During the fetal stage, several anastomoses between the ventral subcardinal and dorsal supracardinal veins cause a renal collar around the aorta. Usually, the dorsal branch degenerates, resulting in a single left renal vein. The existence of a circumaortic renal vein is explained by the persistence of both branches.

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 does the left renal vein do?
The right renal vein receives tributaries exclusively from the kidney, while the left renal vein receives several tributaries from other organs, including the left gonadal (ovarian/testicular) vein, left inferior phrenic vein and left adrenal veins. This article will discuss the anatomy and function of the renal vein.
What does Circumaortic left renal vein mean?
Circumaortic left renal vein, also known as circumaortic renal collar is an anomaly of left renal vein when a supernumerary or accessory left renal vein passes posterior to the aorta, apart from the normal renal vein passing anterior to the aorta.
Retroaortic Left Renal Vein
What level is the renal vein commonly?
L1-L2.
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 organs does the left renal vein drain?
Drains from Interlobar renal veins ------------- ---------------------------------------------------------------------------------- Drains to Vena cava inferior Drainage area Kidneys, left testicle/ovary, left suprarenal gland, left portion of the diaphragm.
Laparoscopic Resection Of A Hilar Pheochromocytoma In A Patient With Circum-Aortic Left Renal Vein
What can obstruct left renal vein?
Left renal vein obstruction, also known as Nutcracker phenomenonNutcracker phenomenonCompression of the left renal vein between the aorta and the superior mesenteric artery has been termed the nutcracker syndrome. Obstruction of left renal vein outflow results in venous hypertension with the formation of intra- and extrarenal collaterals and/or the development of gonadal vein reflux.https://pubmed.ncbi.nlm.nih.gov › ...Mesoaortic compression of the left renal vein (nutcracker syndrome) (NCP), occurs due to the external compression of the left renal vein (LRV) in between the angle formed by the origin of the superior mesenteric artery (SMAsuperior mesenteric artery (SMACast syndrome, commonly known as superior mesenteric artery (SMA) syndrome is a rare cause of small bowel obstruction caused by compression of third part of duodenum from narrowing of the angle between superior mesenteric artery and abdominal aorta resulting in symptoms of duodenal outflow obstruction.https://www.ncbi.nlm.nih.gov › pmc › articles › PMC6487991Cast syndrome - PMC - NCBI) from the aorta. The word "Nutcracker" was first used by Chait et al.
What does Circumaortic left renal vein?
Circumaortic left renal vein, also known as circumaortic renal collar is an anomaly of left renal vein when a supernumerary or accessory left renal vein passes posterior to the aorta, apart from the normal renal vein passing anterior to the aorta.

What is the left renal vein a branch of?
Renal Veins The left renal vein courses between the aorta and superior mesenteric arterysuperior mesenteric arteryIn human anatomy, the superior mesenteric artery (SMA) arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.https://en.wikipedia.org › wiki › Superior_mesenteric_arterySuperior mesenteric artery - Wikipedia to join the inferior vena cava. The left gonadal veingonadal veinIn medicine, gonadal vein refers to the blood vessel that carries blood away from the gonad (testis, ovary) toward the heart. These are different arteries in women and men, with the same embryological origin.https://en.wikipedia.org › wiki › Gonadal_veinGonadal vein - Wikipedia will drain into to left renal vein. The right gonadal vein drains directly into the inferior venal cava.
Is Circumaortic left renal vein normal?
Circumaortic left renal vein is an uncommon anomaly which can be associated with intermittent haematuria [4]. Angiogram reveals double left renal veins in the form of a venous collar. Computed tomography depicts the preaortic and retroaortic left renal veins clearly [3,5].
