The prognosis of intracranial saccular aneurysms when the surgeon refused surgery

Despite our basic policy of performing intracranial definitive surgery whenever possible in cases of intracranial saccular aneurysms, we have had 80 patients with non-radically treated aneurysms. This investigation is based on an analysis of the prognosis in 54 cases where we refused definitive surgery; it provides insight into the factors and circumstances leading to the use of treatment of secondary choice, conservative rather than definitive treatment.
