INTRODUCTION: The purpose of this study is to investigate the efficacy and safety of mechanical thrombectomy in patients with acute vertebrobasilar artery occlusion (VBAO) using the Trevo Stentriever™ device. METHODS: Twenty patients diagnosed with VBAO underwent digital subtraction angiography (DSA) with the intention to perform mechanical thrombectomy with stent-retrievers between August 2011 and October 2013. Two patients were excluded because another device was primarily used; in two other patients, thrombectomy was not possible. RESULTS: Thrombectomy with the Trevo device was performed in 16 patients. The Stentriever™ was used either as the sole device (56.3 %) or in conjunction with up to four additional devices or techniques. Thirty-three clot retrieval manoeuvres were performed (mean 2.1 ± 1.3, range 1-5); the device could be deployed and retrieved in all manoeuvres (100 %). No device-related complications occurred. Mean duration of the endovascular intervention was 71.8 min (±39.9; range 22-144). Complete or near complete recanalization (thrombolysis in cerebral infarction (TICI) ≥2b) was achieved in 13 patients (81.3 %). Eleven patients (68.8 %) survived and seven patients (43.8 %) showed a good clinical outcome at discharge, defined as modified Rankin Scale (mRS) 0-2 or National Institute of Health Stroke Scale (NIHSS) improvement ≥10 points. Including the two patients in whom thrombectomy was not possible, successful recanalization, good clinical outcome and survival were achieved in 72.2, 38.9 and 61.1 %, respectively. CONCLUSIONS: Thrombectomy in patients with acute VBAO using the Trevo Stentriever™-either as the sole device or in conjunction with other devices-is feasible and seems to be similarly effective and safe as in the anterior circulation compared to reported data in the literature.
