1. Endovascular coil occlusion of an enlarging carotid artery pseudoaneurysm.
Endovascular coil occlusion of an enlarging carotid artery pseudoaneurysm. Sagittal CTA reconstruction (A) of a 23-year-old man status post motorcycle collision demonstrates a small blister pseudoaneurysm of the distal right internal carotid artery. Follow-up sagittal (B) and axial (C) CTA and lateral angiographic (D) images show interval pseudoaneurysm enlargement (arrows) without flow-limiting stenosis. Posttreatment DSA (E) following placement of 9 detachable coils demonstrates minimal residual filling of the aneurysm sac (arrow). Postcontrast MRA (F) at 5.5 months demonstrates improvement in the vascular caliber and no residual pseudoaneurysm filling.
