Application of Color-coded Quantitative Digital Subtraction Angiography in Evaluation of Prognosis After Endovascular Repairment of Abdominal Aortic Aneurysm
In Brief
An observational study for Endoleak and Aortic Aneurysm, Abdominal. Completed, enrolled 49 participants across 1 site.
Detailed 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.
