Abstract:
:Thirty outpatients with unruptured cerebral aneurysms screened by computed angiotomography have been analysed and followed up in our clinic since 1979. Seventeen were men and the age range was 41 to 74 years old (mean 57.7 years). Patients had no or only mild neurological symptoms, such as headache, sensorimotor or speech impairment and others, which were scarcely related to the unruptured aneurysms themselves. It is important to realize that these first aneurysms which remain unruptured, have a primary significance to the individual in the protective aspect of an initial subarachnoid haemorrhage. Operation was successfully performed in fifteen patients. Transient aggravation of previous diseases, e.g. cerebral infarction, occurred in three after operation. Follow-up studies of fifteen patients without operation revealed no change in eight and some worsening or death due to other or previous diseases in six. One died of aneurysmal rupture in the 5th month after its detection. Because of the low operative risk, we advocate the operative treatment of unruptured aneurysms, following careful selection of the indicated patients.
