Ovarian vein thrombosis or thrombophlebitis of the ovarian vein is a serious condition.
Ovarian vein thrombosis is the result of a number of conditions such
as venous stasis and hypercoagulability, which are commonly present in
the recently postpartum patient
Ovarian vein thrombosis occurs in 0.02-0.18% of pregnancies and is
diagnosed on the right side in 80-90% of the affected postpartum
Complications include sepsis; and thrombosis of the inferior vena
cava and renal veins, which can lead to pulmonary embolism (25%); and
death (5% of complicated cases, with an estimated 18 deaths per million
The treatment is usualy anticoagulant therapy and
antibiotics, although in some cases a vena cava filter is placed to
prevent pulmonary embolism.
The ovarian veins form a plexus near the ovary within the broad
ligament and communicate with the uterine plexus. These veins ascend in
pairs in the retroperitoneum adjacent to the psoas muscle, then combine
to form a single vein before their termination. The right ovarian vein
terminates in the inferior vena cava; the left ovarian vein terminates
in the left renal vein.
