Model Number 304-20

Event Type  Injury  
Event Description

Reporter indicated a newly-implanted vns pt was hospitalized for a jugular inclusion. No complications occurred during the surgical procedure itself. Vns diagnostics with the newly implanted vns system were within normal limits. Per the reporter, the pt was taking valproic acid and depakote medications prior to the surgery. Depakote medication is nonspecific cox2 inhibitor (similar to aspirin) and causes oozing during neurosurgical procedures. It is a known practice to give a small dose of desmopressin medication to pts on valproic acid and depakote prior to surgery. Desmopressin medication is believed to cause a release of von willebrand factor, thereby transiently correcting platelet aggregation defects. It is believed the jugular inclusion was caused by blood hypercoagulation from the medication given preoperatively. The pt was placed on heparin medication and the pt was reported as stable. Attempts for further information are in progress.
