Abstract
To present our experience on superior cerebellar artery (SCA) aneurysms treated with embolization by using current endovascular techniques. All SCA aneurysms treated by our endovascular team since 2013 were retrospectively evaluated. Clinical information and angiographic findings on presentation, during treatment and on follow-up were noted. Endovascular treatment was the primary treatment method for SCA aneurysms during the study period. Twenty three patients (15 female, 8 male) with a mean age of 50.6 years, 12 of whom with subarachnoid hemorrhage were treated. Treatments included coiling (56%), stent assisted coiling, stentriever assisted coiling, Y stent assisted coiling and flow diversion with either flow diverter placement or telescopic stenting. Two patients died secondary to consequences of subarachnoid hemorrhage. The outcome of 1 patient was Modified Rankin Scale (mRS) 3 and the outcome of remaining 20 patients was mRS 0. The rates of aneurysm occlusion according to Raymond-Roy classification were: class 1 in 11 patients, class 2 in 6 patients and class 3 in 2 patients on a mean follow-up of 15.3 months. Only one patient required retreatment. Current endovascular techniques are able to address the high rate of recanalization and retreatment of SCA aneurysms which are currently the major drawbacks associated with primary coiling when compared with surgical treatment. It remains to be shown if use of these latest techniques are associated with increased risk of thromboembolic events.
Highlights
Superior cerebellar artery (SCA) aneurysms are rare, accounting for 1%–2% of all intracranial aneurysms [12,15]

No patients with SCA aneurysms were referred for surgical treatment of their aneurysms
Summary
Superior cerebellar artery (SCA) aneurysms are rare, accounting for 1%–2% of all intracranial aneurysms [12,15]. SCA aneurysms have been evaluated within case series of posterior circulation aneurysms. Studies strictly focusing on SCA aneurysms are less common due to their low incidence [17]. Surgery for posterior circulation aneurysms, including SCA aneurysms, is difficult because of narrow surgical field and proximity to the thalamoperforating arteries and cranial nerves. Endovascular methods, which have been increasingly used in recent years with advanced technology and practice, have become the standard of care in many centres for the treatment of posterior circulation aneurysms. Institutional case records of the cerebral aneurysms treated by our neurovascular team between January 2013 and June 2018 were analysed. Patients with endovascularly treated SCA aneurysms were identified and retrospectively evaluated.
