MRI of the brain showing acute ischemic stroke in the left anterior choroidal artery region (a), as occluson of left carotid internal artery was confirmed, thrombectomy was performend, however, even after two attempts only partial recanalization was achieved with residual subocclusive stenosis (arrow) and insufficient anterograde flow (b). The last picture (c) showing the end:result after thrombectomy and urgent intracranial stenting of left carotid internal artery.

Subsequent imaging confirmed the previously diagnosed ischemic lesion (Figure 1).
Urgent angiogram showed in-stent restenosis in its distal parts (reaching the M1 segment of left middle cerebral artery:thin arrow) as well as thrombus formation of the distal edge of the stent, with attenuation of distal blood flow (thick arrow, picture a). Control angiography (picture b) showing only residual stenosis (thin arrow) after thrombus resolution.

An urgent angiogram was performed, demonstrating restenosis in the distal segments of the stent (extending up to the M1 segment of the left ACM) as well as the formation of a thrombus at the distal edge of the stent (Figure 2).
