Treatment of extracranial internal carotid artery dissecting aneurysm with SUPERA stent implantation: Two case reports

Figure 1 Case 1 was a 57-year-old male patient with sudden right limb weakness and vague speech and was diagnosed with cerebral infarction in February 2019. He was ultimately treated using a SUPERA stent. A: Cervical computed tomographic angiography (CTA) volume reconstruction; B: curved surface reconstruction show that the wide-necked dissecting aneurysm was situated on the upper segment of the left internal carotid artery; C: confirmed by digital subtraction angiography (DSA); D and E: The patient underwent SUPERA stent endovascular therapy, the arrow shows the dense stent mesh; F and G: Three months later, cervical CTA showed that the aneurysm had disappeared completely. H: One year later, DSA showed that the internal carotid artery was repaired perfectly.

Figure 2 Case 2 was a 57-year-old man who suddenly felt dizzy and developed unsteady walking in November 2019. He was ultimately treated using a SUPERA stents. A: Cervical computed tomographic angiography (CTA) volume reconstruction; B: digital subtraction angiography (DSA) showed a fusiform dilated dissecting aneurysm with severe stenosis located in the upper segment of the right internal carotid artery, involving the petrous segment; C and D: It was treated with SUPERA stent endovascular treatment, the arrow shows the dense stent reticular wire; E: Three months later, cervical CTA showed that the aneurysm had disappeared completely, and the lumen of the internal carotid artery was unobstructed; F: One year later, DSA showed that the internal carotid artery was repaired perfectly.
