Abstract
Objective To investigate the CT signs of small intracranial aneurysm and the application value of multi-slice spiral CT angiography (MSCTA) before and after clipping surgery and in follow-up.Methods MSCTA imaging data of 81 patients with highly suspected small intracranial aneurysms from March 2013 to March 2015 were analyzed retrospectively.The confirmed patients underwent clipping surgery of small intracranial aneurysms.The imaging findings before and after clipping surgery were analyzed and compared with those by DSA and what observed during surgery.Results The relative accuracy,sensitivity and specificity of MSCTA over DSA and surgical diagnosis were 93.83％,93.75％ and 94.12％respectively,and MSCTA gained high relative consistency over DSA and surgical diagnosis (Kappa=0.825).The accuracy of MSCTA for diagnosing small intracranial aneurysm was not significantly different from those by DSA and surgical diagnosis.MSCT plain scan mainly showed subarachnoid or intracranial hemorrhage,and found 71 rhomboic or saccular aneurysms in 60 patients before operation.Totally 64 patients went through clipping surgery,60 ones had satisfactory results in the reexamination by MSCTA 2 weeks after surgery,and there were no abnormality found in 36 patients in 6 to 12-month follow-up.Conclusion MSCTA can provide abundant information for clipping surgery of small intracranial aneurysms,and can be used as the preferred imaging method for postoperative evaluation and follow-up.关键词
