[Pacemaker Dislocation into the Peritoneal Cavity].

A 16-day-old neonate with congenital complete atrioventricular block underwent epicardial pacemaker implantation under the rectus. Four months later, abodominal X-ray imaging revealed dislocation of the generator from the abdomen to the pelvis. The infant was diagnosed with intraperitoneal pacemaker dislocation. However, there were no abdominal manifestations or complications associated with the bowel, urinary tract, and vascular system. Surgical refixation was performed in a hybrid room. Fluoroscopy helped avoid bowel injury when removing the generator from the peritoneal cavity. The pacing lead, which was adherent and entangled with the omentum, was released under direct vision. The generator was placed in a new pocket created in the subcutaneous layer of the anterior fascia of the rectus.
