There are two renal veins, a left and a right. They branch off the inferior vena cava and drain oxygen-depleted blood from the kidneys. As they enter the kidneys, each vein separates into two parts. The posterior veins assist in draining the back section of each kidney, while the anterior veins assist the front part.
Where do the gonadal veins branch off of?
The ovarian veins are similar to the testicular veins as they originate from the plexus in the broad ligament near the ovary and fallopian tube, then left ovarian vein joins the left renal vein and right one drains the IVC [4] . Variations of gonadal veins may reflect complicated embryogenesis in this area.
What structures do the gonadal veins drain?
The gonadal veins are the veins which drain the testes in men (testicular vein) and the ovaries (ovarian vein) in women. The left gonadal vein drains into the left renal vein, which then drains into the inferior vena cava. The right gonadal vein however, drains directly into the inferior vena cava.
Where is gonadal?
They are located in the pelvis, one on each side of the uterus, and they have two functions: They produce eggs and female hormones.

The gonadal arteries are paired vessels that usually originate from the abdominal aorta at the level of second lumbar vertebra. In 5-20% of cases, the gonadal artery has a high origin (superior to L2) and in 5-6% of cases it originates from the main or accessory renal artery.

Article first time published onWhat is gonadal vein reflux?
When the ovarian vein dilates, the valves do not close properly. This results in a backward flow of blood, also known as “reflux.” When this occurs, there is pooling of blood within the pelvis. This, in turn, leads to pelvic varicose veins and clinical symptoms of heaviness and pain.
What is a dilated gonadal vein?
Dilated ovarian and/or pelvic veins causes venous incompetence and reversed flow in the ovarian veins. This in turn causes pelvic pain or aching around the pelvis and lower abdomen and can extend into the back. Because these veins are internal, the condition is often under-recognised.

Which vein drains blood from the distal half of the large intestine?
The splenic vein drains the stomach, the superior mesenteric vein drains the upper small intestine, while the inferior mesenteric vein drains the distal portions of the colon. These three tributaries drain into the portal vein, which supplies the liver whose venous effluent is delivered back to the heart [2,4,5].
What drains into the superior mesenteric vein?
The main function of the superior mesenteric vein is to drain the blood from the distal portion of the gastrointestinal tract. Specifically, it drains the small intestine, caecum, ascending and transverse parts of the colon, and distal parts of the stomach and greater omentum.
What does the phrenic vein drain?
