INTRODUCTION: There is an absence of widely accepted guidelines for the management of @entity438 ( @entity438 ) owing to a dearth of high-quality evidence in the literature. OBJECTIVE: To better define the incidence of @entity438 , treatment practices, and @entity1 outcomes by performing a Nationwide Inpatient Sample (NIS) database query. METHODS: We queried the NIS database from 2002 to 2011 for all @entity1 with the primary diagnosis of @entity166 ( @entity166 ), @entity510 ( @entity510 ), or @entity438 by ICD-9-CM codes. ICD-9 procedure codes were used to identify @entity1 undergoing neurosurgical or cardiothoracic procedures. RESULTS: The query identified 393 @entity1 with primary diagnosis of @entity166 , @entity510 or @entity438 treated during 2002-2011. The mean age of the @entity1 was 53.5   years; 244 (62%) were male. The majority of @entity1 presented with @entity510 (361; 91.9%). Only 73 (18.6%) @entity1 underwent neurosurgical coiling or clipping for IIA. Of @entity1 undergoing a neurosurgical procedure, 65 had @entity510 ( @entity9528 only 18% of @entity1 with @entity510 ) and 8 had @entity439 ( @entity9528 only 25% @entity1 with @entity439 ). Cardiac procedures were performed in only 72/393 @entity1 (18.3%) @entity1 . Only 67 (18.6%) of the @entity1 with @entity510 and 5 (15.6%) with @entity439 underwent a cardiac corrective surgical procedure. Mortality was significantly higher in those @entity1 managed conservatively (26.7%) than in those who underwent clipping or embolization (15.1%; p<0.001). CONCLUSIONS: In this NIS database study, the majority of @entity1 with @entity438 were managed non-operatively, regardless of @entity397 status. Further investigation is warranted to standardize the management of these lesions.
