Commentary on: 'could four dimensional contrast-enhanced ultrasounds replace computed tomography angiography during follow-up of fenestrated endografts? Results of a preliminary experience'

摘要

Fenestrated endovascular aneurysm repair (fEVAR) is a well-established alternative to open repair for patients with juxtarenal or short-neck AAAs. While computed tomography angiography (CTA) is considered the gold standard for surveillance, it bears the risk of contrast nephropathy and exposure to ionizing radiation, and is associated with high cost and resource allocation. Recommendations for standard EVAR have progressively changed to accept Duplex ultrasound (DUS)-based strategies, at least for patients at lower risk of complications. Currently, there are no specific recommendations from scientific societies regarding fEVAR surveillance, but expert opinion suggests close surveillance is necessary to insure lasting results.
