os pacientes com hipertensão arterial apresentaram maior risco de hemorragia, sendo que quanto maior o diâmetro no momento do diagnóstico, maior é a chance de ruptura. 20 A classificação dos aneurismas intracranianos varia de acordo com as análises da morfologia, do tamanho, da etiologia e da localização. Aneurismas saculares são protrusões arredondadas focais parietais, originados, geralmente, na parede lateral da artéria.…”

Epidemiological characteristics and causes of death after Aneurysmal Subarachnoid Hemorrhage – SAH

“…The morphological characteristics, size and location of the aneurysms, on the other hand, were not associated with poor outcomes when analyzed. Although the literature is abundant and with different results, [30][31][32][33] these characteristics were also not predictors of death. Neurological complications after SAH are a reflection of causes underlying the clinical degree at admission and neuroimaging.…”

Intracranial aneurysm diameter and risk of rupture

“…Felipe Padovani TRIVELATO 1 , Alexandre Cordeiro ULHÔA 1 , Daniel Giansante ABUD 2 , Marco Túlio Salles REZENDE 1 Dear Editors, We read with great interest the article, "Bleeding risk of small intracranial aneurysms in a population treated in a reference center" by Lepski et al 1 , in which the authors proposed a new method to address the relationship between aneurysm size and the prevalence of rupture.…”

“…Lepski et al 1 retrospectively studied a population of 290 patients harboring both ruptured and non-ruptured newlydiagnosed aneurysms. The mean largest diameter for the ruptured versus unruptured groups was 13.3 mm ± 1.7 mm versus 22.2 ± 2.2 mm.…”
