Abstract

Background: Despite BMI Cerebrospinal Fluid (CSF) Shunting System has been on the market for decades, no studies have been carried out. This retrospective study examined its clinical performance and safety, and attempted to discern risk factors. Methods: Medical records from 232 patients with External Ventricular Drainage (EVD) placement and 35 patients with Ventriculoperitoneal (VP) shunt placement were reviewed for 1 year and 2 years postoperatively, respectively. Results: The incidence of device malfunction was 22.9% for VP shunt in 2 years and 25.4% for EVD in 1 year. The most common cause of device malfunction was over drainage for VP shunt; and distal displacement and infection for EVD. The incidence of complications was 2.9% in the VP shunt group and 27.6% in the EVD group, while that of device-related infections were 0.0% and 7.3%, respectively. No one in the VP shunt died in 2 years postoperatively, while 2 patients (0.9%) in the EVD group died in 1 year postoperatively. No factors were found to influence the VP shunt survival; while age, catheter diameter, type of hydrocephalus, and Glasgow Coma Scale (GCS) score before surgery were found to have significant impact on EVD function. Conclusion: Compared to other similar device, BMI EVD showed comparable clinical performance and VP shunt showed superior clinical performance. Both devices were safe, with limited devicerelated infections reported. Our study sheds some light on the long-term outcome of BMI CSF Shunting System. Further study on a larger population is warranted to verify the predictors of device survival we identified in this analysis.
