title: Evaluation of intra-aortic CT angiography performances for the visualisation of spinal vascular malformations' angioarchitecture.
abstract: OBJECTIVE
  To evaluate the performances of the CT-angiography by direct intra-aortic contrast media injection (IA-CTA) for spinal vascular malformations (SVMs)' imaging.
  
  
  METHODS
  Thirteen patients (8 males, 5 females, mean age: 56 y) with suspected SVM underwent IA-CTAs by direct intra-aortic iodinated contrast media injection (5 cc/s; 100 cc) via an arterial femoral or humeral access. Two independent observers evaluated the angioarchitecture of the SVMs and the visualisation of both the Adamkiewicz artery and the anterior spinal artery. Then a consensus was obtained between the 2 reviewers; the results of the IA-CTA were finally compared with those of the full spinal DSA evaluated in consensus.
  
  
  RESULTS
  The IA-CTA was feasible in all cases and depicted the SVM in all except one case (92 %). Interrater agreement was good for the location of the SVMs' level. Intermodality (IA-CTA/DSA) agreement was excellent for the level and side of the shunt point, as well as for the SVM subtype evaluation. In 77 % of the cases, the Adamkiewicz artery was satisfactorily seen at the same time on IA-CTA.
  
  
  CONCLUSIONS
  IA-CTA is a new technique that seems helpful to reach a better understanding of SMVs and may help to tailor more precisely their treatment.
  
  
  CONCLUSIONS
  • IA-CTA is an accurate technique for the SVMs' angioarchitecture analysis • IA-CTA can locate, at the same time, the Adamkiewicz artery (AKA) • IA-CTA may be helpful in elderly patients with troublesome vasculature.
