Treatment of ruptured blood blister-like aneurysms with flow diverter SILK stents

Abstract

Implantation of flow diverter stents seems to be a safe and feasible alternative for treatment of ruptured BBAs.

Cerebrovascular complications of transorbital penetrating intracranial injuries

“…With improvements in stent technology, smaller stents and flowdiverter stents are available. These devices allow for the healing of the aneurysmal wall defect over the stent struts even in very fragile, dissecting type aneurysms [42] and decrease the rate of recurrences. We used a flow diverter in one of our patients and believe these devices will be used more frequently in traumatic intracranial aneurysms in the future.…”

Safety and Efficacy of Intravenous Tirofiban as Antiplatelet Premedication for Stent-Assisted Coiling in Acutely Ruptured Intracranial Aneurysms

“…The treatment of ruptured aneurysms with a flow diverter has been reported, but there are still concerns related to the risk of recurrent SAH during antiplatelet therapy while remodeling is underway. 30,31 Further study regarding a viable acute antiplatelet agent for potential flow-diverter cases is important.…”

Endovascular treatment of blister aneurysms

“…5) and Silk (Balt Extrusion) for treatment of blister aneurysms is gaining in popularity and has the potential for becoming the standard of care. 3,5,6,9,10,25,[30][31][32][33]39,49 In their 2017 study of 10 patients with ruptured blister pathology and an average Hunt and Hess score of 1.6 on presentation, Linfante et al noted successful deployment of the PED in 9 patients. 31 Eight of the 9 patients treated with the PED had a 90-day mRS score of 0, and the remaining patient had a score of 1.…”

“…1,37,38,40 It is important to note that although Ohara and colleagues' original paper described aneurysms arising from multiple cerebral arteries, 42 the term blister aneurysm is often restricted to half-dome-shaped aneurysms from nonbranching sites of the dorsal ICA only. 1,18,24,35,38,40,53 Other authors use the term to describe such aneurysms of both the ICA and basilar artery, 3,7,36,48,52 and some authors include such aneurysms of the middle cerebral artery (MCA), anterior cerebral artery (ACA), vertebral artery (VA), posterior cerebral artery (PCA), and posterior inferior cerebellar artery (PICA). 4,15,31,35,45,46,49 Whether blister aneurysms of the dorsal ICA have the same or different pathogenesis and natural history as similarly shaped aneurysms of nonbranching sites of other cerebral arteries has not been proven.…”
