Ovarian Vein Thrombosis in a Non-Puerperal Patient

Ovarian vein thrombosis (OVT) is a relatively rare, but serious disease more commonly seen in puerperal patients. In the postpartum period, there is an unequal incidence of OVT in women with vaginal delivery (0.18%) and caesarean section (2.0%). OVT is usually associated with other conditions like pelvic inflammatory disease, malignant tumours, sepsis, enteritis, and recent pelvic or abdominal surgery. The incidence of idiopathic OVT is extremely rare and only a few cases have been reported to date in healthy patients with unknown aetiology. Patients with OVT present with abdominal pain, nausea, vomiting, fever or abdominal mass. Complications of OVT include pulmonary embolism, ovarian infarction, sepsis and death. CT scanning of the abdomen provides reliable evidence for the diagnosis of idiopathic OVT. Thrombus in most patients with idiopathic OVT is located in the right ovarian vein. This may be due to the longer length of the right ovarian vein, right shift of the uterus and relative insufficiency of the right ovarian vein valve. Treatment of OVT includes systemic anticoagulation which will achieve resolution of symptoms and prevent life-threatening complications. Our case report documents a non-puerperal patient who underwent hysterectomy a year before presenting to the ED with complaints of diarrhoea and found to have OVT on a CT scan. Our case brings attention to the fact that OVT can occur outside the puerperium and might present as a rare complication of minimally invasive surgeries for endometrial cancer. Furthermore, we posit that OVT in the non-puerperal patient may be a separate clinical entity.

Ovarian vein thrombosis (OVT) can occur outside the puerperium and might present as a rare complication of minimally invasive surgeries.OVT should be included in the differential diagnosis of a non-puerperal postoperative woman presenting with vague abdominal symptoms.Duration of anti-coagulation varies from case to case. More research is needed to determine its exact duration.
