The paper gives the results of a study conducted in 3 groups of neurosurgical patients in the analysis of autoptic material over 15 years in order to detect pulmonary arterial thromboembolism (PATE) as a cause of postoperative death in neurosurgical patients. In the latter, the incidence of PATE was ascertained to be 5.4%, as evidenced by autopsy and the distribution of the onset of a fatal outcome was biphasic. The informative value of determination of the blood level of fibrin D-dimer was analyzed in neurosurgical patients as a screening method for diagnosing prethrombosis. The method has shown to be of high informative value (about 90% sensitivity) and may be used in clinical practice. The effectiveness and safety of the combined procedure of preventing venous thromboembolic events (mechanical method with a subsequent switching over to pharmacological methods on days 3) were evaluated. The method has proven to be effective and safe.

Lumbar spinal surgery relies on palpation of anatomical landmarks and X-ray imaging confirmation to identify the correct spinal level, therefore exposing patients and staff to radiation, and increasing intraoperative time and cost. Ultrasound (US) assistance is being used to visualise spinal anatomy by many specialities, such as neurology and anaesthetics, and can be used intraoperatively in selected spinal surgery cases. However, its potential use to check spinal levels prior to surgery remains understudied.

Patients with cerebral venous thrombosis (CVT) may experience poor response to anticoagulant therapy and delayed surgical treatment may lead to clinical deterioration. However, the factors contributing to clinical deterioration remain poorly understood. Patients with CVT from three centers between January 2017 and October 2023 were included and grouped as the development cohort and validation cohort.

To describe the distribution of jugular bulb position and pneumatization of posterior lip of internal auditory meatus (IAM) in patients with vestibular schwannoma (VS). This retrospective study included 43 patients who had a thin slice (< 2 mm) CT temporal bone for preoperative planning of retrosigmoid approach for excision of VS between March 2011 and March 2021. On computed tomography (CT), high riding jugular bulb was defined by its relationship to IAM and correlated with type of jugular bulb according to Manjila et al.

Currently, limited evidence exists on the impact of serum sodium variability in patients with aneurysmal subarachnoid hemorrhage (SAH) who underwent surgical clipping. We aimed to perform a detailed examination of the relationship between sodium variability and mortality in these patients. We conducted a cohort study including adult patients with aneurysmal SAH who underwent surgical clipping at a university hospital.
