Presentation transcript:

A 63-year-old female with a giant left internal carotid artery, cavernous segment aneurysm undergoing treatment with PED. Angiography from a catheter positioned within the left internal carotid artery (A) shows the giant cavernous aneurysm. A 63-year-old female with a giant left internal carotid artery, cavernous segment aneurysm undergoing treatment with PED. Angiography from a catheter positioned within the left internal carotid artery (A) shows the giant cavernous aneurysm. A lateral native image (B) after the construct has been placed demonstrates contrast stasis within the dependant aspect of the aneurysm. The construct is easily visualized on fluoroscopy through the osseous structures of the skull base. Computed tomographic angiogram (CTA) obtained on post-operative day (POD) 1 shows the construct in place within the carotid artery and persistent filling of the aneurysm with contrast (C). There is no significant artifact created by the construct. The surrounding anatomy is easily evaluated. On POD 11, the patient experienced worsening of her headaches and left retro-orbital pain along with diplopia, A POD 12 CTA shows complete thrombosis of the aneurysm (D). The interval exacerbation of symptoms was attributed to transient inflammation and mass effect attributable to the process of aneurysm thrombosis. These symptoms completely resolved over the next 2 months. Follow-up left carotid angiography (E) performed 5 months after treatment shows complete occlusion of the aneurysm with anatomical remodeling of the carotid artery. D Fiorella et al.
