[Cardiac tamponade as a complication of ventriculo atrial shunt].

Cardiac tamponade is an uncommon disorder in pediatric patients. We report a case of cardiac tamponade secondary to accumulation of cerebrospinal fluid due to ventriculo-atrial derivation (VAD) disfunction. An 11-month-old girl was assisted because of respiratory distress and tachycardia, without fever. She had a ventriculoatrial derivation, because of hydro-cephalus since two month earlier. The echocardiogram showed a pericardial effusion and the distal VAD located inside the right cardiac ventricle. The distal VAD was retired and replaced between superior cava vein and right atrium. The patient recovered ad integrum without pericardial effusion. In cases of patients with VAD presenting a clinical disorder, it should be ruled out VAD dysfunction or inappropriate placement.
