What does this research mean for the field?

Left renal vein pseudo-fenestration is a distinct anatomical variant formed by the convergence of two distinct hilar venous trunks, which differs from true fenestration and requires accurate preoperative recognition to prevent iatrogenic surgical injury. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To describe an uncommon left renal vein pseudo-fenestration and delineate its embryological origin and surgical significance.

Implication

Case report demonstrates left renal vein pseudo-fenestration in a 68-year-old female, highlighting the importance of vascular mapping to avoid iatrogenic injury during retroperitoneal surgery.

Key Points

To describe an uncommon left renal vein pseudo-fenestration and delineate its embryological origin and surgical significance.
Assessed abdominal vascular anatomy in a 68-year-old female using contrast-enhanced multidetector computed tomography.
Evaluated tributary drainage patterns using multiplanar and three-dimensional image reconstructions.
Demonstrated a pseudo-fenestration arising from the confluence of two distinct hilar venous trunks rather than the bifurcation and reunification of a single trunk.
Identified selective drainage of the left suprarenal vein into the superior limb and the left gonadal vein into the inferior limb, consistent with asymmetric embryological fusion of the cardinal venous system.
