OUTCOMES OF VENTRICULOPERITONEAL SHUNT SURGERY USING ADJUSTABLE PRESSURE VALVES IN HYDROCEPHALUS PATIENTS AT THE REHABILITATION HOSPITAL FOR OCCUPATIONAL DISEASES, HO CHI MINH CITY
Main Article Content
Abstract
Objective: To evaluate outcomes of ventriculoperitoneal (VP) shunt surgery using externally adjustable pressure valves in hydrocephalus patients.
Subjects and methods: A retrospective descriptive case series with postoperative follow-up, conducted on 30 hydrocephalus patients who underwent VP shunt surgery with adjustable pressure valves, with a minimum follow-up of 6 months.
Results: Mean age was 41.9 ± 14.25 years; males accounted for 73.3%; traumatic brain injury was the most common etiology (66.7%). Preoperatively, 90.0% of patients were lethargic (GCS 9-13). The Polaris SPV (Sophysa) valve was used in 66.7% and Strata II (Medtronic) in 33.3% of cases. At 6 months, 80.0% required at least one valve adjustment. Neurological improvement increased from 40.0% at discharge to 83.3% at 6 months. Good GOS outcomes were achieved in 20.0% at 6 months. Overall complication rate was 33.3%, with shunt obstruction (16.7%) and infection (10.0%) being most frequent.
Conclusion: VP shunt with adjustable pressure valves enables non-surgical optimization of drainage, with progressive neurological improvement reaching 83.3% at 6 months. Shunt obstruction and infection remain the main complications requiring close monitoring.
