Abstract:
Objective To evaluate the size,aspect ratio and configuration in ruptured aneurysms. Methods Three-dimensional CT angiogram of 61 confirmed ruptured saccular aneurysms were analyzed.The maximum diameter and aspect ratio were measured,and the configuration of the aneurysms were observed. Results The average maximum diameter was 8.54 mm,and 78.8% of the aneurysms were less than 10 mm in maximum diameter.The average aspect ratio was 2.15,and more than 65% of the aneurysms had an aspect ratio over 1.6.45.9% of the aneurysms harbored a bleb or were multi-lobular in shape. Conclusion Aneurysms less than 10 mm in maximum diameter are also easy to rupture.More than 60% of the ruptured aneurysms had an aspect ratio over 1.6.Bleb and multi-lobular change are common in ruptured aneurysms.
