What does the left renal vein do?
The left renal vein traverses behind the splenic vein and body of the pancreas before it crosses in front of the aorta near its termination in the inferior vena cava. The left renal vein collects the flow from the left ureteral, gonadal, adrenal, and inferior phrenic veins.
What is the anatomical location of the renal vein?
Renal veins lie in front of the corresponding renal artery; the right renal vein receives tributaries exclusively from the kidney, while the left receives blood from a number of other organs as well. The right suprarenal vein terminates directly in the inferior vena cava as…
What causes compression of the left renal vein?
Nutcracker syndrome is a rare vein compression disorder. 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.
What does renal vein mean?
Medical Definition of renal vein : a short thick vein that is formed in each kidney by the convergence of the interlobar veins, leaves the kidney through the hilum, and empties into the inferior vena cava.
Which organs does the left renal vein carry blood from?
The renal vein is an asymmetrically paired vessel that carries the deoxygenated blood from the kidney to the inferior vena cava. Both left and right veins run anterior to their corresponding renal arteries.
What type of blood does 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.
What organs does the left renal vein drain?
The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava. They carry the blood filtered by the kidney….

What is left renal artery?
The renal arteries are large blood vessels that carry blood from your heart to your kidneys. Renal is another word for kidney. You have two renal arteries. The right renal artery supplies blood to the right kidney, while the left artery sends blood to the left kidney.
What is compression of left renal vein?
Abstract. Compression of the left renal vein (LRV) between the superior mesenteric artery and the aorta has been termed the nutcracker syndrome.
What does renal vein kidney do?
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 is the difference between renal artery and renal vein?
Where is the retroaortic left renal vein located?
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.
What are the different types of renal venous anomalies?
There are several variations in renal venous anatomy. Some of these are specific to the left renal vein. Left renal vein anomalies are generally classified into four types 2: type I the ventral pre-aortic limb of the left renal vein is obliterated, but the dorsal retro-aortic limb persists and joins the IVC in the normal position.
What causes pain in the left renal vein?
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 hematuria and recurrent left flank pain.
Where does the rlrv join the IVC?
Left renal vein abnormalities were categorized into four types. Type I, II, III, and IV of RLRV join the IVC in the orthotopic position, join the IVC at level L4-5, join at the circumaortic or collar left renal vein, or join the left common iliac vein, respectively (Fig. 1, ,2)2) [6,7].
