Hydrocephalus affects many types of individuals, and ventriculoperitoneal (VP) shunts are still the most common treatment method. Even with all of the progress and new ideas over the years, shunt failure still remains a major issue in the hydrocephalus community. An estimated 30-50% of shunts fail within 2 years, with valve failure accounting for approximately 15% of revision surgeries. A <\/span>recent review published in World Neurosurgery<\/span><\/a> examined the evolution of shunt valves, how they have improved over time, and challenges that still arise. Here’s what you need to know:<\/span><\/p>\n Early attempts to relieve pressure buildup involved mechanisms like skull punctures and external drains that often resulted in infection or overdrainage. Then in the 1960s, subcutaneous reservoirs \u2013 surgically implanted devices that can access body cavities or blood vessels for drainage \u2013 allowed doctors to remove cerebrospinal fluid (CSF) manually which seemed ideal but still presented many challenges. They required frequent tapping and had a high risk of infection.<\/span><\/p>\n A breakthrough emerged when valves were added to shunt systems because they allowed for more control over CSF drainage with a reduced risk of infection.<\/span><\/p>\n <\/p>\n
