Baseline frontal DSA projection of the right internal carotid artery demonstrating complete occlusion of the proximal right MCA M1 segment and retrograde filling of distal MCA branches from ACA-MCA pial communications. Baseline lateral DSA projection demonstrates retrograde filling of distal MCA branches from ACA-MCA pial communications.
Frontal and lateral right ICA DSA show stent-retriever in situ (Stryker TREVO XP 6 x 25 mm) highlighting the clot and providing "temporary endovascular bypass".
Final DSA following removal of the stent-retriever demonstrating reperfusion of the previously occluded MCA. TICI 2C angiographic result (some underfilling of small distal parietal MCA cortical branches).
