Endovascular Coil Embolization with Low-Profile Visualized Intraluminal Support Junior Stent for Ruptured Dissecting Aneurysm of Proximal Superior Cerebellar Artery-Case Report and Literature Review

BACKGROUND: Superior cerebellar artery (SCA) aneurysm arising from the SCA itself is rare, and treatment of this aneurysm is challenging because of the important anatomic structures, such as the perforating arteries to the brainstem and cranial nerves. We describe a successful coil embolization with a Low-profile Visualized Intraluminal Support Junior (LVIS Jr.) stent for the proximal SCA dissecting aneurysm. CASE DESCRIPTION: A 50-year-old woman presented with right oculomotor nerve palsy and subarachnoid hemorrhage. Cerebral angiography showed a dissecting wide neck aneurysm at the anterior pontomesencephalic segment of the right SCA (diameter 1 mm). The patient was treated with coiling assisted by an LVIS Jr. stent. Postoperative angiography demonstrated a complete embolized aneurysm and parent artery preservation. CONCLUSIONS: Endovascular treatment assisted with LVIS Jr. stent for proximal SCA dissecting aneurysm arising from small parent artery was safely and effectively feasible.
