Comparison of MRA and DSA in examination after intracranial aneurysm surgery
摘要
Abstract
Objective To compare the clinical value of digital subtraction angiography (DSA) and magnetic resonance angiography (MRA) in grading intracranial aneurysm postoperation. Methods The study recruitcd 72 patients after surgery for intracranial aneurysm. The grading of intracranial aneurysm postoperation and follow-up for three months was performed by DSA and MRA. Results Grading by DSA and TOF-MRA of intracranial aneurysm after follow-up for three months did not differ significantly ( χ2 =0. 95, P>0.05). The sensitivity of Class I intracranial aneurysm postoperation detected by MRA and DSA was 94. 3% and 97. 1% while the specificity was 91.9% and 89.2%, respectively, without significant difference (P>0.05). The grading of intracranial aneurysm postoperation and follow-up increased with the incidence of high blood pressure ( χ2=7.82, P<0.05), showing a positive correlation (r = 0. 47, P<0. 05). MRA and DSA did not differ significantly in detecting the average number of cerebrovascular branches in patients with intracranial aneurysm (P>0.05). Conclusion MRA and DSA can be used in follow-up of intracranial aneurysm surgery. The former is a non-invasive means of examination, thus deserving wide clinical application.关键词
