A series of 49 consecutively treated @entity1 with 52 @entity438 (BA) is presented. Thirty-nine @entity439 arose at the BA bifurcation, 11 at the origin of the @entity76 ( @entity76 ), and two from the upper BA trunk just below the @entity76 . The @entity1 population consisted of 36 @entity1 and 13 @entity1 , with a mean age of 50 years (range 23-74 years). Of the 35 @entity1 presenting with @entity510 , 10 were Grade I, 10 were Grade II, 11 were Grade III, and four were Grade IV according to the Hunt and Hess scale. Treatment consisted of @entity439 neck clipping in 28, proximal occlusion of the BA in three, and endovascular therapy with coils in four @entity1 . The remaining 14 @entity1 with @entity439 underwent direct neck clipping. Postoperatively, 38 @entity1 developed @entity892 in at least one direction of gaze but this had resolved in 31 of them at the last follow-up evaluation. There were four deaths (8.2%): two as a result of rebleeding following coil compaction at 8 days and 9 months posttreatment, respectively; one as a result of @entity2553 ; and one as a result of @entity1188 after proximal occlusion of the BA in a giant bifurcation @entity439 . Of the surviving @entity1 , 33 (67.3%) made an excellent recovery, seven (14.3%) made a good recovery, and five (10.2%) were in poor condition at the last follow-up review. Direct microsurgical clipping of most @entity439 of the BA apex region can be performed with acceptable rates of morbidity. These data from an unselected series of @entity1 in a general hospital provide a basis for comparison with developing alternative techniques.
