Is there a connection between size and risk of bleeding in unruptured intracranial aneurysms?

Of 1076 patients with intracranial ruptured aneurysms (RA), 948 had the RA verified by angiography, and of 908 RA with a maximum diameter less than 25 mm, 162 RA were < 5 mm, 474 were between 5-10 mm and 272 were between 11-24 mm. The average diameter of the RA according to the day of angiography after rupture did not differ significantly within the first 10 days. In these circumstances, using the indirect method for estimation of the risk of aneurysm rupture according to the size, we also recommend that unruptured aneurysms with a size 10 mm or less should be seriously considered for operative closure of the aneurysm.
