초록

목적 심각한 증상이 없는 파열된 급성뇌동맥류에서 스텐트를 이용한 코일 색전술 기법의 안전성과 유효성을 평가하고, 지주막하출혈 환자에서 스텐트 자체의 유용성을 평가해 보고자 한다. 대상과 방법 2017년 1월부터 2019년 6월까지 심한 증상이 없는(헌트 앤드 헤스 등급 3 이하) 파열된 뇌동맥류에 대해 코일 색전술로 치료받은 118명의 환자를 대상으로 하였다. 스텐트를 사용한 56명과 스텐트를 사용하지 않은 62명에 대해 시술 이후 합병증, 6개월 수정 랜킨척도, 6개월 영상의학적 결과에 대해 비교하였다. 결과 스텐트를 사용한 군과 스텐트 사용하지 않은 군에서 좋은 임상 결과의 비율(수정 랜킨척도 2 이하)과 출혈성 및 허혈성 합병증의 비율은 유의한 차이를 보이지 않았다. 그러나 스텐트를 사용한 군은 6개월 추적 뇌혈관조영술에서 재개통률이 낮았다(20.0% 대 39.3%, p = 0.001). 결론 심한 증상이 없는(헌트 앤드 헤스 등급 3 이하) 파열된 뇌동맥류의 코일 색전술에서 스텐트의 사용은 임상 결과와 유의한 관련성이 없었다. 스텐트를 사용함으로써 추적 뇌혈관조영술에서 재개통률이 감소하였다.

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.
