A, Left ICA angiography depicting 1 medium-sized aneurysm (7 × 9 mm) located at the callosomarginal artery and 1 small aneurysm (4 × 3 mm) located at the superior parietal artery bifurcation (patient 5). B, Flow stagnation immediately after the deployment of 2 telescopic PEDs (25 × 14 mm + 25 × 20 mm). C, Flat panel CT reconstruction shows successful stent implantation and correct vessel wall apposition. D, Eighteen-month DSA follow-up shows incomplete occlusion (short arrow) (OKM B2) and near-complete occlusion (long arrow) (OKM C2) of the aneurysms.

A, Patient 11 with a right 3 × 3 mm aneurysm originating from the callosomarginal bifurcation. B, Flat panel CT scan confirms correct vessel wall apposition of a single Silk (2 × 15 mm) stent. Ten days after treatment, due to inadvertent discontinuation of the dual-antiplatelet therapy, the patient was admitted to the emergency department with severe left hemiparesis (C). An urgent brain CT angiography shows occlusion of the right A2 distal to the stent (white arrow). D, Diffusion-weighted MR imaging detects an acute ischemic lesion on the territory of the right pericallosal artery. E, Because of the FLAIR positive for lesions (the patient arrived at the hospital 20 hours after the onset of the symptoms), no acute medical and endovascular treatments were performed. F, DSA was performed to confirm the complete stent occlusion (black arrow). The patient was discharged with severe left hemiparesis (mRS 4) and dual-antiplatelet therapy.

A, Patient 4 with a small left A2/A3 aneurysm located at the callosomarginal artery bifurcation. After an attempted coil embolization, due to the instability of the microcatheter inside the aneurysm (related to the tortuosity of the aortic arch and the cervical ICA), the aneurysm was treated with a flow-diverter stent. B, Flow stagnation immediately after deployment of a single PED (2.5 × 14 mm). C, Postintervention flat panel CT reconstruction shows adequate aneurysm neck coverage and proper vessel wall apposition. D, Twelve-month DSA follow-up shows complete occlusion of the aneurysm (black arrow).
