Occlusion sites were proximal ICA\u2013middle cerebral artery (MCA) trunk in 17 patients, proximal ICA\u2013ICA terminus in six, and ICA\u2013MCA\u2013anterior cerebral artery in one. Stent-assisted cervical ICA recanalization was achieved in all patients, with unprotected pre-angioplasty in 24\/24, unprotected stenting in 16\/24 (67%), and protected stenting in 8\/24 (33%), followed by stent-thrombectomy in 25 intracranial occlusions. There was complete recanalization\/complete perfusion in 19\/24 (79%), complete recanalization\/partial perfusion in 3\/24 (13%), and partial recanalization\/partial perfusion in 2\/24 (8%) with no procedural morbidity\/mortality. Mean time to therapy was 3.8\u2005h (range 2\u20135.5) and mean time to recanalization was 51\u2005min (range 38\u201369).
