[Frequency of Ponticulus posticus and Ponticulus lateralis in patients admitted to hospital with traumatic brain injur].

Objective: To determine the frequency of and among patients admitted to a24-hour emergency hospital.

Material And Methods: The study included 2887 patients with a traumatic history who were admitted to the hospital for emergency reasons. This principle of sampling allowed us to exclude a high concentration of studies of patients with chronic neurological diseases, the cause of which could be symptomatic Kimmerle's anomaly (KA).

[Surgical revascularization of the brain in patients with acute ischaemic stroke].

Aim: The study was aimed at developing a surgical policy for patients presenting with acute ischaemic stroke induced by lesions of the intra- and extracranial arteries.

Patients And Methods: The patients were enrolled into the study resulting from the current practice of the Department of Emergency Neurosurgery of the Research Institute of Emergency Medicine named after N.V.

Minimally Invasive Surgical Treatment for Vertebral Artery Compression in a Patient with One-Sided Ponticulus Posticus and Ponticulus Lateralis.

Background: Kimmerle anomaly is characterized by ossification of the posterior atlanto-occipital membrane with formation of a complete or incomplete bony ridge in the area of the groove for the vertebral artery (VA) (ponticulus posticus [PP]). In some cases, the bony ridge may also be formed at the level of the VA emerging from the transverse process of the С1 vertebra (ponticulus lateralis [PL]). Simultaneous 1-sided formation of PL and PP is very rare.

Minimally invasive surgical treatment for Kimmerle anomaly.

Introduction: Kimmerle anomaly is the bony ridge between the lateral mass of atlas and its posterior arch or transverse process. This bony tunnel may include the V3 segment of the vertebral artery, vertebral vein, posterior branch of the C1 spinal nerve, and the sympathetic nerves, which results in the clinical symptoms of this disease. Reports on the surgical treatment of Kimmerle anomaly are rare.

[Assessing efficacy of carotid endarterectomy by means of intraoperative flowmetry].

Aim: The study was aimed at determining volumetric blood flow velocity (VBFV) through the internal carotid artery (ICA) and assessing functional outcomes of treatment of patients, taking into consideration the dynamics of VBFV before and after the operation.

Patients And Methods: The study comprised a total of 53 patients subjected to examination of VBFV through the ICA before and after carotid endarterectomy (CEA) assessed by means of flowmetry. Neurological deficit was evaluated by means of the NIHS Scale (the M NIHSS prior to operation equalling 2.
