Endovascular Treatment of Superior Cerebellar Artery Aneurysms

Özet

AIM: To present our experience on superior cerebellar artery (SCA) aneurysms treated with embolization by using currentendovascular techniques.MATERIAL and METHODS: 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.RESULTS: Endovascular treatment was the primary treatment method for SCA aneurysms during the study period. Twenty threepatients (15 female, 8 male) with a mean age of 50.6 years, 12 of whom with subarachnoid hemorrhage were treated. Treatmentsincluded coiling (56%), stent assisted coiling, stentriever assisted coiling, Y stent assisted coiling and flow diversion with eitherflow diverter placement or telescopic stenting. Two patients died secondary to consequences of subarachnoid hemorrhage. Theoutcome of 1 patient was Modified Rankin Scale (mRS) 3 and the outcome of remaining 20 patients was mRS 0. The rates ofaneurysm occlusion according to Raymond-Roy classification were: class 1 in 11 patients, class 2 in 6 patients and class 3 in 2patients on a mean follow-up of 15.3 months. Only one patient required retreatment.CONCLUSION: Current endovascular techniques are able to address the high rate of recanalization and retreatment of SCAaneurysms which are currently the major drawbacks associated with primary coiling when compared with surgical treatment. Itremains to be shown if use of these latest techniques are associated with increased risk of thromboembolic events.
