Description

A 72-year-old female patient who had received dialysis for chronic renal failure was immediately admitted to our hospital because of ileus. Because of the obstruction of her shunt, a nephrologist performed reconstruction under local anesthesia in the morning, without changing the operation mode for ICD. Then, the patient showed worsening of ileus. Thus, laparotomy was planned on the same day. At this time, the surgeon noticed her ICD, contacted the manufacturer, and stopped its antitachycardia function. At the same time, the internal memory was examined. This revealed 3 episodes involving the initiation of charging by electro-magnetic interference in the morning operation and, among those, one episode involved the concurrent activation of antitachycardia pacing. This case fortunately did not lead to the shock therapy owing to a shorter duration of application of the electrocautery. However, depending on its previous charging conditions, shock may have occurred even with such short-term application. So, in case of using monopolar electrocautery during the operation, the antitachycardia function of the ICD must be stopped, even though it is a minor surgery.
