The ovarian vein is also known as the female gonadal vein and acts as the female equivalent of the male's testicular vein. It is located in the ovary and comes in pairs. One of the veins is the right ovarian vein that starts from the pampiniform plexus at the hilum of the ovary and opens into the inferior vena cava.
While the right vein passes through the suspensory ligament of the ovary and joins with the inferior vena cava, the left joins with the left renal vein. The main function of this paired vein is to supply each ovary.
However, pathological studies show that the right ovarian vein syndrome occurs in pregnancy, experiencing right lumbar pains and nephritic colics. It is caused by a congenital malposition, pressing the right ureter on the external iliac artery. The diagnosis was conducted using intravenous urography and retrograde ureteral pyelography. Present treatment to overcome pain is through analgesics and it may be necessary to use a double-J catheter.
