Case 1 - preoperative digital subtraction angiography (DSA) showing a very large aneurysm of the right internal carotid artery bifurcation of 22 mm maximum diameter (a-c). Postoperative DSA showing complete obliteration of the aneurysm (d and e). Diffusion- weighted imaging on postoperative day 1 showing no infarction (f and g). T2-weighted imaging at 6 months after the operation indicating no new lesion (h and i).

Case 2 - head computed tomography on the day of admission revealing left frontal intracranial hematoma centered on the caudate nucleus and intra-ventricular hemorrhage, and a suspected large mass lesion in the hematoma (a and b). Digital subtraction angiography (DSA) showing a 28-mm giant aneurysm of the left internal carotid artery bifurcation (c and e). Postoperative DSA showing complete obliteration of the aneurysm (f). Diffusion-weighted imaging on postoperative day 1 showing no infarction (g). T2-weighted imaging at 6 months after the operation indicating no new lesion (h and i).
