- Abstract: Stent-assisted coil embolization (SAC) is used for complex wide-necked aneurysms but can expose stent struts to the arterial lumen, leading to thrombosis. Herein, we report two cases of delayed thromboembolic stroke post-SAC. Case 1: A 71-year-old woman had an acute ischemic stroke 2 months after Y-stent SAC for a basilar artery aneurysm, and aspirin was prescribed post-procedure. Diffusion-weighted imaging revealed multiple scattered infarcts of various sizes in the posterior circulation. Case 2: A 72-year-old woman experienced an acute ischemic stroke 3 years post-SAC for a right posterior communicating artery aneurysm. The stroke occurred after discontinuation of antiplatelet therapy. Diffusion-weighted imaging revealed scattered acute infarctions in the right middle and anterior cerebral artery territories. These two cases of delayed thromboembolic stroke after SAC might have been due to stent strut exposure in the arterial lumen and concurrent thrombosis.
