Figure 2 Preoperative, intraoperative and postoperative imaging of a 54-year-old female patient with a large carotid-ophthalmic aneurysm. A and B: Pre-operative digital subtraction angiography (DSA) in anteroposterior (AP) and lateral (LAT) views: the giant stained aneurysm in the internal carotid-ophthalmic segment was visible, maximal diameter (20.4 mm), neck size (13.4 mm) and dome-neck ratio of 1.6; C and D: First intraoperative DSA (AP and LAT view) showed that the balloon was placed in the aneurysm neck; E and F: Second intraoperative DSA showed that the bulk of the aneurysm was clipped and not visualized, but a small portion of residual aneurysm was visualized; G and H: After adjusting the clips, third intraoperative DSA displayed that the aneurysm was completely clipped, but the parent artery was slightly narrowed due to the severe calcification of the aneurysmal neck.
