P140 Mechanical thrombectomy with combined stent retriever and contact aspiration in acute basilar artery occlusions

<h3>Introduction</h3> Fast reperfusion after large vessel occlusion (LVO) is a strong predictor of good clinical outcomes in patients with LVO. Therefore, how to improve the mechanical thrombectomy (MT) technique for the first-pass effect is paramount. <h3>Aim of Study</h3> To evaluate safety and efficacy of combined stent retriever and contact aspiration MT technique in acute basilar artery occlusion. <h3>Methods</h3> We have retrospectively reviewed basilar artery occlusions treated with MT and combined technique in our institution in a six months period and analyzed the angiographic and clinical outcomes, including first-pass complete recanalization, number of passes, procedure duration, 90-day modified Rankin Scale (mRS). <h3>Results</h3> We have treated 5 patients with a combined MT technique in a selected period. In all cases complete recanalization was achieved. Mean procedure time, from punction to recanalization, was 55 (45-82) min. In all patients’ groin puncture and femoral artery was used for access. First-pass complete recanalization was achieved in 4 cases, whereas in one case 2 passes were needed for complete recanalization. All cases were performed under general anesthesia. In 2 cases 90-day mRS was 0, in 2 cases was 1, and one patient died from pulmonary complications on the day 14 (mRS 6). <h3>Conclusion</h3> Our series suggests that MT technique with the combined stent retriever and contact aspiration yielded high recanalization rate in acute basilar artery occlusion patients and is a safe and effective method followed by favorable functional outcomes. <h3>Disclosure of Interest</h3> no.
