The prevalence of the fenestrated left renal vein.

ABSTRACT:

Purpose

The left renal vein (LRV) is typically a single preaortic vein. The discovery of fenestrated LRVs (FLRVs), a rare occurrence previously reported only twice, has piqued our interest. We aimed to determine the prevalence of such variants using an angioCT batch.

Methods

We meticulously studied archived angioCT files of 95 men and 55 women. The morphology of the LRVs was carefully checked on planar sections and by three-dimensional volume renderings, ensuring the accuracy of our findings.

Results

In 3.34% of cases, four males and one female were found FLRVs. Their posterior projections on the aorta were variable. The FLRVs were either partly preaortic, immediately to the left side of the aorta, or at a distance to the left side of the aorta. There were three true
