Fatal cerebral edema following angiocardiography: a case report.

We describe a case of fatal reaction to angiocardiography following investigation of tetralogy of Fallot. This happening has occurred only once in 8300 procedures in our laboratory. It was due to cerebral edema. Although a recognized, but very rare, hazard following injection of contrast material, we found no way in our case of either predicting the outcome or its possible recurrence.
