Objective: The aim of this study was to define the clinical characteristics of pediatric cerebral aneurysms.
Methods: During the past 30 years, among a total of 3,330 patients treated for cerebral aneurysms, 12 patients were under the age of 18. The authors reviewed the database and imaging studies as sources for identification and analysis.
Results: Seven patients were male and 5 were female. The mean age was 12.9 years old (range: 3~18). Nine patients had ruptured lesions and the remaining 3 had unruptured lesions. Four patients presented with a subarachnoid hemorrhage, and the other 5 patients presented with an intracerebral hemorrhage (ICH). Five aneurysms were located at the posterior cerebral artery or vertebrobasilar artery, 4 at the middle cerebral artery, and 3 at the internal carotid artery, respectively. The giant aneurysm was observed in 2 (18%) patients. Eleven aneurysms were saccular, and 1 was serpentine in shape. No patient had multiple aneurysms. Rebleeding was observed in 3 cases (33%). No child suffered from clinical vasospasm. All but one patient showed a favorable outcome (good: 11, dead: 1).
Conclusions: Pediatric cerebral aneurysms in this study showed a male predominance, a high incidence of presentation with ICH, a location on the distal circulation of the major arteries or on the posterior circulation, and a large or giant aneurysm, high rebleeding rate and a low incidence of vasospasm. The overall clinical outcome was excellent in 91.7% in this study. With the knowledge of these features, aneurysmal obliteration and active brain resuscitation can improve the clinical outcome and prognosis.
