【摘要】：目的探讨256层螺旋CT技术在动脉瘤腔内支架修复术(EVAR)后严重并发症的诊断及随访中的应用价值。方法分析40例EVAR患者术前及术后CTA的影像资料,术前CTA测量瘤颈、瘤体的大小,并评估不良近端锚定区,术后CTA重点观察有无内漏、支架内血栓形成及瘤腔大小的变化等。比较Ⅰ型内漏与无Ⅰ型内漏患者在不良近端锚定区的差异,并比较有无内漏患者在瘤腔大小变化的差异。结果术后CTA共发现内漏8例,其中Ⅰ型内漏4例,Ⅱ型和Ⅲ型内漏各2例,Ⅰ型内漏均位于移植物近端,Ⅰ型内漏患者中,75.0%(3/4)的患者存在不良近端锚定区,明显高于无Ⅰ型内漏患者(11.1%,4/36),差异具有统计学意义(P=0.013)。2例(8.3%)出现移植物内血栓形成。8例出现瘤体增大,其中6例(75.0%)为内漏患者,2例(6.3%)为无内漏患者,差异具有统计学意义(P=0.000)。结论 256层MSCTA可以对EVAR术后严重并发症作出准确诊断,并为进一步治疗提供影像学依据,是首选的影像学检查方法之一。
[Abstract]:Objective to evaluate the value of 256-slice spiral CT in the diagnosis and follow-up of severe complications after intracavitary stent repair of aneurysms. Methods the imaging data of 40 patients with EVAR before and after operation were analyzed, and the size of tumor neck and tumor were measured by CTA before and after operation. After operation, CTA was used to observe whether there were internal leakage, thrombosis in stent and the change of tumor cavity size. The difference between patients with type 鈪，
