Endovascular Treatment of Intracranial Kissing Aneurysms: Technical Feasibility and Clinical Outcomes

Kissing Aneurysms of the Posterior Inferior Cerebellar Artery Treated by Anchor Coil Technique and Stenting from the Contralateral Side: A Case Report

“…Kim et al reported that 59.7% of the cases required an adjunctive technique. 3) In our case, the neck of the kissing aneurysms was broad, and the height of each aneurysm was low, allowing for the possibility of microcatheter deviation during stenting. To prevent microcatheter deviation during the stenting, the anchor coil technique was employed.…”

“…2) According to reports of 32 cases, 22 (61.1%) were internal carotid arteries, 7 (19.4%) were anterior communicating arteries, and only 1 (2.8%) was in the vicinity of VA-PICA. 3) No previous reports of endovascular treatment for VA-PICA kissing aneurysms are available in the literature.…”

“…Thus far, there have only been few reports on kissing aneurysms near the vertebral artery-posterior inferior cerebellar artery (VA-PICA). 3) In some cases, VA-PICA aneurysms are so complex that it is difficult to gain easy access through open surgery, and reports of endovascular treatment have been increasing in recent years. 4) However, it may be difficult to treat VA-PICA aneurysms endovascularly if the neck is wide or the branches are at a steep angle from the VA. [5][6][7][8] Herein, we describe the first case of VA-PICA and nonbranched PICA kissing aneurysms that were successfully treated with contralateral stenting after the anchor coil technique from the ipsilateral side.…”
