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.
在1076例颅内破裂动脉瘤（RA）患者中，948例经血管造影证实为RA，在908例最大直径小于25mm的RA中，162例RA直径<5mm，474例在5 - 10mm之间，272例在11 - 24mm之间。破裂后血管造影当天RA的平均直径在最初10天内无显著差异。在这种情况下，根据大小采用间接方法估计动脉瘤破裂风险时，我们还建议对于直径10mm及以下的未破裂动脉瘤，应认真考虑进行动脉瘤手术夹闭。
