【摘要】：目的探討256層螺旋CT技術(shù)在動脈瘤腔內(nèi)支架修復(fù)術(shù)(EVAR)后嚴(yán)重并發(fā)癥的診斷及隨訪中的應(yīng)用價(jià)值。方法分析40例EVAR患者術(shù)前及術(shù)后CTA的影像資料,術(shù)前CTA測量瘤頸、瘤體的大小,并評估不良近端錨定區(qū),術(shù)后CTA重點(diǎn)觀察有無內(nèi)漏、支架內(nèi)血栓形成及瘤腔大小的變化等。比較Ⅰ型內(nèi)漏與無Ⅰ型內(nèi)漏患者在不良近端錨定區(qū)的差異,并比較有無內(nèi)漏患者在瘤腔大小變化的差異。結(jié)果術(shù)后CTA共發(fā)現(xiàn)內(nèi)漏8例,其中Ⅰ型內(nèi)漏4例,Ⅱ型和Ⅲ型內(nèi)漏各2例,Ⅰ型內(nèi)漏均位于移植物近端,Ⅰ型內(nèi)漏患者中,75.0%(3/4)的患者存在不良近端錨定區(qū),明顯高于無Ⅰ型內(nèi)漏患者(11.1%,4/36),差異具有統(tǒng)計(jì)學(xué)意義(P=0.013)。2例(8.3%)出現(xiàn)移植物內(nèi)血栓形成。8例出現(xiàn)瘤體增大,其中6例(75.0%)為內(nèi)漏患者,2例(6.3%)為無內(nèi)漏患者,差異具有統(tǒng)計(jì)學(xué)意義(P=0.000)。結(jié)論 256層MSCTA可以對EVAR術(shù)后嚴(yán)重并發(fā)癥作出準(zhǔn)確診斷,并為進(jìn)一步治療提供影像學(xué)依據(jù),是首選的影像學(xué)檢查方法之一。
[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，
