CQDSA in Evaluation of Prognosis After EVAR

NCT02016131 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 49

Summary

Re-hospitalization or re-intervention is sometimes necessary to treat type I and type III endoleaks after EVAR for its persistent increasing of pressure in aneurysm lumen. Color-coded quantitative digital subtraction angiography (CQDSA) provides an easy and quick way to post-process the traditional digital subtraction angiography (DSA) which converts the peak time of the maximal contrast medium intensity into a single polychromatic image. With the help of CQDSA, a quantitative evaluation of the endoleak hemodynamics and a risk analysis of the type I or type III endoleak could be performed during the EVAR procedure. This approach may offer an objective assessment of the needs for immediate re-intervention, conservative therapy or treatment endpoint in the future.
