Objectives: The aim of this study was to evaluate the use of intraoperative DynaCT (IODCT) to asses for successful aneurysm exclusion during endovascular aneurysm repair (EVAR). Methods: Patients with EVAR who underwent IODCT were retrospectively evaluated. IODCT was performed with the 8sDSA protocol using 10s contrast injection and a 20s image acquisition time on Artis zeego with syngo DynaCT (Siemens Healthcare, Forchheim, Germany). Findings were compared with post-procedural multi slice detector CT (MDCT). 2D images and 3D post-processing reconstructions (Aquarius Workstation, TeraRecon, San Mateo, United States) were reviewed. Radiation dose was documented and contrast doses were compared between the two modalities. Statistical analysis was performed using a paired T-test. Results are expressed as mean standard error of the mean. Results: On table, completion IODCT was performed on 12 patients undergoing EVAR (one infrarenal, 2 juxtarenal, 9 thoracoabdominal) and 5 patients undergoing treatment for persistent endoleaks (2 type Ia, 3 type III). 12 cases did not show an endoleak on completion IODCT, and this was confirmed on follow-up MDCT. In 5 cases, IODCT detected an endoleak at the completion of the procedure (one type Ia, one type II and 3 type III endoleaks). Type I and III endoleaks were immediately treated and were not detected on follow-up MDCT. The type II endoleak was not visualized on follow-up MDCT. No branch occlusions, stent fractures or component separations were noted on IODCT, and this correlated with follow-up MDCT. Mean skin dose was 0.552Gy ( 0.0099) for IODCT and dose length product was 2.665 Gy*cm ( 0.200) for MDCT. Mean contrast dose was 40cc for IODCT compared to 105.29cc ( 26.248) for MDCT (p 0.001). Conclusions: IODCT is of sufficient quality to serve as an imaging modality for evaluating aneurysm exclusion in EVAR with lower contrast dose than MDCT. It could potentially replace the need for follow-up MDCT.
