Model Number 302-20
Event Date 07/01/2009
Event Type  Injury  
Event Description

It was initially reported that the vns pt had surgery where the generator was replaced due to an unk reason. Further follow up with the physician revealed that the pt was experiencing a sudden onset of painful stimulation in the neck and disabled the device. The painful stimulation resolved, however, the pt subsequently had a 50% increase in seizure activity, and therefore, the physician referred the pt to a surgeon. There was no report of any pt trauma. There was also no causal or contributory programming changes, medication changes, or other eternal factors that preceded the onset of the painful stimulation. Device diagnostics provided by the physician, indicate normal device function. During surgery, the generator was replaced and the neck incision was opened to examine the lead strain relief. The surgeon excised some adhesions that had formed around the lead boy and the tie-downs used to secure the lead strain relief. The surgeon also "loosened" the lead strain relief. The pt has been seen for follow-up with the treating physician since surgeon occurred and the device has been programmed back to therapeutic levels and the pt is no longer experiencing painful stimulation.
