Presentation transcript:

Preprocedural CT and procedural and follow-up angiograms of a 39-year-old female patient with a distal PICA aneurysm. Preprocedural CT and procedural and follow-up angiograms of a 39-year-old female patient with a distal PICA aneurysm. A, CT angiography reconstructed on a sagittal projection shows a saccular aneurysm in the PICA. B, A preprocedural DSA image depicts a 7-mm saccular aneurysm located in the tonsillomedullary segment of the left PICA. C, A roadmap DSA image obtained during the procedure shows the catheterization of the distal PICA for stent placement. This image also demonstrates that the aneurysm has a very complex morphology without a definable neck. D, A nonsubtracted angiography image shows the deployment of the stent into the PICA. Please note the compaction and expansion of the stent across the orifice of the aneurysm. E, A 12-month follow-up DSA image reveals the reconstruction of the parent artery and no aneurysm filling. F, The 24-month follow-up DSA image confirms the stable occlusion of the aneurysm. K. Aydin et al. AJNR Am J Neuroradiol 2017;38:2131-2137 ©2017 by American Society of Neuroradiology
