O'Chareon S We retrospectively reviewed the 380 patients on whom surgery was performed for
intracranial aneurysms between January 1987 and December 1997. The incidence of multiple intra-
cranial aneurysms (MIA) in our hospital was 8.7 per cent (33/380 cases). The management out-
come of 33 patients with MIA was assessed 6 months after SAH. The outcome was poorer for
patients with MIA than for those with a single intracranialaneurysm (SIA). The mortality and
morbidity in all grades were 24.2 per cent in patients with MIA and 16.7 per cent and 19.6
per cent respectively in those with SIA. Delayed neurological deficit and treatment outcome of
poor grade patients had significant contribution to outcome in patients with MIA, more than in
patients with SIA.
