Spontaneous uterine venous plexus complicated with ovarian rupture in the third trimester of pregnancy: a case report

It often has an insidious onset and atypical symptoms, develops rapidly, and is easily misdiagnosed. Wewould like to discuss and share this case of spontaneous uterine venous plexus combined with ovarian rupture in the third trimester of pregnancy with colleagues. Case presentation: A pregnant woman, G1P0 at 33+4 weeks of gestation,was admitted to the hospital due to threatened preterm labour on March 3, 2022. After admission, she was treated with tocolytic inhibitors and foetal lung maturation agents. The patient's symptoms did not improve during the treatment. After many examinations, tests, discussions, a diagnosis, and a caesarean section, the patient was finally diagnosed with atypical pregnancy complicated by spontaneous uterine venous plexus and ovarian rupture. Conclusions: Spontaneous rupture of the uterine venous plexus combined with ovarian rupture in late pregnancy is an occult and easily misdiagnosed condition, and the consequences are serious. Clinical attention should be given to the disease and prevention attempted to avoid adverse pregnancy outcomes.
