Outcomes of fenestrated-branched endovascular aortic repair in patients with a solitary functional kidney

Mid-term follow-up of renal artery reimplant in open surgical repair for abdominal aortic aneurysm with a crossed-fused renal ectopia

Crossed-fused renal ectopia is an uncommon congenital condition, and its association with abdominal aortic aneurysm can present a complex surgical scenario. We present a case of a 71-year-old male with abdominal aortic aneurysm and crossed-fused renal ectopia who underwent open surgical repair with renal artery reimplantation, using mannitol infusion and cold crystalloid perfusion for renal protection. Postoperatively, after transient creatinine rise, renal function normalized without dialysis. At 24 months follow-up, the reimplanted renal artery remains patent with normal renal function. This case illustrates open surgical repair's effectiveness in addressing complex vascular anatomy, ensuring durable outcomes, and preserving vessel patency and renal function.

Postoperative management in patients with complex aortic aneurysms

Patients with complex aortic aneurysms (CAA) are often high risk due to advanced age and widespread atherosclerosis affecting numerous vascular territories. Therefore, a thorough perioperative evaluation is needed prior to performing in any type of aortic repair, regardless of whether an endovascular or open surgical approach is selected. Because these operations are technically demanding and often result in end organ ischemia, it is not surprising that complex aortic repair carries significant risk of morbidity and mortality. Disabling complications such as dialysis, major stroke and paraplegia constitute the main limitation of complex aortic repair. The aim of this article was to review postoperative management to mitigate complications after CAA repair.
