On (b)(6) 2011, a subject participating in the (b)(6) clinical trial (subject id (b)(6)), underwent initial implantation of the maestro rechargeable system.On (b)(6) 2016, this subject underwent a revision procedure under general anesthesia to reposition the neuroregulator due to discomfort caused by the neuroregulator position near the bra line.The repositioning procedure was uneventful and the device continued to work well after surgery.There were no complications and the subject was discharged to home the same day.On (b)(6) 2016, the subject was admitted to the hospital for observation due to severe pain at the neuroregulator site.Ct revealed a hematoma on the left side of the abdominal and chest wall.There was no sign of active bleeding and the subject was in stable condition.This subject has a history of type 2 diabetes mellitus and obstructive sleep apnea.During the hospital stay, blood glucose levels were elevated (250-300's) and endocrinology evaluation and follow-up were completed.Cpap at night and supplemental oxygen via nc (4l) were used for spo2 89-90 (normal<95-100%).The subject has a history of asthma and smokes 1 pack per day.The pain was managed with norco as needed.The subject was discharged to home on (b)(6) 2016.On (b)(6) 2016, the subject presented to the emergency department for evaluation of dark drainage and blood from the incision that the subject noticed the previous day.Physical examination revealed that the abdominal swelling was much less than previous hospital exam on (b)(6) 2016.The horizontal incision at the location of the neuroregulator was oozing blood from two different spots but there was no large opening of the wound.Ecchymosis was noted on the skin around wound opening.Pinpoint pressure was applied for 15 minutes and hemostasis was not achieved.The subject was taken to the operating room for wound exploration and definitive drainage to reduce the risk of infection.The incision was reopened and roughly 150 cc of old blood and clots were evacuated.The surgeon indicated that the neuroregulator and leads were intact following the procedure.A pressure dressing was applied with the abdominal binder in place.The subject recovered uneventfully and was discharged to home the same day.The subject was seen in clinic on (b)(6) 2016 for suture removal and the wound had a small amount of erythema.The subject was scheduled for a follow-up wound check visit in two weeks.On (b)(6) 2016, the subject presented to the emergency department complaining of fever, chills, diaphoresis, increased left upper quadrant pain, especially with breathing, and dark yellow drainage from the wound the prior night as well.She also reported uncontrolled blood sugars (200-400s) despite compliance.The subject reported nausea without vomiting.Evaluation revealed tachycardia with heart rate of 115 and white count of 25,000.Diffuse upper abdominal tenderness to palpation both in the upper left and upper right was present.Blood cultures (x1) were obtained.A bedside incision and drainage was performed of an infected seroma over the neuroregulator site.The wound was irrigated, packed with moist gauze and dressing applied.The subject was admitted to the hospital and started on iv antibiotics (ancef).After irrigating the wound at bedside, the gross purulence encountered suggested that the neuroregulator should be removed under general anesthesia.On (b)(6) 2016, the neuroregulator was removed in the operating room under general anesthesia and the subject tolerated the procedure well.A wound vac was placed over the left subcoastal incision.The subject strongly desired to retain the leads for future re-implantation of a neuroregulator and voiced considerable success with the weight loss regimen.Therefore, the vagal nerve leads were capped and internalized for future implantation pending resolution of current wound infection.The neuroregulator was sent to pathology for examination.Following the procedure, the pain was managed with dilaudid.The subject followed up with endocrinology for management of her diabetes during hospitalization and was discharged to home on (b)(6) 2016.The discharge diagnosis was incisional wound infection, uncontrolled type 2 diabetes and obstructive sleep apnea.
