Endovascular surgery for proximal posterior XXXX : an analysis of Glasgow Outcome Score by Hunt-Hess grades.

@entity1 @entity439 @entity5487 @entity1276
OBJECTIVE: Proximal posterior @entity5487 represent a subset of posterior circulation @entity439 that can be routinely treated with either clipping or coiling. The literature contains limited numbers of @entity1 with proximal @entity5487 treated with endovascular surgery. We report our experience with endovascular surgery of proximal @entity5487 with emphasis on @entity1 with poor Hunt-Hess grades. METHODS: We reviewed 31 consecutive @entity1 with proximal @entity5487 who were treated with endovascular surgery. The following data were analyzed: age, sex, size of @entity439 , Hunt-Hess grade at presentation, Fisher grade at presentation, angiographic result after embolization, complications, number of days hospitalized, duration of follow-up, angiographic follow-up results, and Glasgow Outcome Score at follow-up. RESULTS: Excellent angiographic occlusion was achieved in 30 of 31 (97%) @entity1 . Clinical follow-up with Glasgow Outcome Score was performed on every @entity1 an average of 10 months later. Twenty-one of 31 (68%) @entity1 had good outcomes (Glasgow Outcome Score I or II) at follow-up. Of the @entity1 who presented with a favorable clinical grade (Hunt-Hess 0-III), 13 of 15 (87%) had good outcomes at follow-up. Of the @entity1 who presented with a poor clinical grade (Hunt-Hess Grade IV or higher), 8 of 16 (50%) had good outcomes at follow-up. CONCLUSION: This series demonstrates the safety and efficacy of endovascular surgery for proximal @entity5487 . Many @entity1 with poor Hunt-Hess grades from ruptured @entity5487 ultimately had a good outcome. This could be secondary to early, aggressive treatment of @entity1276 and the minimally invasive nature of the endovascular approach.
