Retroaortic left renal vein

Retroaortic left renal vein (RLRV) is an anatomical variant where the left renal vein is located between the aorta and the vertebra and drains into the inferior vena cava.

Its recognition is important in order to avoid complications during retroperitoneal surgery or interventional procedures 2.

Epidemiology

RLRV has an estimated prevalence of ~2% 3.

Clinical presentation

Urological symptoms can be caused by increased pressure in the renal vein resulting in venous hypertension. This is an atypical form of nutcracker syndrome. Patients can present with haematuria and recurrent left flank pain.
