In the majority of people, the right ovarian vein drains into the inferior vena cava and the left ovarian vein drains into the left renal vein, respectively (Fig. 1).  According to findings from a recent study, the ovarian veins are best seen at the level of the inferior mesenteric artery origin, which is where both veins are covered by retroperitoneal fat .

What does the ovarian vein connect to?
The ovarian veins are responsible for the appropriate flow of blood from the ovaries. A connection is made between the right ovarian vein and the inferior vena cava, whereas the connection is made between the left ovarian vein and the left renal vein.
Where does the ovarian vein branch from?
Opposite the suspensory ligament and the mesovarium, an ovarian plexus (pampiniform plexus) is formed by the veins of the ovary emerging from the ovary. Two veins arise from the plexus and ascend with the ovarian artery, where they normally unite into a single vein before terminating their journey through the body.
Where do the left ovarian vein and the right ovarian vein join the blood flow returning to the heart?
The right ovarian vein goes through the suspensory ligament of the ovary before joining the inferior vena cava in the majority of instances. In contrast to the right ovarian vein, the left ovarian vein frequently enters the left renal vein rather than the inferior vena cava.
What is the drainage of the left ovarian vein?
Pelvic Veins are the veins that go through the lower abdomen. Left ovarian vein feeds into left renal vein, whereas the right ovarian vein drains straight into the IVC (internal venous catheter) (the same is true for the testicular veins).
Is ovarian vein retroperitoneal?
Because ovarian vein leiomyosarcoma instances are uncommon, radiographic findings of ovarian vein leiomyosarcoma that have been previously described are few and far between. The lesions have only been described as a heterogeneous retroperitoneal mass with ipsilateral hydronephrosis by standard CT and excretory urography, and no more information has been obtained (2, 4, 5).
Where is the ovarian artery?
The anterolateral (or lateral) part of the abdominal aorta caudal to the origin of the renal arteries at the level of the L2 vertebra is where the ovarian arteries are most commonly seen to emerge. The ovarian arteries may emerge from the renal, suprarenal, inferior phrenic, superior mesenteric, lumbar, common iliac, or internal iliac arteries, among other sources of blood supply.
Where is the right gonadal vein?
The appearance of the right gonadal vein on computed tomography (CT) scans was investigated. In most cases, it is initially noticed 1 cm below the inferior vena cava (IVC) bifurcation and empties into the IVC laterally or anterolaterally 4 cm below the union of the right renal vein with the IVC.
Do ovarian veins have valves?
In order to return blood from the pelvis to the heart, the ovarian veins are designed to do so. A valve at the upper end of each vein helps to increase the amount of antegrade flow that gets to the heart. When there is valve failure or incompetence, the flow of blood is redirected into the pelvis, resulting in internal venous varicosities.
What membranes do ovaries form?
The surface of the ovaries is covered with a membrane composed of a lining of simple cuboidal-to-columnar shaped mesothelium, known as the germinal epithelium, which is located between the ovaries and the fallopian tubes.
Which of the following attach to the ovary?
Ligament of the Ovarian Reproductive Organs The suspensory ligament of the ovary (also known as the infundibular pelvic ligament) is a ligament that connects the ovary to the sidewall of the pelvis. The ovarian artery and vein, as well as the nerve supply to the ovary, are all included inside this bigger tissue.
Where does right suprarenal vein drain into?
The right suprarenal vein, which is located above the gonadal vein, finishes directly in the inferior vena cava, as does the right phrenic vein. During the passage of the diaphragm, two or three short hepatic trunks discharge into the inferior vena cava, which is a larger vein.
What is medial to the ovaries?
The ovary’s posterior side is exposed to the peritoneal cavity, which is a sign of pregnancy. Its medial border is connected to both the uterosacral fold and the body of the uterus by a fibrous band. The external iliac vein, ureter, and uterine tube form a shallow depression that is bordered by the uterine tube and the external iliac vein.
Which blood vessels supply the ovaries?
The ovarian artery is a straight branch of the abdominal aorta that supplies blood to the ovaries. The ovarian artery is a blood vessel that delivers oxygenated blood to the ovary, fallopian tube, and uterus during pregnancy.
What is ovarian vein syndrome?
A uncommon disorder characterized by varicose, dilated ovarian veins that produce persistent ureteral obstruction, ovarian vein syndrome (OVS) is caused by varicose, dilated ovarian veins. In addition to renal colic and nephroptosis, hypogastralgia and persistent low back pain1–5 are common clinical signs of OVS. In certain instances, renal function may be reduced.
What are ovaries made of?
Structure. The ovaries are covered on the outside by a layer of simple cuboidal epithelium known as germinal (ovarian) epithelium, which is a kind of epithelium with a cuboidal shape. This is actually the visceral peritoneum, which is the membrane that surrounds and protects the ovaries. The tunica albuginea, a thick connective tissue capsule, lies underneath this layer of connective tissue.
