| Popis: | Background Outcomes of surgical treated patients with giant retrocerebellar arachnoid cysts with the available typically preferred techniques frequently are unsatisfactory. Objectives We hypothesized that a pressure gradient may exist between the cyst and the ventricular system that may be responsible for the posterior fossa–related symptoms and headaches, and, if so, that connecting both cavities by means of a shunt catheter (i.e., cystoventricular stent), the pressure differences would equilibrate and the symptoms resolve. To prove our hypothesis, we decided to simultaneously monitor the intracyst pressure and the intraventricular pressure. Methods This was a retrospective chart review analysis of 5 consecutive patients with giant retrocerebellar arachnoid cysts treated between 2014 and 2016. Results Four patients underwent 3 days of continuous intracranial pressure monitoring, and 1 patient was monitored in the surgical suit. Cyst and ventricular pressures tended to be within normal accepted values in all patients, and a pressure gradient was noticed only in the 2 patients with previous cyst surgeries. All patients were treated with a cystoventricular stent, and overall, had long-term sustained good outcomes, with resolution of symptoms in 3 and significant improvement in 2. Conclusions Patients with symptomatic large retrocerebellar arachnoid cysts do not seem to have increased intracranial pressure, and regardless of the presence or absence of a pressure gradient between the cyst and the ventricles, a cystoventricular stent seems to be effective and the best first surgical option to offer. |
