Delayed XXXX of a previously coiled unruptured anterior communicating @entity438 : case report.

@entity1 @entity1756 @entity75 @entity439 @entity397 @entity6151 @entity438
OBJECTIVE AND IMPORTANCE: We describe a case of an unruptured anterior communicating @entity439 that was treated successfully with Guglielmi detachable coils, which subsequently ruptured 23 months after initial therapy. This report discusses only the second published case of an unruptured lesion that was well embolized (>95% occlusion) and stable at 6-month angiographic follow-up that ruptured in a delayed fashion almost 2 years after the primary procedure. CLINICAL PRESENTATION: An 80-year-old @entity1 presented in Hunt and Hess Grade IV as a result of a @entity6151 communicating @entity438 . The @entity1 had undergone endovascular therapy 23 months earlier with documented nearly complete (1-mm residual neck) occlusion at 0 and 6 months. INTERVENTION: The @entity1 underwent diagnostic catheter angiography at the time of admission, which revealed a 10-mm @entity439 adjacent to the previously embolized lesion. No further therapy was administered, and the @entity1 died within 24 hours as a result of ictus. The request for an autopsy was denied. CONCLUSION: @entity1756 after Guglielmi detachable coil embolization is a rare event. Most cases involve previously @entity75 . To the best of our knowledge, only one previous case of delayed @entity397 of an unruptured @entity439 that was managed endovascularly has been published in the English-language literature. This second case points to the need for vigilance in the follow-up of @entity1 with @entity75 .
