UNASSIGNED: OBJECT Surgery for CSF diversion is the most common procedure performed by pediatric neurosurgeons. The failure rates for shunts remain frustratingly high, resulting in a burden to @entity1 , families, providers, and healthcare systems. The goal of this study was to quantify the risk of a @entity5033 in @entity1 with an existing shunt who undergo an elective intradural operation. METHODS All elective intradural surgeries (cranial and spinal) at Le Bonheur @entity1 's Hospital from January 2010 through June 2014 were reviewed to identify those @entity1 who had a functional ventricular shunt at the time of surgery. @entity1 records were reviewed to collect demographic, surgical, clinical, radiological, and pathologic data, including all details related to any subsequent shunt revision surgery. The primary outcome was all-cause shunt revision (i.e., @entity281 ) within 90 days of elective intradural surgery. RESULTS One hundred and fifty elective intradural surgeries were identified in 109 @entity1 during the study period. There were 14 @entity1 (12.8%, 13 male) who experienced 16 shunt malfunctions (10.7%) within 90 days of elective intradural surgery. These 14 @entity1 underwent 13 craniotomies, 2 endoscopic fenestrations for loculated @entity1276 , and 1 laminectomy for dorsal rhizotomy. Median time to failure was 9 days, with the shunts in half of our @entity1 failing within 5 postoperative days. Those @entity1 with failed shunts were younger (median 4.2 years [range 0.33-26 years] vs median 10 years [range 0.58-34 years]), had a shorter time interval from their previous shunt surgery (median 11 months [range 0-81 months] vs median 20 months [range 0-238 months]), and were more likely to have had intraventricular surgery (80.0% vs 60.3%). CONCLUSIONS This is the first study to quantify the risk of a @entity5033 after elective intradural surgery. The 90-day all-cause shunt failure rate (per procedure) was 10.7%, with half of the failures occurring within the first 5 postoperative days. Possible risk factors for @entity5033 after elective intradural surgeries are intraventricular surgical approach, shorter time since last shunt-related surgery, and young age.
