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

Effects of COVID-19 Infection and Vaccination on the Female Reproductive System: A Narrative Review

Several studies and research papers have been published to elucidate and understand the mechanism of the coronavirus disease 2019 (COVID-19) pandemic and its long-term effects on the human body. COVID-19 affects a number of organs, including the female reproductive system. However, less attention has been given to the effects of COVID-19 on the female reproductive system due to their low morbidity. The results of studies investigating the relationship between COVID-19 infection and ovarian function in women of reproductive age have shown the harmless involvement of COVID-19 infection. Several studies have reported the involvement of COVID-19 infection in oocyte quality, ovarian function, and dysfunctions in the uterine endometrium and the menstrual cycle. The findings of these studies indicate that COVID-19 infection negatively affects the follicular microenvironment and dysregulate ovarian function. Although the COVID-19 pandemic and female reproductive health have been studied in humans and animals, very few studies have examined how COVID-19 affects the female reproductive system. The objective of this review is to summarize the current literature and categorize the effects of COVID-19 on the female reproductive system, including the ovaries, uterus, and hormonal profiles. The effects on oocyte maturation, oxidative stress, which causes chromosomal instability and apoptosis in ovaries, in vitro fertilization cycle, high-quality embryos, premature ovarian insufficiency, ovarian vein thrombosis, hypercoagulable state, women’s menstrual cycle, the hypothalamus-pituitary-ovary axis, and sex hormones, including estrogen, progesterone, and the anti-Müllerian hormone, are discussed in particular.

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.

Diagnostic laparoscopy and oophorectomy for ovarian vein thrombosis in a patient with COVID-19: a surgical case report and literature review

Ovarian vein thrombosis (OVT) is a rare condition most frequently associated with pelvic inflammatory disease (PID), malignancy or the immediate postpartum period. This case study reports on a 56-year-old woman who developed OVT 11 days after a positive COVID-19 diagnosis. Imaging including abdominal/pelvic computed tomography, transvaginal Doppler ultrasound and transabdominal pelvic ultrasound failed to definitively diagnose the thrombotic etiology of the patient's presentation. Ultimately, laparoscopic visualization and subsequent oophorectomy were necessary for diagnostic and therapeutic purposes. The patient did not have underlying malignancy, recent surgical history, history of PID or any history of previous thromboembolic events. Therefore, this report contributes further evidence to the growing knowledge of systemic manifestations associated with COVID-19 that may require surgical intervention.

Testicular vein thrombosis mimicking epididymo-orchitis after suspected Covid-19 infection

A 70-year-old man presented to our vein clinic with intermittent and recurrent left testicular and groin pain, clinically resembling epididymo-orchitis. He had never had any genitourinary problems until contracting a severe flu-like illness in January 2020, strongly suspected to have been Covid-19. He had failed to respond on four separate occasions to antibiotics prescribed by his GP and had only responded on these occasions to aspirin. Duplex ultrasonography at our clinic showed thrombosis of the left testicular vein with venous collateral formation. The testicle itself showed mild oedema, but a reduced arterial flow supporting the pain to be secondary to thrombosis. Covid-19 is known to be associated with venous thromboembolic disease, but usually in patients sick enough to be hospitalised and particularly in those requiring intensive care. This man appears to have had a left testicular vein thrombosis secondary to relatively mild Covid-19 infection, as he did not require hospitalisation.
