@entity1 @entity438 @entity439 @entity397 @entity1756
The clinical characteristics of elderly @entity1 with multiple @entity438 were studied. A total of 481 @entity1 , in whom the exact location of their @entity1756 could be confirmed, were classified into two age groups, that is, those aged 59 years or younger (group 1: 247 cases, 51%) and those aged 60 years or older (group 2: 234 cases, 49%). The incidences of @entity439 were 30% for group 1 and 27% for group 2. This difference is statistically not significant. The rate of @entity439 was less frequent in males than in females in group 2, whereas no difference could be found in group 1. The age distribution of @entity1 with @entity439 was basically similar to that of @entity1 with single @entity439 . While the highest @entity397 rate was observed in the anterior communicating @entity438 of both groups, this tendency was more prominent in group 2 (79%) than in group 1 (59%). The @entity397 rates for other sites in group 2 were 50% for @entity438 , 40% for internal carotid @entity438 and 28% for @entity438 . The pattern of surgical outcome showed no major differences between multiple and single @entity439 in either group 1 or 2. However, group 1 had better surgical results than group 2. Even though the surgical outcome for @entity439 in elderly @entity1 was satisfactory, awareness of the probability of @entity397 at each site is helpful, especially when it is necessary to decide whether @entity439 should be operated on or not.
