Description:
Minimal invasive vascular repair of abdominal aortic aneurysm was first reported in 1986. In the early 1990s endovascular aneurysm repair (EVAR) was developed for the treatment of patients unfit to undergo open surgical repair, but the procedure has since evolved into the primary method of treatment.

Stent graft devices have been designed for both abdominal and thoracic aneurysms (TEVAR) and have shown the early benefit of significantly reducing morbidity and mortality. However, in the longer term, there is loss of the early survival benefit with a cross-over at 4 years.

Anatomical features that may make standard EVAR difficult or impossible are poor quality necks including features such as inadequate neck diameter and length, or angulation shape and thrombus.

To overcome these morphological limitations of stent grafts, huge technical advancements have been made in terms of design, such as the introduction of fenestrated and branched devices. However, these special devices can take time to manufacture, which has prompted the development of innovations such as parallel-type grafts called chimneys and snorkels.

High-quality cross-sectional imaging, predominantly CT, is required for case planning to ensure the selection of the optimal device for patients.

Endoleaks are the most frequent complication of EVAR and the detection and characterisation of these endoleaks are vital in decision-making for further treatment.

EVAR and TEVAR have now replaced many of the open surgical repair programmes in the majority of hospitals with interventional and diagnostic radiology playing a major role in this vascular service.
