BACKGROUND AND PURPOSE: Most arachnoid cysts (ACs) are asymptomatic, but some of them cause mass effect, mainly in adults. Surgery of ACs is controversial, especially regarding the choice of the best method of treatment. The authors present short- and long-term outcome of endoscopic surgery of ACs.
MATERIALS AND METHODS: There were 19 adults with symptomatic ACs treated surgically in the last 6 years. 16 cysts were located supratentorially, and 3 infratentorially. Cystocisternostomy was carried out in 7 patients, cystocisternostomy with catheter implantation was performed in 5 patients, cystoventriculostomy in 3 patients, and cystoventriculostomy with catheter implantation was carried out in 2 patients. In one case additional endoscopy combined with shunt was necessary, and in another one endoscopy converted to microsurgery. Outcome was assessed by means of neurological examination and computed tomography (CT).
RESULTS: During the short-term follow-up, 11 (57.9%) cases improved neurologically, and in 6 (33.0%) ACs were significantly smaller in CT. During the long-term follow-up, 14 (73.7%) patients improved significantly, and the size of ACs was reduced in 16 (84.2%). In two cases subdural haematoma was observed.
CONCLUSIONS: Outcome after endoscopic surgery of ACs in adults is good, and the complication rate is low. Endoscopy should be recommended as the treatment of choice in patients suffering from ACs.
