The experience of surgical treatment of arachnoid cysts of the brain in the conditions of the neurosurgical department by Moscow Regional Research and Clinical Institute

Leonov Pavel Sergeevich, Kiselev Anatoliy Mikhailovich

Arachnoid cysts are a common pathology, including about 1% of all intracranial volume tumors. Nowadays, tactic of surgical treatment is not clearly defined. More and more authors prefer endoscopic methods of treatment of arachnoid cysts, while microsurgical and shunting operations rightly go to the background. Also, to date indication for surgery has not yet taken an explicit: what is the criterion of an "aggressive" cyst and in which cases asymptomatic cysts require surgical treatment. This article reflects the analysis of clinical and x-ray results of surgical treatment of arachnoid cysts of the brain on 20 adult patients operated on in the MONIKI of M. F. Vladimirsky from 2008 to 2017. In the group of patients, priority was given to endoscopic treatment of this pathology. Following the intervention, regression of clinical symptoms was noted in 16 patients. No positive impact has been achieved in 4 patients after the first surgery: they needed additional surgery or a change in tactics. Endoscopic fenestration is a safe, effective and miniinvasion method at the first stage of treatment of patients with congenital symptomatic arachnoid cysts.
