Details and patient eligibility

About

Cumulative radiation dose, cost, contrast induced nephrotoxicity and increased demand for computed tomography aortography (CTA) suggest that duplex ultrasonoraphy (DU) may be an alternative to CTA-based surveillance. The investigators compared CTA with DU during endovascular aneurysm repair (EVAR) follow-up.

Patients undergoing EVAR have radiological follow-up data entered in a prospectively multicenter database. The gold standard test for endoleak detection was CTA. DU interpretation was performed independently of CTA and vice versa.
