Event Description
|
A patient reported that she had experienced a weight loss of approximately 150 pounds since being implanted with her vns device in (b)(6) 2012.Follow-up with the patient's physician showed that the weight loss was related to vns and was due to experiencing left vocal cord paresis following the implant in (b)(6) 2012.Per the neurologist, the vocal cord paresis may have caused aspiration and thus diminished oral intake, resulting in weight loss.The family was reportedly well compensated as of (b)(6) 2016.The majority of the clinical symptoms reported are related to bodily structures near the lead site ( voice alteration, dysphagia, nerve damage, and vocal cord paresis ).Additionally, the reported events were not alleviated after generator replacement occurred on (b)(6) 2016.Diagnostics have reportedly been within normal limits with both generators.No additional relevant information has been received to date.
