Event Description

It was initially reported by a nurse that a vns pt experienced "complications" due to unk reason. The pt just had her vns re-implanted on (b)(6) 2010 due to high lead impedance. During f/u with the surgeon's office, it was found that there had been "complications" during the replacement surgery including fibrosis present around the lead body and bleeding that occurred when the surgeon accidently nicked the jugular vein (addressed in mfr report# 1644487-2010-02173). The surgeon's office stated that they did not have any product info regarding the lead. The pt had stayed overnight in the hosp for monitoring but no actions were needed. Moreover, additional info from a company rep indicated there was still high lead impedances after replacement surgery which took place on (b)(6) 2010. The surgeon and nurse indicated that everything was fine in the operating room and system test was ok. The treating nurse checked the pt when she came in for a f/u and said there were still high impedance (>10kohms/eos=10 yrs). The pt was referred for a pin re-insertion and possible lead replacement with a different surgeon. Info from the initial surgeon through a company rep indicated that there was no report of pt trauma or manipulation. Additional info was received from a company rep who indicated the pt underwent pin re-insertion surgery with a different surgeon. There was no high impedance noted after the re-insertion and after using another pulse generator. System diagnostics after generator replaced were ok with dcdc 2 and eos no.
