Intra-aortic CT Angiography (IA-CTA) is a relatively new technique that shows promise in efficient diagnosis and evaluation of the angioarchitecture of spinal dural arteriovenous fistulae(sdAVF). The authors document the first reported use of a 4D-CT and C-arm fluoroscope in a hybrid interventional suite to evaluate a sdAVF. Time resolved IA-CTA is clinically feasible in the evaluation of sdAVF, has higher temporal resolution as compared to standard IA-CTA and reduced contrast load, radiation dose and potential for procedural complications as compared to standard spinal angiography.

在混合血管造影套件中使用 4 维主动脉内脊髓 CT 血管造影评估脊髓硬膜瘘

主动脉内 CT 血管造影 (IA-CTA) 是一种相对较新的技术，有望有效诊断和评估硬脊膜动静脉瘘 (sdAVF) 的血管结构。作者首次报道了在混合介入套件中使用 4D-CT 和 C 臂荧光镜评估 sdAVF。时间分辨 IA-CTA 在 sdAVF 的评估中在临床上是可行的，与标准 IA-CTA 相比具有更高的时间分辨率，与标准脊柱血管造影相比，降低了对比剂负荷、辐射剂量和手术并发症的可能性。
