Pneumopericárdio após traumatismo penetrante: relato de três casos / Pneumopericardium after penetrating trauma: report of three cases

ABSTRACT

Pneumopericardium after penetrating wound represents a high suspicion for cardiac wound. Some authors recommend thoracotomy to discharge a cardiac lesion. We present three cases of post-traumatic pneumopericardium one following a gunshot wound and two following a stab wound and discuss about diagnosis and treatment. None showed clinical signs of cardiac tamponade. Diagnosis was made by chest x-ray. Pneumopericardium was identified at the initial evaluation in two patients, who had concomitant hemothorax and underwent chest drainage. The patient with penetrating thoracic wound by gunshot pneumopericardium developed 24h after trauma. Treatment was directed to the associated lesions without specific measurements for pneumopericardium. This aproach was safe in these patients.
