This paper summarizes the clinical presentation, location, surgical management, and results in 32 patients with cerebral aneurysms. Surgical mortality has been 21.9% for aneurysms (all grades). For good risk aneurysms (Botterell 1 and 2), the surgical death rate was 8.0% (2/25). Clinical presentations and techniques of treatment are summarized.

This paper summarizes a 26.5-year experience in one centre with intracranial tumefactions in children. In 337 craniotomies done on 285 patients, the death rate within 30 days of operation was 6.7% for cases and 5.6% for procedures. Since 1965, the case and operative mortalities have been 2.0 and 1,7%, respectively. There have been no operative deaths in the last 109 patients, 124 craniotomies, done during the past 6.5 years. Operative mortality for primary procedures was 6.0%, 1.5% since 1965. For patients operated upon more than once (52 times on 38 patients), the case mortality has been 5.3%, procedural mortality 3.8%; since 1965 these figures have been 3.8 and 2.8%, respectively. The operative deaths are analysed, and some conclusions drawn. At the present time, surgical mortality from intracranial tumefactions in children should be less than 5%.
