OBJECTIVE: Early rebleeding after coil embolization of ruptured @entity438 is rare, however serious and fatal results of rebleeding have been reported. We studied the incidence and angiographic and clinical characteristics of rebleeding of @entity1756 occurring in the immediate postoperative period after coil embolization. MATERIALS AND METHODS: We analyzed @entity1 who had @entity510 and underwent coil embolization. @entity1 with dissecting @entity439 , @entity4530 -like @entity439 , and @entity2849 were excluded. This study included 330 consecutive @entity1 . The clinical and radiological data of 7 of these @entity1 with acute rebleeding after coil embolization were reviewed. RESULTS: The incidence of rebleeding of @entity1756 after coil embolization was 2.1% (7/330), and all cases of rebleeding occurred in the immediate postoperative period within 3 days after coiling. The radiological characteristics were as follows: anterior communicating artery (ACoA) @entity439 (71.4%, 5/7); presence of @entity1779 ( @entity1779 , 71.4%, 5/7); dome-to-neck ratio < 2 (42.9%, 3/7); presence of @entity4530 (42.9%, 3/7); and subtotal occlusion of @entity439 after coiling (14.3%, 1/7). A thrombolytic agent was administered in 1 @entity1 and continued anticoagulation was performed in 2 @entity1 . Rebleeding @entity1 showed a very poor outcome (Glasgow Outcome Scale 1, 85.7%, 6/7). CONCLUSION: The prognosis of early rebleeding was very poor. Location of @entity439 on ACoA, the unilateral hypoplasia of A1 segment, presence of @entity1779 and @entity4530 , and adverse events during the procedure were probably associated with early rebleeding of ruptured @entity438 in the immediate postoperative period after coil embolization.
