Abstract

To evaluate the roles of craniotomy and aspiration in the treatment of pyogenic brain abscess throughout 30 years of computerized tomography. A retrospective study of 224 patients who were surgically treated at Istanbul Medical Faculty, Department of Neurosurgery between 1982 and 2012 was undertaken. The records were analyzed for demographic, clinical and radiological findings, surgical interventions (resection, free-hand aspiration and image-guided aspiration), data regarding abscesses (etiological factors, site, size, number, localization and identified microorganism), corticosteroid and antibiotic usage and complications, and the outcomes were reviewed. The male-to-female ratio was 2.2, and the mean age was 26.2±1.25 years. The most common presenting symptom was headache (56.7%), followed by nausea and vomiting (28.5%). Otitis media and mastoiditis were the most common causes of abscess (41.9%), and 44 patients had multiple abscesses. Aerobic gram-positive microorganisms were the most frequently isolated pathogens in culture (51.5%). Primary surgical interventions were as follows: craniotomy and resection (38.8%), free-hand aspiration (49.1%) and image-guided aspiration (12.1%). The aspiration-to-resection ratio was 1.36 (64...Continue Reading
