Pneumopericardium and pneumothorax after permanent pacemaker implantation.

We present a patient with chronic obstructive pulmonary disease who developed discomfort 2 days after dual-chamber pacemaker implantation via the left cephalic vein approach. The pacer was placed with active-fixation leads without obvious complications. A computed tomography (CT) scan taken in the emergency room showed right pneumothorax and associated pneumopericardium without pneumomediastinum. A three-dimensional reconstruction of CT images confirmed the atrial lead protruding into the pleural space. This lead likely ruptured a bulla causing a pneumothorax followed by pneumopericardium through a pleuro-pericardial communication. Chest tube placement relieved both pneumothorax and pneumopericardium without the need for atrial lead extraction.
