				        	 Purpose:To evaluate the safety and efficacy of stent-assisted coil embolization (SAC) in acutely ruptured cerebral aneurysms without severe symptoms, and thus, the usefulness of the stent itself in patients with subarachnoid hemorrhages. 
				        	
Materials and Methods:From January 2017 to June 2019, 118 patients were treated with coil embolization for acutely ruptured cerebral aneurysms without severe symptoms (Hunt & Hess grade ≤ 3). The periprocedural complications, six-month modified Rankin scores (mRS), and six-month radiologic outcomes were compared between 56 patients with SAC and 62 patients without SAC (non-SAC).
Results:The rate of good clinical outcomes (mRS ≤ 2), as well as the rate of hemorrhagic and ischemic complications, showed no significant difference between the SAC and non-SAC groups.Moreover, compared to the non-SAC group, the SAC group showed a lower recanalization rate on the six-month follow-up angiogram (20% vs. 39.3%, p = 0.001).
Conclusion:Although stent use was not significantly associated with clinical outcomes in coil embolization of ruptured cerebral aneurysms with non-severe symptoms (Hunt & Hess grade ≤ 3), it significantly decreased the rate of recanalization on follow-up cerebral angiograms.
