Double LVIS Jr. Stenting of a Ruptured Proximal Anterior Inferior Cerebellar Artery Aneurysm: A Case Report

Abstract

A 53-year-old woman presented with headache. CT demonstrated subarachnoid hemorrhage. DSA revealed no evident source of bleeding. On day 10, she complained of sudden headache and CT demonstrated rebleeding. On repeated DSA, an aneurysm at the anterior pontine segment of the right AICA was found. An LVIS Jr. stent was deployed at the right AICA including the aneurysm. On postoperative day 23, the aneurysm ruptured again. Another LVIS Jr. stent was deployed at the same area. On day 56, she was discharged home without neurological deficit. Conclusion: Intracranial aneurysms not indicated for coil embolization or parent artery occlusion are difficult to treat. Overlapping stenting may be a treatment option for such aneurysms.

Anterior inferior cerebellar artery aneurysm with proximal parent artery stenosis: A case report

“…The anatomical features of premeatal segment aneurysms have not been well characterized; however, in our patient and in several previous reports [8] , [9] , [10] , [11] , the ipsilateral posterior inferior cerebellar artery was hypoplastic or aplastic, which may have caused increased hemodynamic stress on the AICA. In another report, the premeatal segment aneurysm was located along an arterial bend, a region congenitally vulnerable to aneurysm development [12] . Either feature may underly development of AICA aneurysms at nonbranching sites.…”
