Intra-operative DynaCT improves technical success of endovascular repair of abdominal aortic aneurysms

An 80-year-old man with a 65 mm infrarenal abdominal aortic aneurysms (AAA) with a 28 mm diameter concentric calcified neck (>40%) underwent an endovascular repair (EVR) (bifurcated Zenith Flex). Final angiography (a) indicated apparent exclusion of the endoleak. Evaluation with DynaCT, sagittal (b) and axial (c) reconstructions, demonstrated a significant anterior type 1a endoleak. Further balloon dilatation of the aortic neck resulted in complete correction of this proximal leak at a second multiplanar angiographic computed tomography (CT) (d, e).

A 73-year-old woman with a 55 mm abdominal aortic aneurysms (AAA) and 35 mm right common iliac artery (CIA) aneurysm underwent endovascular aneurysm repair (EVAR) with an aorto-uni-iliac Zenith device (12F) in the angiographic suite. DynaCT multiplanar rendering in coronal (b) sagittal (c) and axial (d, e) planes, showed an acute thrombus within the main body of the graft which had not been previously detected by completion angiography (a). On-table graft-thrombectomy via the indwelling common femoral artery (CFA) sheaths was performed successfully.
