Illustrative case of second-stage PED with coil embolization. A Lateral angiogram revealing a large intracranial aneurysm measuring 14.0 mm located in the paraclinoid portion of the left internal carotid artery. B Digital angiogram of coil embolization using microballoon. C Residual cerebral aneurysm state after coil embolization. D DWI study obtained 1 day post-coil embolization, revealing no hyperintense lesions. E Pre-pipeline embolization revealing residual cerebral aneurysm 1 month after coil embolization. F Multiplanar reconstructed dynamic CT scan obtained after dilute contrast injection, showing the deployed PED and coils. G DWI study obtained 1 day post-pipeline embolization, revealing a hyperintense lesion in the frontal lobe. H 6 months after second-stage PED deployment with coil embolization, revealing complete occlusion, OKM D. CT, computed tomography; DWI, diffusion-weighted image; OKMD, OKM, O’Kelly–Marotta grade D; PED, pipeline embolization device
