[Venous factor in surgical management of skull base meningiomas].

Skull base venous system is a variable anatomical formation in both health and pathology. Damage to venous structures during surgical treatment of craniobasal meningiomas can lead to formidable postoperative complications, such as hemorrhagic infarctions, cerebral edema and persistent neurological deficit. Despite the improvement of microsurgical techniques, methods of morphological and functional angiography, as well as modeling the mechanisms of compensation for venous hemodynamic disorders, the problem of preventing postoperative venous complications remains relevant.

Objective: To analyze available literature data on the role of venous system in surgery for skull base meningiomas and prevention of venous outflow disorders.

Material and methods: The PRISMA algorithm was used to search for publications on venous complications, venous outflow compensation and prevention of vein damage in skull base meningiomas. The PubMed and Google Scholar databases were reviewed.

Results: Thirty-six manuscripts were assessed. Statistics of venous complications in neurosurgery, venous system reorganization in craniobasal meningiomas, modern methods of X-ray diagnosis and minimization of venous complications during tumor resection are described.

Conclusion: Peculiarities of venous hemodynamics in skull base meningiomas are important in planning surgical treatment, as evidenced by many studies in recent years. Improvement of microsurgical techniques and highly informative methods of X-ray diagnosis reduce the likelihood of venous complications in neurosurgery. However, persistent risk of vein damage during resection of craniobasal meningiomas necessitates further improvement of diagnostic and treatment algorithms.
