Ovarian Vein Thrombosis: A Sequela of COVID-Associated Coagulopathy.

Coronavirus disease 2019 (COVID-19) causes endothelial damage, blood stasis, and an overall state of hypercoagulability. This makes COVID a huge risk factor for venous thromboembolism (VTE) and arterial thromboembolism (ATE). Twenty percent of COVID-19 patients suffer from coagulation abnormalities like pulmonary embolism, myocardial infarction, stroke, deep vein thrombosis, etc. Ovarian vein thrombosis (OVT) has been previously linked to post-partum period, pregnancy, hypercoagulable state, or malignancy. We analyzed PubMed and Google Scholar databases for research and publications regarding OVT in patients with COVID-19. The search yielded nine case reports. These case reports were found to implicate COVID-associated coagulopathy (CAC) as an additional risk factor for ovarian vein thrombosis (OVT). OVT most commonly presents with abdominal pain and fever, making it difficult to diagnose, owing to the similarity in presentation with multiple other pathologies. OVT can be diagnosed radiologically with ultrasound, magnetic resonance imaging (MRI) scan, or CT scan with IV contrast. CT has been used as the modality of choice for diagnosing OVT. Although rare, OVT can cause life-endangering complications by extension of thrombus into systemic veins or pulmonary artery embolization. Therefore, early diagnosis and treatment are vital. There is no official guideline for the treatment of OVT post-COVID. However, the literature supports the use of apixaban or enoxaparin/acenocoumarol.

Postpartum Ovarian Vein Thrombosis Due to COVID-19 in Pregnancy: A Case Report.

Ovarian vein thrombosis is a clinic condition that is generally seen in the postpartum period and can mimic acute appendicitis with acute abdomen. The incidence of occurrence has increased further in cases predisposing to thrombosis. Coronavirus disease 2019 (COVID-19) during pregnancy causes increased thromboembolic events. Here we examined a case of ovarian vein thrombosis after stopping enoxoparin in a postpartum patient who had COVID-19 during pregnancy.

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. LEARNING POINTS: 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.

Ovarian vein thrombosis as a first manifestation of COVID-19 infection.

Coronavirus disease 2019 (COVID-19) infection is associated with high risk of venous thromboembolic events mainly pulmonary embolism or deep venous thrombosis of the lower limbs. Ovarian vein thrombosis is a rare and serious condition usually seen in the immediate postpartum period and other conditions including pelvic inflammatory diseases, gynecological malignancies, hypercoagulable states, and few cases to date have reported ovarian vein thrombosis as a complication of COVID-19 infection. Patient with ovarian vein thrombosis usually presents with fever and lower abdominal pain that can mimic acute surgical abdomen and high index of suspicion is required for diagnosis. We report a case of a 41-year-old Asian female presented to our hospital with fever and acute lower abdominal pain. Laboratory findings show positive COVID-19 test and high D-dimer. Patient underwent computed tomography of the abdomen and pelvis and a confirmed diagnosis of right ovarian vein thrombosis was made. Patient was treated with anticoagulation and empirical antibiotics and her symptoms have significantly improved.

Isolated ovarian vein thrombosis in COVID-19 infection.

COVID-19 (coronavirus disease-19) is associated with an increased risk for thrombosis due to endothelial dysfunction and hyperactivation of the immune system induced by the virus. Most cases of venous thromboembolism associated with COVID-19 are either pulmonary emboli or deep vein thromboses. Ovarian vein thrombosis is a rare condition most commonly seen in the postpartum period. This report describes a case of COVID-19-associated ovarian vein thrombosis in a nonpregnant woman with no evidence of underlying inherited coagulopathy.

Ovarian vein thrombosis after coronavirus disease (COVID-19) mimicking acute abdomen: two case reports.

Coronavirus is a source of deep venous thrombosis (DVT) due to complications such as over-coagulation, blood stasis, and endothelial damage. Ovarian vein thrombosis (OVT) is a very serious and rare disease. In this study, we report tow rare case of women with coronavirus who were hospitalized with a right ovarian vein thrombosis mimicking acute abdomen who progressed well on anticoagulation. Our report adds further document in Side effects and rare localisation of obstruction of veins and arteries in patient with corona virus.

Right Ovarian Vein Thrombosis in the Setting of COVID-19 Infection.

Ovarian vein thrombosis is a rare condition associated with the postpartum state, pelvic disease, gynecological surgeries, and other thrombophilic states. We present the first reported case of right ovarian vein thrombosis (OVT) in the setting of Coronavirus disease 2019 (COVID-19) unrelated to pregnancy, pelvic disease, or surgery. This case highlights the breadth of the hypercoagulable state induced by COVID-19. We also put forward the use of novel oral anticoagulants in the case of OVT.
