The new algorithm for stratification of the risk of venous thromboembolic events in elective neurosurgery and its prognostic significance.

Unlabelled: Early identification of risk groups is essential for effective and target prevention of venous thromboembolic events (VTE) in all areas of surgery. For this purpose, the authors has developed and put into practice an algorithm distinguishing the groups of low, moderate and high risk of VTE among neurosurgical patients.

Objective: To assess predictive value of the developed algorithm for elective neurosurgical interventions.

[Surgical treatment of cervical paragangliomas].

Aim: To present own experience in surgical treatment of cervical paragangliomas.

Material And Methods: 9 patients with cervical paragangliomas were enrolled. Endovascular embolization of supplying vessels followed by maximally radical surgery and subsequent carotid arteries repair involved into tumoral process reduces the risk of complications.

[The use of high-flow extracranial-intracranial artery bypass in pathology of the cerebral and brachiocephalic arteries: technical features and surgical outcomes].

Background: Poor outcomes of surgical treatment for complex cerebral aneurysms due to the development of cerebral ischemia were the cause to use cerebral revascularization surgery for this pathology.

Objective: the study objective was to master a high-flow extracranial-intracranial (EC-IC) artery bypass technique and evaluate its application in surgical treatment of complex and giant cerebral aneurysms as well as complex lesions of the brachiocephalic arteries.

Material And Methods: Fifty two patients underwent high-flow IC-EC bypass surgery; of these, 34 patients had complex cerebral aneurysms, and 18 patients had complex stenotic occlusive lesions of the brachiocephalic arteries.

[Surgical treatment of distal extracranial internal carotid artery aneurysms associated with pathological artery kinking].

Extracranial internal carotid artery (ICA) aneurysms located at the entrance of the skull are a rare pathology. Surgical treatment is indicated for this pathology because of the risk of arterio-arterial embolism and the development of cerebrovascular disease. The domestic and international literature reports single cases or small group cases of successful surgical treatment of patients with distal internal carotid artery aneurysms associated with pathological kinking of the artery.
