We retrospectively analyzed 241 registry cases meeting Modified Dandy Criteria, excluding incomplete data (44%). Negative binomial regression, Chi-square tests, and Kaplan-Meier analysis assessed failure rates and predictors. At two years, VP shunts failed 1.38 times more often than LP shunts (95% CI: 0.90–2.10; p=0.139), with no significant predictors identified. Median times to failure ranged from 73.5–158 days. Findings suggest similar failure rates and highlight the need for larger studies using survival analysis to clarify time-dependent risks. 000000910 540__ $$fCC BY 000000910 542__ $$fIn copyright - single owner 000000910 650__ $$aEquipment Failure Analysis$$031675 000000910 650__ $$aCerebrospinal Fluid Shunts$$016379 000000910 650__ $$aIntracranial Hypertension$$031714 000000910 650__ $$aVentriculoperitoneal Shunt$$029846 000000910 650__ $$aPseudotumor Cerebri$$024812 000000910 6531_ $$areliability 000000910 691__ $$aSchool of Medicine$$041369 000000910 692__ $$aDepartment of Public Health and Preventive Medicine$$041444 000000910 7001_ $$aMartin, Richard$$uOregon Health and Science University$$041354 000000910 8564_ $$902489987-b1c5-4a91-8aa3-6cc68219e00b$$s595664$$uhttps://digitalcollections.ohsu.edu/record/910/files/913_etd.pdf$$ePublic$$2ddd4be9a889308a585ab4757d39f73be$$31 000000910 905__ $$a/rest/prod/cj/82/k7/33/cj82k733h 000000910 909CO $$ooai:digitalcollections.ohsu.edu:910$$pstudent-work 000000910 980__ $$aTheses and Dissertations
