Aneurysm of the distal anterior inferior cerebellar artery at the medial branch: a case report and review of the literature

Distal Aneurysms of Cerebellar Arteries: Incidence, Clinical Presentation, and Outcome of Endovascular Parent Vessel Occlusion

“…This association with AVMs has also been established in other studies. [9][10][11]14 Although surgical treatment in experienced hands is associated with good results, access to the distal cerebellar arteries may be challenging, needing destructive far-lateral transcochlear or translabyrinthine approaches. 8,11,[14][15][16] Because most distal cerebellar artery aneurysms involve the circumference of the small parent vessel, clipping with sparing of the parent artery is mostly impossible; this problem leaves trapping (with risk of ischemia) the only surgical option.…”

“…1,2 Only case reports or small case series have been published, and no precise information is available in the literature regarding the management of distal cerebellar artery aneurysms or the associated long-term results. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Several approaches have been proposed to surgically treat these aneurysms, depending on their size and location. Although direct clipping is possible in some cases, sophisticated surgical techniques such as hypothermic cardiac arrest and bypass construction are often needed.…”

“…Although direct clipping is possible in some cases, sophisticated surgical techniques such as hypothermic cardiac arrest and bypass construction are often needed. [9][10][11][12][14][15][16] On the other hand, endovascular therapy, consisting of occlusion of the parent artery with coils or glue, is simple to perform and often effective. [2][3][4][5][6][7]13 However, this deconstructive approach may lead to infarctions in the territory of the occluded cerebellar artery if collateral circulation is insufficient.…”

Endovascular Approach of a Proximal Anterior Inferior Cerebellar Artery Aneurysm: Case Report

“…There is no difference between laterality, with an almost equal involvement of the right and left sides. 9 In our work, we describe a right AICA aneurysm in a 71-year-old female patient. According Yamakawa et al, 10 AICA aneurysms can be classified into: proximal (extending from the origin of the AICA in the basilar artery to the meatal loop); medium (located in the meatal loop); and distal (following the end of the meatal loop until the distal AICA).…”

Management of Anterior Inferior Cerebellar Artery Aneurysms: Endovascular Treatment and Clinical Outcome

“…[9][10][11][12][13][14][15][16][17][18][19][20][21] Although various surgical approaches have been introduced to access these aneurysms, surgical treatment is often limited due to the complexity of the adjacent neurovascular structure, the presence of brain stem perforators, the narrow and deep surgical field, and the necessity of an experienced surgeon.…”
