Remnant aortic neck after open AAA repair and novel AAA formation: a practice to be avoided
A remaining potent part of the infrarenal aorta after aneurysmectomy for AAA, poses a potential risk for de novo AAA development, and therefore is good to be avoided. An interesting case of an open repair for a pararenal AAA is presented, which was developed 13 years after successful AAA open repair. An important feature of this patient’s anatomy was the low origin of the left (lowest) renal artery. Due to aneurysmal disease progression and proximal neck dilatation, the patient needed to be re-operated, because a new aneurysm (this time, a pararenal AAA) had developed above the old proximal anastomosis, encompassing the origin of the left renal artery.
