Pre and Post t-PA/Angioplasty Middle cerebral artery (MCA). (a) There is an acute thrombus (arrow) in the M1 MCA segment (right). The intravenous t-PA has dissolved the supraclinoid ICA thrombus, but no effect on the MCA thrombosis which warranted mechanical endovascular therapy. (b) Postpenumbra device and angioplasty there is TIMI 3 flow in the MCA (left)

Also observed was near-total stenosis of the right common carotid artery (CCA) [Figures 1 and 2].
Pre and Post t-PA/Angioplasty Common carotid artery (CCA). (a) Severe stenosis in the CCA at the origin (Arrows). (b) Temporary stents in the CCA and subclavian artery (Arrows). (c) Postangioplasty CCA

CTA of the aortic arch [Figures 3 and 4] showed soft tissue thickening around the aortic arch extending into the great vessel origins.
Pretreatment/Post ET CTA of the neck (axial view). (a) CTA axial view show nearly occluded right CCA (thin blue arrow) with minimal cresenteric flow and extensive soft tissue thickening (thick blue arrow) in and around the wall of the vessel. Also seen is the left CCA (thick red arrow). (b) Right (red) and Left (blue) CCA

CTA of the aortic arch [Figures 3 and 4] showed soft tissue thickening around the aortic arch extending into the great vessel origins.
Posttreatment CTA of the neck (axial view). (a) CTA showing improvement in the caliber and soft tissue deposition of the CCA. Thin blue arrow: improvement in the soft tissue thickening in the wall. Thick red and blue arrows denote Right and Left CCA, respectively. (b) Again shown is the reduced soft tissue deposition in the vessel wall. Arrow denotes Right and Left CCA

Repeat imaging [Figure 5] revealed significant improvement in the degree of soft tissue thickening around the aortic arch and the proximal brachiocephalic vessels.
