[Abstract]:Objective: to analyze the related factors of intracranial aneurysm rupture and multislice spiral CT angiography (MSCTA) to predict the risk of aneurysm rupture. Methods: from April 2010 to February 2012, 48 patients with spontaneous subarachnoid hemorrhage and 18 patients without subarachnoid hemorrhage in the imaging center of the affiliated Hospital of Qinghai University were examined for intracranial aneurysms diagnosed by MSCTA, including 30 males. 36 cases were female (male: 0.83: 1), aged 30 to 72 years, with an average age of 52.76 鹵11.48 years. All patients underwent intracranial MSCTA scan with Philips Brillance16 slice and 256-slice spiral CT. The CT scan conditions were as follows: tube voltage 120 kV, tube current 300 Ma, slice thickness 0.8 mm, pitch 1, matrix 512 x 512, contrast media injection rate 4.0-4.2 ml / s, total CT scanning condition about 60-80ml(2)256 slice. For voltage 120kV, current 250 Ma, layer thickness 0.9 mm, pitch 0.5, pitch 0.825, matrix 512x512, injection speed 5.0 ml / s, total 40-50 ml, patient supine position, With both hands on both sides of the body, the right arm was followed by a needle injection, and the patient was told to relax, scan with a localization image, trace points to the aortic arch, set a trigger threshold of 120 HU. then select the aortic arch to the top of the skull as the scanning range. When the CT value of aortic arch reached 120HU, the reconstructed image was transferred to the Extended Brilliance Workspace2.0(16 row 4.5 / 256) workstation. The parameters, position and morphological features of aneurysm were measured on the post processing workstation. To compare their differences between ruptured and unruptured aneurysms. Results A total of 78 aneurysms were found in 66 patients with 1 / 66 cases, including 10 patients with 13 aneurysms in 256-layer, 30 unruptured aneurysms, 26 aneurysms with long diameter 10mm and 41 ruptured aneurysms with 10 mm long diameter aneurysms. Of these, 4 had 45 cysts between 40 and 65 years of age, 10 patients aged 40 to 65 years old, 11 patients aged 65 years old, 45 aneurysms located at the branches of blood vessels, 32 of them ruptured, 13 of them unruptured, and 33 of them were located at unbroken vessels, of which 16 were ruptured. There were significant differences in rupture of aneurysms between unruptured and unruptured aneurysms (X24.122 / P0.05). Through exclusion, 49 aneurysms were compared in tumor length, tumor neck length / neck length, tumor width / tumor neck width ratio. Ruptured and unruptured components were all aneurysm group (ALL) and aneurysm long diameter 10mm group, in ALL and long diameter 10mm: tumor length, There was no significant difference in short diameter and neck width between the two groups (P 0.05). The ratio of tumor length to neck width in ruptured group and unruptured group was 2.13 鹵0.83n 1.63 鹵0.51.The difference was statistically significant. The ratio of tumor width to neck width in ruptured group and unruptured group was 1.63 鹵0.66n1.29 鹵0.38, respectively. The ratio of tumor length to neck in ruptured group and unruptured group was 1.93 鹵0.59 鹵1.54 鹵0.31, there was statistical difference between the two groups, and the ratio of tumor width to neck width in ruptured group and unruptured group was 1.49 鹵0.51g / 1.23 鹵0.30.The difference between the two groups was statistically significant (t = 2.103, P 0.05), and the ratio between ruptured group and unruptured group was 1.49 鹵0.51g / 1.23 鹵0.30, and the ratio between ruptured group and unruptured group was 1.49 鹵0.51g / 1.23 鹵0.30. There was no statistical difference between the two groups. Conclusion: the location of aneurysm, the ratio of length to width of aneurysm and the ratio of width of artery to width of neck are the risk factors of possible rupture of aneurysm, and the difference is statistically significant.
