Reconstruction of the accessory renal artery with autogenous vessels in aortic hybrid surgery: A case report.

ABSTRACT

OBJECTIVE: Accessory renal artery (ARA) is a common variant of renal vessels. Currently, there are some controversies about reconstruction strategy and few cases reported in the literature. Individualized treatment should be carried out according to preoperative renal function evaluation and technical level. METHODS: In this paper, a 50-year-old male patient was reported, who developed a dissecting aneurysm after thoracic endovascular aortic repair (TEVAR) and needed further intervention. Imaging showed that the left kidney was supplied by bilateral renal artery (false lumens), and there were left renal malperfusion complicated with abnormal renal function. RESULTS: Autologous blood vessels were used to successfully reconstruct ARA with during hybrid surgery. Renal perfusion and renal function recovered rapidly after operation. There was no abnormality in renal indexes after 3 months follow-up. CONCLUSION: It is beneficial and necessary to reconstruct ARA for patients with renal malperfusion or abnormal renal function before operation.
