@entity6087 ( @entity6087 ) is one of the most common clinical entities in daily neurosurgical practice. The diagnosis and treatment are well established, but recurrence, complications, and factors related to these problems, especially in the elderly, are not completely understood. This study evaluated the clinical features, radiological findings, and surgical results in a large series of the @entity1 treated at the same institution. 500 consecutive @entity1 (359 @entity1 and 141 @entity1 ) with @entity6087 were treated by burr hole craniostomy with closed system drainage from January 1987 through February 1999. Causes, clinical and computed tomographic findings, surgical results, re-expansion of brain after surgery, and @entity1410 recurrence were statistically analyzed to elucidate the potential risks of @entity6087 . Most @entity1 (89.4%) had good recovery, 8.4% showed no change, and 2.2% worsened. Six @entity1 (1.2%) died, three due to disseminated @entity5642 . Recurrence of @entity1410 was recognized in 49 @entity1 (9.8%), at 1 to 8 weeks (3.5 +/- 1.9 weeks) after the first operation. The brain re-expansion rate at one week after operation was 45.0 +/- 21.4% in @entity1 with @entity1410 recurrence and significantly lower than 55.3 +/- 19.1% in @entity1 without recurrence (p < 0.001). Old age, pre-existing @entity385 , and persistence of subdural air after surgery were significantly correlated with poor brain re-expansion (p < 0.001). Twenty-seven @entity1 (5.4%) suffered @entity260 , of which 13 cases were @entity6477 caused by @entity11885 wound and four cases were tension @entity5745 . Careful hemostasis and complete replacement of subdural @entity1410 by normal saline to prevent influx of air into the subdural space will further improve the surgical outcome for @entity1 with @entity6087 .
