Abstract

We describe how the presence of multiple renal arteries complicated the diagnosis of a major renal arterial injury following a lower thoracic penetrating injury. Incomplete assessment of the arteriographic evidence obtained during any invasive renal vascular investigation could result in a missed diagnosis.

Highlights

The identification of multiple renal arteries has traditionally been of major importance to the renal surgeon, for the pre-planning of renal transplantation
I As we show here this can present a pitfall for the interventional radiologist when trying to isolate a vascular abnormality such as a focal renal arterial injury
The definitive renal artery is not recognisable until the third month of fetal life. It arises from the most caudal of the three suprarenal arteries, all of which represent persistent mesonephric or lateral splanchnic arteries

Summary

Introduction

The identification of multiple renal arteries has traditionally been of major importance to the renal surgeon, for the pre-planning of renal transplantation. I As we show here this can present a pitfall for the interventional radiologist when trying to isolate a vascular abnormality such as a focal renal arterial injury. An abdominal CT scan allegedly showed a major renal injury with a perinephric haematoma.
