- BACKGROUND: Patients with complex shunt-related problems and varying diagnoses of cerebrospinal fluid (CSF) disturbance can present with headache and clinical symptoms that may be difficult to relate to underdrainage or overdrainage. Telemetric intracranial pressure (ICP) monitoring may assist in evaluating individual patients and assessing shunt function and adjustment. We report a case series of patients receiving a Miethke M.scio sensor.METHODS: Between June 2016 and August 2021, 14 patients older than 18 years with different diagnoses underwent ventriculoperitoneal shunt surgery and received a Miethke M.scio sensor.RESULTS: Patients had idiopathic intracranial hyper-tension (n = 3), obstructive hydrocephalus caused by tumors (n = 4), and malformations (n = 5). Headaches (71%) and visual impairment (50%) were the most common symptoms before surgery and 65% of the symptoms were improved after surgery. In total, 25 measurements were made and 11 of these led to changes in the shunt settings. Postoperative measurements were taken in 8 patients and the most common indication of ICP measurement was headache and/or control of the shunt settings.CONCLUSIONS: The Miethke M.scio is a safe and valuable device to use in shunt-treated patients, in particular those expected to need assessment of ICP monitoring postoperatively. Repeated ICP measurements can also assist in personalized adjustment of the shunt setting to optimize CSF flow in this diverse patient group. Future studies should include a standardized protocol with ICP measurements correlated to the symptoms and cause of CSF disturbances to provide better understanding of the dynamics of the ICP in each patient.

- BACKGROUND: Intracranial arachnoid cysts (ACs) are generally benign fluid-filled cysts with a prevalence of 0.5%-2.7%. They can be treated through craniotomy with cyst removal, endoscopic fenestration, or cystoperitoneal or ventriculoperitoneal shunting. However, the outcome of these treatments has not been completely satisfactory. Cystoventricular shunting was described as an alternative method for the treatment of intracranial ACs in children in 2003. In the present report, we have described the outcomes of cystoventricular shunting in adults with symptomatic intracranial ACs.METHODS: A total of 24 patients with symptomatic ACs underwent cystoventricular drainage from 2012 to 2019. The most common symptom preoperatively was headache, followed by dysphasia, motor weakness, memory loss, seizures, and balance disturbances. After radiological evaluation, a ventricular catheter was placed in the AC and another in one of the lateral ventricles and connected extracranially after subgaleal tunneling using a straight metal connector.RESULTS: At 3-6 months of postoperative follow-up, 21% of patients were asymptomatic and 42% showed improvement in clinical symptoms. No patient had experienced impairment or progression of symptoms postoperatively. Three patients had required revision of the catheters and one patient had developed a postoperative superficial skin infection without signs of deeper infection.CONCLUSIONS: Cystoventricular drainage seems to be an effective, reliable, and safe procedure to treat intracranial ACs when fenestration to the basal cisterns is not possible.

- INTRODUCTION: There are no reliable noninvasive methods of monitoring ICP. Most assessments are made by indirect measures and are difficult to follow over time. Invasive studies can be used but up until now have required in-hospital transcutaneous measurements. Accurate ICP recordings over longer periods of time can be very valuable in timing different surgical procedures in syndromal cases. This case shows that telemetric ICP monitoring can be used for long-term follow-up in patients that may need repeated surgeries related to their craniosynostosis condition.CASE REPORT: In this report, the telemetric ICP probe (Raumedic Neurovent-P-tel) was implanted before surgery and was used for repeated "noninvasive" ICP recordings pre- and postoperatively in a patient with craniosynostosis. The patient was an eight-year-old girl with pansynostosis with only the right lambdoid suture open. A telemetric ICP probe was implanted the day before cranial vault remodeling and the ICP was monitored pre- and postoperatively. The ICP was above 15 mmHg 72.2 % of the monitoring time before surgery, and the amplitude of the curve was greater than normal suggesting impaired compliance. Direct postoperative ICP was normal, and the amplitude was lower. The ICP was then monitored both in out-patient clinic and in four longer hospital stays. Both the values and the curves were analyzed, and the time with ICP above 15 mmHg decreased over time, and the waveform amplitude of the curves improved.CONCLUSION: This "noninvasive" way of recording ICP is a feasible and helpful tool in decision-making and intervening in patients with craniosynostosis.
