Although the risk is lower with EVAR, this comes with an increased likelihood of later complications requiring further corrective intervention. This is reported to be up to 20% at 5 years. For this reason, patients having undergone EVAR require close surveillance with CT or ultrasound.
Other complications may include compromised circulation to the legs requiring corrective surgery, chest infection, kidney failure requiring temporary dialysis, and others which require bespoke discussion.
Ultimately, the decision to proceed with surgery to AAA is only justified if the risk of rupture (If AAA left untreated) outweighs all the complications mentioned, in carefully selected patients. For this reason, having a full understanding between the patient and their Vascular Surgeons is vital in order to achieve best outcome.
