Early diagnosis and precision treatment of right ovarian vein and inferior vena cava thrombosis following caesarean section: A case report

Ovarian vein thrombosis (OVT) is a rare medical complication that is most often diagnosed in the post-partum period. OVT can lead to conditions, including sepsis, inferior vena cava (IVC), pulmonary emboli and mortality. The current study outlines a case of a patient who experienced pain in the lower abdomen and waist without fever postpartum following caesarean section (CS). Plasma FDP, D-Dimer and fibrinogen levels were markedly increased following CS and this was an indicator of the rapid progression of blood coagulation and fibrinolysis. Increased maternal lipid may be one of the risk factors for thrombosis. Based on the clinical presentation, a CT scan demonstrated thrombosis of the right ovarian vein and inferior vena cava, and a diagnosis of OVT and IVC thrombosis was subsequently made. In the current case, an anticoagulant therapy was started with a subcutaneous injection low molecular weight heparin calcium, an intravenous urokinase drip as a thrombolytic agent and implantation of inferior vena cava filters as a novel method of treatment for thrombosis. The patient was discharged from hospital 20 days following treatment in a good condition. The current study reports a case of OVT associated with IVC that was successfully managed without complication.
