In 11 of the 13 cases, the aneurysm neck was clipped
after thrombectomy. In 2 patients with unruptured aneurysms,
clipping was not attempted because of the presence
of intraluminal thrombus and severe atherosclerosis of
the parent arteries and aneurysm neck, which were observed
at surgery. In both cases, the aneurysm walls were
wrapped with surgical gauze and cyanoacrylate glue
