[Analysis of intracranial saccular aneurysm wall: neuroimaging and histopathological correlates].

Background: Contrast enhancement of intracranial aneurysm wall during MRI with targeted visualization of vascular wall correlates with previous aneurysm rupture and, according to some data, may be a predictor of further rupture of unruptured aneurysms.

Objective: To analyze possible causes of aneurysm contrast enhancement considering morphological data of aneurysm walls.

Material And Methods: The study included 44 patients with intracranial aneurysms who underwent preoperative MRI between November 2020 and September 2022.

[Pathological tortuosity of intracranial arteries (pure arterial malformation) - diagnosis and management tactics].

Background: Tortuosity of intracranial arteries is rare and usually mistaken for arteriovenous malformations. In the world literature, the term «pure arterial malformations» is used to refer to this disease.

Objective: To summarize the experience of the Burdenko Neurosurgery Center on diagnosis of intracranial artery tortuosity, management and treatment of these patients, as well as to review appropriate literature data.

Magnetic resonance imaging of saccular intracranial aneurysm wall.

Background: Hemorrhage from intracranial aneurysms is associated with high risk of adverse outcomes. In this regard, surgical treatment of unruptured asymptomatic aneurysms has been actively developed in recent decades. One of the objectives is searching for predictors of aneurysm rupture to clarify the indications for surgery.

Giant Middle Cerebral Artery Aneurysms: A 55-Patient Series.

Background: The treatment of middle cerebral artery (MCA) giant aneurysms (GAs) represents a challenging task.

Methods: The data for 55 patients treated for MCA GA (≥25 mm) at the N.N.

[Surgical treatment of patients with cerebral aneurysms in the acute stage of rupture: dynamics of results during 2006-2018].

Unlabelled: Treatment of cerebral aneurysms in the acute stage of subarachnoid hemorrhage (SRH) especially on the background of cerebral vasospasm continues to be a difficult task.

Objective: Assessment of dynamics of the surgical treatment results of patients with cerebral aneurysms in acute period of SRH.

Material And Methods: A comparative analysis of the results of patients' surgical treatment in NMRCN Burdenko about aneurysm in 1-21 days after hemorrhage was made.
