Leonov Pavel Sergeevich, Kiselev Anatoliy Mikhailovich

Arachnoid cysts (AC) are congenital diseases of the liquorices system obtained about 1% of all intracranial tumors. As yet, there are no common tactics of surgical treatment. More and more authors prefer endoscopic methods of treatment A), while, microsurgical and bypass surgery resonably goes to the background. However, there is still a need to define a clear indications for surgery. Article reflects clinical analyses and X-ray results of surgical treatment A) of brain on 36 adults patients which were operated in in the MONIKI named of M. F. Vladimirsky since 2008 up to 2018. We have applied main surgical methods of treatment: open cutting, endoscopic fenestration and the bypass system installation. Priority was given to endoscopic method in view of its low injuries and high radical effect. After the surgical operation 34 patients were noted regression of pathological status. No positive impact has been achieved on 2 patients after the first surgery: they needed an additional surgery or change in tactics of treatment. Endoscopic fenestration is a safe, effective and low-invasive method at the first stage of treatment of patients with congenital symptomatics.
