Annals of Vascular Surgery 2021; 77: 349.e345-349.e318.


Aims
This paper reports a case series of kidney autotransplantation (KAT) for renal artery aneurysm (RAA). It also includes a systematic review evaluating outcomes of KAT for RAA.

Interventions
In the systematic review, electronic databases including Medline Ovid, Embase, Cochrane CENTRAL , Web of science and Google scholar were searched. Studies were screened for eligibility by two independent reviewers. The methodological quality of the included studies were also assessed.

Participants
102 studies were inclded in the systematic review.

Outcomes
The main outcomes of interest included postoperative complications, graft loss, and postoperative hospital stay.

Follow-up
N/A

CET Conclusions
This paper is based around a case series of renal auto-transplantation for a rare indication- renal artery aneurysm. In addition, the paper includes a systematic review. The review searched multiple databases, and abstracts were screened in duplicate although it does not appear that data was extracted in duplicate. There is a formal quality assessment of the 102 papers included (66% of which were single case reports). The authors summarise the demographics of included patients and the surgical approaches used. Overall patient and graft outcomes seem acceptable, but a minority of papers reported outcomes beyond 1 year. It would have been useful to see a comparison with endovascular techniques, where this approach could have been technically feasible.
