Ovarian vein thrombosis arises due to venous stasis and hyper-coagulability, which are commonly present in the recently postpartum patient. Other conditions that are associated with hyper-coagulability, such as recent surgery, malignancy and Crohn's disease also increase the patient's risk for ovarian vein thrombosis.
