Abstract
✓ Sixty-two cases of brain abscess with congenital cyanotic heart disease are reviewed. A sharp peak in the age distribution was seen at 4 to 7 years of age. Of 62 cases, 38 (61.2%) had a tetralogy of Fallot, and six had a transposition of the great vessels. The majority of these abscesses were supratentorial and 76% of abscesses were found in the frontal, temporal, and parietal lobes. Multiple abscesses were present in 19.4% of cases. Sterile cultures were obtained in 61% of the abscesses, and the increasing percentage of sterile cultures seems to be the result of broad-spectrum antibiotic therapy. The overall mortality rate was 37% but there were no deaths after surgical excision secondary to aspiration. Since the introduction of computerized tomography, aspiration without total excision has produced good results, and therefore it is believed that the number of cases which are cured with aspiration therapy alone will gradually increase in the future.
