Stenting of the left internal carotid artery because of an iatrogenic dissection (thick arrows) during distal access maneuver for endovascular treatment of an intracranial cavernous internal carotid artery aneurysm (thin arrows). Selective angiography of the left internal carotid artery. Digital subtraction angiography (a-c) and fluoroscopy (d) before (a, b) and after stenting (c, d) in posterior-anterior (a, c) and lateral projections (b, d), revealing circumscribed dissection of the cervical segment of the left internal carotid artery. Distal access was necessary to treat an intracranial internal carotid artery aneurysm (thin arrow). The carotid stent which was used for stenting is rather radiolucent and hard to depict. The ends of the stent are marked by two dotted lines (c, d).
