What does Retroaortic left renal vein mean?
Retroaortic left renal vein (RLRV) is a normal 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.
Does Retroaortic left renal vein cause pain?
A retroaortic left renal vein is usually asymptomatic; however, patients can present with haematuria, flank pain, scrotal varicocele and pelvic congestion due to the nutcracker syndrome.
Is Retroaortic left renal vein rare?
A left renal vein passing behind the abdominal aorta is termed a retroaortic left renal vein (RLRV), and this anomaly is a relatively uncommon condition.
How common is Retroaortic renal vein?
A retroaortic left renal vein (RLRV) is located between the aorta and the lumbar vertebrae and drains into the inferior vena cava (IVC) or left common iliac vein [3]. The incidence of RLRV has been reported from 0.5% to 3.6% [3], [4], [5], [6].
What happens if you don’t treat nutcracker syndrome?
The risks to not treating Nutcracker Syndrome are progressive kidney damage and the risk of complete occlusion of the kidney vein by a clot. Once this happens, the prognosis becomes much worse, and the chance of complete resolution of the problem is far less.
Can you live with nutcracker syndrome?
Nutcracker syndrome may cause mild or no symptoms, and it may resolve on its own (especially in children). However, it can sometimes harm your body over time if untreated. Possible complications of unmanaged nutcracker syndrome include: Blood clots in your renal vein.
What happens if nutcracker syndrome goes untreated?
However, it can sometimes harm your body over time if untreated. Possible complications of unmanaged nutcracker syndrome include: Blood clots in your renal vein. Kidney damage caused by increased pressure in your renal veins over time.
What causes left renal vein compression?
Most often caused by compression by the aorta and superior mesenteric artery, nutcracker syndrome can be more prevalent with significant lack of abdominal fat, during growth in children and adolescents, and with spine conditions such as lordosis of the lumbar spine.
Does nutcracker syndrome cause headaches?
Nutcracker syndrome usually presents with hematuria, flank pain, varicocele, orthostatic proteinuria, or orthostatic intolerance. Headaches are known to occur with Nutcracker syndrome (2), but neither syndrome has an established association with new daily persistent headache (NDPH).
What kind of doctor treats nutcracker syndrome?
Your vascular surgeon will discuss treatment options for your particular anatomy and their risks and benefits so you can make an informed decision. If patients are suffering from Nutcracker Syndrome, it is important that they locate an acquainted vascular surgeon to carry out the treatment of Nutcracker Syndrome.
What is the clinical importance of retroaortic left renal vein (rlrv)?
Purpose A retroaortic left renal vein (RLRV) is located between the aorta and the vertebra and drains into the inferior vena cava. Urological symptoms can be caused by increased pressure in the renal vein. To evaluate the clinical importance of RLRV, we reviewed patients’ medical records and radiologic findings. Materials and Methods
Can a retroaortic vein cause varicocele?
In addition, compression of a retroaortic left renal vein can also result in varicocele formation and ureteropelvic junction obstruction [20]. Congenital renal vascular variations can cause renal vascular congestion, that clinically manifests as hematuria, left flank pain and pelvic congestion [5, 13, 21-24].
What is a retro aortic renal vein?
A retro aortic renal vein is an anatomical variation in which the left renal vein passes behind the aorta. Anatomic issue: The left renal vein normally runs over or anterior to the aorta. In some patients the left renal vein congenitally courses behind the aorta.
What is the posterior Nutcracker phenomenon in left renal vein?
Retroaortic left renal veins can be compressed between the aorta and the vertebra, referred to as the “posterior nutcracker phenomenon”. The compression can elevate pressure within the left renal vein, leading to hematuria, and resultant congestion of the left kidney [7, 17- 19].
