What is thrombosis of ovarian vein?

Discussion. Ovarian vein thrombosis (OVT), a known complication during pregnancy and postpartum, often presents as fever and lower abdominal pain within weeks after delivery. Symptomatic postpartum OVT complicates 0.01% to 0.05% of deliveries,2,3 more often after cesarean delivery.

How do you treat ovarian vein thrombosis?

There are currently no treatment guidelines defined for OVT, but prior treatment recommendations for symptomatic and asymptomatic OVT have included antibiotics, hysterectomy, thrombectomy, ovarian vein ligation, ovarian vein excision, IVC ligation, and IVC filter placement.

What causes blood clot in ovaries?

OVT is a rare condition that has been associated with the postpartum period, malignancy, abdominal and pelvic surgery, pelvic inflammatory disease, and inflammatory bowel disease. It has been reported to occur in 0.05% to 0.16% of pregnancies, mainly in the postpartum period, and up to 2% of Caesarean sections.

Is ovarian vein thrombosis life-threatening?

Ovarian vein thrombosis (OVT) is an extremely rare but life-threatening complication of the postpartum period.

Is ovarian vein thrombosis life threatening?

Where does the right ovarian vein drain into?

inferior vena cava
The right ovarian vein drains into the inferior vena cava and the left ovarian vein into the left renal vein in most individuals (Fig. 1). A recent study noted that the ovarian veins are best visualized at the level of the inferior mesenteric artery origin, where both veins are surrounded by retroperi- toneal fat [1].

What does a pelvic blood clot feel like?

Symptoms include pelvic pain, back pain, fever, vomiting, nausea, chills, and at times, a ropelike mass that can be felt in the abdomen.

Where is the ovarian vein located?

The ovarian vein, the female gonadal vein, carries deoxygenated blood from its corresponding ovary to inferior vena cava or one of its tributaries. It is the female equivalent of the testicular vein, and is the venous counterpart of the ovarian artery. It can be found in the suspensory ligament of the ovary.

How serious is a pelvic blood clot?

Pelvic vein thrombosis occurs when a blood clot occurs that obstructs the blood flow in one of your pelvic veins. Blood clots in the pelvic veins can be very serious because they not only have the potential to cause localized problems, they may also break loose and travel to the lungs.

What is the function of the ovarian vein?

The ovarian vein, the female gonadal vein, carries deoxygenated blood from its corresponding ovary to inferior vena cava or one of its tributaries. It is the female equivalent of the testicular vein, and is the venous counterpart of the ovarian artery.

What causes ovarian vein syndrome?

According to Clark, OVS is caused by the compression of the ureter by dilated ovarian veins induced by pelvic congestion or an enlarged uterus during pregnancy.

Where does right ovarian vein drain?

The right ovarian vein usually drains into the inferior vena cava (IVC) whereas the left ovarian vein drains into the left renal vein in most individuals [1,10,11].

What are the symptoms of ovarian vein syndrome?

Symptoms arising Ovarian Vein Syndrome include pelvic pain, pain during or after intercourse, feeling of fullness in the legs, stress incontinence and worsening of symptoms associated with irritable bowel syndrome (IBS).

How common is ovarian vein syndrome?

In medicine, ovarian vein syndrome is a rare (possibly not uncommon, certainly under-diagnosed) condition in which a dilated ovarian vein compresses the ureter (the tube that brings the urine from the kidney to the bladder). This causes chronic or colicky abdominal pain, back pain and/or pelvic pain.

How is thrombosis caused?

Arterial thrombosismay be caused by a hardening of the arteries, called arteriosclerosis. This happens when fatty or calcium deposits cause artery walls to thicken. This can lead to a buildup of fatty material (called plaque) in the artery walls. This plaque can suddenly burst (rupture), followed by a blood clot.

Which CT findings are characteristic of ovarian vein thrombosis?

On CT, differentiation of the thrombosed ovarian vein from the appendix can be difficult; visualization of a tubular retroperitoneal mass with central low attenuation extending cephalic to the inferior vena cava is characteristic of ovarian vein thrombosis.

What is ovarian vein thrombosis?

Ovarian vein thrombosis is a rare complication which arises classically in the post-partum. Ovarian vein is the commonest vein involved in puerperal pelvic thrombophlebitis [1].

How is ovarian vein thrombosis diagnosed during pregnancy?

Diagnosis can be made with confidence using ultrasound, computed tomography or magnetic resonance imaging. Treatment of ovarian vein thrombosis is particularly important in the post-partum patients, with anticoagulation therapy being the current recommendation.

Should ovarian vein thrombosis be included in the differential diagnoses?

Although ovarian vein thrombosis is uncommon, it should be included in the differential diagnosis for postoperative women presenting with vague abdominal symptoms given the potentially fatal outcome associated with this condition.
