Accurate endoleak classification is essential following fenestrated endovascular aneurysm repair (f-EVAR). Both endoleak type and exact source of endoleak have implications upon the urgency and complexity of future management strategies. Herein we report on a patient with a documented endoleak post-f-EVAR, in which the source of blood flow into the aneurysm sac could not be determined using conventional computed tomographic angiography. Consequently, dynamic volumetric computed tomographic angiography (DV-CTA) was employed, which clearly illustrated the site of origin of the endoleak. DV-CTA enables accurate endoleak characterization following f-EVAR, with excellent conspicuity of the source of blood flow into the aneurysm sac.
准确的腔内渗漏分类对于腔内修复(f-EVAR)后至关重要。腔内渗漏的类型和确切来源对未来管理策略的紧迫性和复杂性都有影响。在此,我们报告了一位 f-EVAR 术后有明确腔内渗漏的患者,使用常规 CT 血管造影(CTA)无法确定血流进入动脉瘤囊的来源。因此,采用了动态容积 CT 血管造影(DV-CTA),清楚地显示了腔内渗漏的起源部位。DV-CTA 可在 f-EVAR 后准确进行腔内渗漏特征分析,对血流进入动脉瘤囊的来源具有极好的显影效果。
