A Ruptured Blood Blister-Like Aneurysm that Experienced Regrowth with Coil Compaction Twice in a Month : Case Report / 고신대학교의과대학학술지

ABSTRACT

Unlike other aneurysms, blood blister-like aneurysms(BBA) occur at non-branching sites, are commonly located at the dorsal wall of the supraclinoid internal carotid artery (ICA), and are suspected to arise from dissecting aneurysms. They are typically diagnosed after a bleed because of their small size and unusual site. Therefore, lesions exist after brain computed tomography or magnetic resonance imaging, but they are often not found. In the case of BBA, which have a high risk of recurrence, the treatment is difficult, and selecting the treatment method is also challenging. This paper describes the treatment of a BBA with internal trapping of the ICA that eventually recurred despite performing coil embolization twice.
