['The aim of this prospective study was to assess vascular integrity after stent-retriever thrombectomy.', 'Dissection, contrast medium extravasation, and vasospasm were evaluated in 23 patients after thrombectomy with biplane or 3D-digital subtraction angiography and 3-Tesla vessel wall MRI.', 'Vasospasm was detected angiographically in 10 patients, necessitating intra-arterial nimodipine in 2 of them. Contrast extravasation, intramural hemorrhage, or iatrogenic dissection were not detected on multimodal MRI in any patient even after Y-double stent-retriever technique.'] Does multimodal 3 Tesla MRI confirm intact arterial wall in acute stroke patients after stent-retriever thrombectomy?
