Is Circumaortic left renal vein rare?

Is Circumaortic left renal vein rare?

This is a relatively rare condition which can result in left renal hypertension (LRVH) syndrome which is otherwise called as anterior and posterior nutcracker syndromes. This venous anomaly results from the errors of embryological development.

What does the left renal vein supply?

The renal vein is an asymmetrically paired vessel that carries the deoxygenated blood from the kidney to the inferior vena cava….Renal vein.

Drains from Interlobar renal veins
Drainage area Kidneys, left testicle/ovary, left suprarenal gland, left portion of the diaphragm

Is Retroaortic left renal vein serious?

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.

What is the nutcracker effect?

Nutcracker phenomenon refers to compression of the left renal vein, most commonly between the aorta and the superior mesenteric artery, with impaired blood outflow often accompanied by distention of the distal portion of the vein.

Does nutcracker syndrome cause back pain?

The Nutcracker Syndrome is a rare and often unrecognized cause of chronic pelvic pain and left back pain. These symptoms are due to the left renal vein compression between the aorta and the superior mesenteric artery (anterior nutcracker) or between the aorta and the spine (posterior nutcracker).

What is the normal diameter of the left renal vein?

Normal Anatomy The left renal vein averages 8.5 cm in length and 1.5 to 2.5 cm in its greatest cephalocaudad diameter at its caval opening.

What is the main function of renal vein?

The main blood vessel that carries blood from the kidney and ureter to the inferior vena cava (a large vein that carries blood to the heart from the lower part of the body).

What happens if the renal artery is blocked?

The kidneys play an important role in regulating blood pressure by secreting a hormone called renin. If the renal arteries are narrowed or blocked, the kidneys cannot work effectively to control blood pressure. Persistent or severe high blood pressure is a common symptom of renal artery stenosis.

How common is a Retroaortic left 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.

What causes nutcracker disease?

It occurs when arteries, most often the abdomen’s aorta and superior mesenteric artery, squeeze the left renal (kidney) vein. It can cause many symptoms in both children and adults, such as flank pain and blood in the urine. Common treatments for nutcracker syndrome include stenting, surgery, and routine urine tests.

What causes renal nutcracker syndrome?

In nutcracker syndrome, symptoms are most often caused when the left renal vein coming from the left kidney becomes compressed and blood can’t flow normally through it. Instead, blood flows backwards into other veins and causes them to swell.

Can nutcracker syndrome make you tired?

This can result in elevated left renal vein pressure and reduced renal perfusion. Nutcracker syndrome, which refers to symptoms associated with the above phenomenon, usually presents with acute onset hematuria and abdominal pain, but more rarely, may present as chronic fatigue syndrome.

What happens if nutcracker syndrome goes untreated?

What is a normal velocity in the left renal vein?

The velocity of the left renal vein in the narrow portion was 116.3 cm/s; it was six times faster in the hilar portion. Fig. 2. The velocity of the left renal vein in the narrow portion was 116.3 cm/s; it was six times faster in the hilar portion.

What is the function of renal vein in kidney?

What blood does the renal vein carry?

Renal Veins carry filtered blood from the kidneys to the posterior vena cava. Renal Arteries carry unfiltered blood from the aorta to the kidneys. The arteries are obscured by the renal veins in this image; they are dorsal to the renal veins.

How do you unblock a renal artery?


  1. Renal angioplasty and stenting. In this procedure, doctors widen the narrowed renal artery and place a device (stent) inside your blood vessel that holds the walls of the vessel open and allows for better blood flow.
  2. Renal artery bypass surgery.

Can renal artery disease be cured?

Unlike treatment of fibromuscular dysplasia, cure of atheromatous renal artery stenosis by angioplasty alone is rare.

Is nutcracker syndrome surgery serious?

Conclusions: Open surgery, mostly LRV transposition, remains a safe and effective treatment of patients with NS.
