[Results of the surgical treatment of intracranial aneurysm].

In the years 1976-1984 in the Department of Neurosurgery, Silesian Medical Academy in Katowice 196 patients were treated surgically for intracranial aneurysms. In the patients with aneurysms in the anterior part of the circulus arteriosus Yasargil's craniotomy was done. In some cases of aneurysms of the posterior cranial fossa suboccipital craniotomy was performed. In 181 cases the aneurysm was isolated by clipping it, in 4 cases it was trapped and in 11 wrapped. Good results were obtained in 60% of cases and bad in 15.9%. Death from extracranial causes occurred in 3 cases. The results of surgical treatment depended on the condition of the patient estimated by the Botterell scale, age, situation of the aneurysm and number of subarachnoid haemorrhages, duration of operation and experience in qualification of patients for surgery and on surgical technique.
