Rescue stenting after artery occlusion as a complication of an intrasaccular device–assisted coiling embolization: illustrative case

BACKGROUND Endovascular embolization of wide-necked aneurysms can be challenging. The development intrasaccular devices like the Contour has enabled us to approach these effectively by reducing recanalization rates and eliminating need for dual antiplatelet therapy, which is particularly beneficial in case ruptured aneurysms. Although complications from using are rare, it crucial address them properly. In this case, authors highlight how manage artery thrombosis caused device protrusion during aneurysm embolization. OBSERVATIONS This report describes a complication male patient with anterior communicating aneurysm. Following Contour-assisted coiling aneurysm, realignment detachable apex occluded A2 segment right cerebral artery. After failure intra-arterial intravenous tirofiban infusion as well mechanical thrombectomy, self-expanding open-cell stent was deployed involved vessel, achieving successful reperfusion. LESSONS zone that cause occlusion parent vessel after deployment. use rescue maneuver may useful if reperfusion cannot achieved through other methods such aspiration or full-dose therapy.
