1 Intraoperative contrast-enhanced cone beam computed tomography to assess technical success during endovascular aneurysm repair  Christof Johannes Schulz, Matthias Schmitt, Dittmar Böckler, MD, PhD, Philipp Geisbüsch, MD  Journal of Vascular Surgery  Volume 64, Issue 3, Pages (September 2016) DOI: /j.jvs Copyright © 2016 Society for Vascular Surgery Terms and Conditions

2 Fig 1 Maximum intensity projection of a contrast-enhanced cone beam computed tomography (ceCBCT) image with a cylindrical field of view of 200 mm in diameter and 237 mm in height, which is usually large enough to evaluate endovascular aneurysm repair (EVAR), iliac side branch, and fenestrated and branched endograft procedures (excluding thoracic components).

4 Fig 3 Ability to evaluate stent graft position with regard to the lower renal artery on computed tomography angiography (CTA; left) and contrast-enhanced cone beam computed tomography (ceCBCT; right) in the same patient.

5 Fig 4 Digital subtraction angiography (DSA; left) shows good blood flow in the ipsilateral limb and impaired blood flow in the contralateral stent graft due to previously embolized hypogastric artery and sheath in place. On contrast-enhanced cone beam computed tomography (ceCBCT; right), a previously unseen thrombus was detected in the dorsal, ipsilateral stent graft and was successfully treated with thrombectomy.
