Endovascular Repair of Abdominal Aortic Aneurysm Clinical Trial
Official title:
Computed Tomography Scan Versus Color Duplex Ultrasound for Surveillance of Endovascular Repair of Abdominal Aortic Aneurysm. A Prospective Multicenter Study
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.
