Presentation transcript:

Plain CT scan of head (a) and prethrombectomy (b) and post-thrombectomy (c, e, f) digital subtraction angiograms in a 58-year-old man with a short history of visual symptoms and vertigo followed by a rapid drop in conscious level. Plain CT scan of head (a) and prethrombectomy (b) and post-thrombectomy (c, e, f) digital subtraction angiograms in a 58-year-old man with a short history of visual symptoms and vertigo followed by a rapid drop in conscious level. Plain CT scan of head (a) shows thrombus in the basilar artery (red arrow) with complex plaque at the vertebral artery origin, confirmed on digital subtraction angiography (b). Following successful thrombectomy (c), with removal of a large cast of thrombus (d) by aspiration, a stent was deployed across the unstable stenotic plaque at the vertebral artery origin (blue arrows, e and f). Basilar thrombi can often be removed in bulk like this, possibly because of their physical composition. Matthew R B Evans et al.
