[Neurovascular compression syndrome in the upper thoracic aperture region: diagnosis and surgical treatment].

Unlabelled: Neurovascular compression syndrome (NVCS) in the region of the upper thoracic aperture (UTA) occurs due to significant compression of the vascular-nervous bundle (VNB) in narrow anatomical spaces, which are represented by an interscalene space, costoclavicular space and area under the pectoralis minor tendon. Based on the data of traditional clinical and instrumental research methods, it is not always possible to accurately determine the nature and level of damage to the vascular-nervous bundle (VNB), that is often caused by variability of anatomical organization of the peripheral nervous system.

Objective: To identify and describe the specific clinical features of NVCS in the region of UTA and propose an informative instrumental method of diagnosis for development of the optimal surgical treatment algorithm.

New Classification of the Degree of Cerebrovascular Insufficiency in Patients with Moyamoya Disease Measured According to ASL-MRI Perfusion.

Introduction: We aimed to classify different degrees of cerebrovascular insufficiency (CVI) in patients with moyamoya disease (MMD) by measuring cerebral blood flow (CBF) and distinguishing arterial transit artifacts (ATAs) on arterial spin labeling (ASL) magnetic resonance imaging (MRI).

Methods: The study included 121 images of patients with MMD who underwent ASL-MRI before and after surgical treatment (242 hemispheres). On ASL-CBF maps, regions of interest (ROIs) were manually drawn in each hemisphere in seven zones.

Cerebral Ischemic Complications of Surgical Treatment in Patients with Moyamoya Disease.

Objective: We aimed to identify unfavorable prognostic factors for the development of cerebral ischemic complications of surgical treatment in patients with moyamoya disease.

Methods: We analyzed 80 patients with moyamoya disease, who underwent 134 surgical revascularizations. Persistent complications (ischemic strokes) developed in seven cases (5.

Does Whole Brain Radiomics on Multimodal Neuroimaging Make Sense in Neuro-Oncology? A Proof of Concept Study.

Employing a whole-brain (WB) mask as a region of interest for extracting radiomic features is a feasible, albeit less common, approach in neuro-oncology research. This study aims to evaluate the relationship between WB radiomic features, derived from various neuroimaging modalities in patients with gliomas, and some key baseline characteristics of patients and tumors such as sex, histological tumor type, WHO Grade (2021), IDH1 mutation status, necrosis lesions, contrast enhancement, T/N peak value and metabolic tumor volume. Forty-one patients (average age 50 ± 15 years, 21 females and 20 males) with supratentorial glial tumors were enrolled in this study.

Neurosurgical viewfinder - a simple device for navigation of superficial intracranial lesions: prospective, controlled study.

Incorrect position of craniotomy can seriously complicate the course of operation. Frameless navigation stations (FNS) allow accurate craniotomy marking. However, FNS are cumbersome, time consuming, and not accessible to all neurosurgical centers.
