The patient reported getting infections in the past from past surgeries, which were not vns surgeries. The patient underwent vns generator explant surgery. The patient later provided a detailed timeline of the events. At the post-op follow up, there was redness at the neck incision. The following day, the patient awoke to pain and a lump on the neck. The pain increased over the day and the incision opened with a purulent discharge. The patient went to the er and received iv antibiotics. The surgeon saw the patient at the hospital the next day and the patient was discharged with oral antibiotics. On the next follow up, the patient felt that the neck incision appeared better. However, the generator incision was red and appeared to have an infection. Cultures indicated both aerobic and anaerobic bacteria. The patient stated that she always had a propensity to infections following surgery. A review of device history records showed that both the lead and generator were sterilized prior to distribution. No additional relevant information has been received to date.

 
Event Description

It was reported by the surgeon's office that the patient presented to the surgeon's office and the incision site was still draining. It was stated that the surgeon used a stitch or two and changed the patient's antibiotic. The patient later contacted the manufacturer and provided more details. The patient had her stitches removed previously at a follow-up appointment with the surgeon. The surgeon had placed steristrips on the wound. Later that day, the steristrips and bandage came off, leaving the patient with an open wound. The patient had presented to the surgeon's office the next day, where he re-stitched the patient and placed her on the aforementioned antibiotics. Clinic notes were later received indicating that the patient reported scant drainage and no pain. The patient was getting along well tolerating the current antibiotics. The wound was sealed and there was no active drainage or erythema. It was stated that the patient was improving despite the fact that there was a little bit of abnormality on the most recent culture.
