The presence of @entity438 in association with @entity2758 has been well documented. @entity439 have been described in typical proximal sites along the feeding system to the @entity2758 , in abnormal distal locations along feeding vessels, and in sites remote and apparently hemodynamically unrelated to the @entity2758 . Little attention has been focused on the most appropriate medical and surgical care of @entity1 harboring these lesions. Since 1977, 22 @entity1 with this combination of lesions have been evaluated at our institution. Nine @entity1 (41%) presented after @entity932 . The remaining 13 @entity1 were investigated because of @entity410 in 5 @entity1 (23%), @entity10 in 4 @entity1 (18%), and progressive @entity63 in 4 @entity1 (18%). Among the @entity1 suffering @entity932 , 78% had bled from an @entity439 , with 22% having hemorrhaged from their @entity2758 . All 7 of the @entity1 who suffered aneurysmal @entity548 bled from atypical distal @entity439 on major feeding vessels. Our experience and that of others has led us to believe that the safest approach to @entity1 with this combination of lesions is to treat the @entity439 before microsurgical resection of the associated @entity2758 . Hemodynamic changes associated with the abrupt elimination of an @entity2758 may place associated @entity439 at immediate risk.
