Presentation transcript:

Giant cavernous carotid aneurysm, with the patient presenting with third and sixth nerve palsy due to mass effect (patient 16, On-line Table and Tables 1 and 2), treated with flow modification. Giant cavernous carotid aneurysm, with the patient presenting with third and sixth nerve palsy due to mass effect (patient 16, On-line Table and Tables 1 and 2), treated with flow modification. A, DSA, right ICA injection, oblique posteroanterior view before treatment demonstrates a giant partially thrombosed aneurysm (arrow). B, DSA, right ICA injection, oblique posteroanterior view, immediately following implantation of 3 coaxial PEDs across the neck of the aneurysm, demonstrates significantly reduced flow (arrow). C, Fluoroscopic image demonstrates the implanted PEDs (arrow) and delayed contrast stasis (broken arrow) within the aneurysm. D, Six-month follow-up angiogram demonstrates complete occlusion of the aneurysm and reconstruction of the parent artery. E, T2-weighted axial MR image of the same patient before treatment demonstrates the giant ICA aneurysm (arrow) with associated significant mass effect. F, Follow-up MR image at 12 months demonstrates collapse of the aneurysm and resolution of the mass effect. I. Szikora et al.
