BACKGROUND: Septic puerperal ovarian vein thrombosis (SPOVT) is one of the underlying etiologies of puerperal fever. A correct diagnosis of this condition is important because adequate treatment requires additional administration of anticoagulants. The purpose of this study was to evaluate the role of duplex color Doppler ultrasound (CDUS), computed tomography (CT), and magnetic resonance angiography (MRA) in the detection of SPOVT. METHODS: Twenty-six patients with puerperal fever suspected to be due to SPOVT and unresponsive to broad antibiotic treatment for at least 48 h were included in a prospective study using CDUS, CT, and MR imaging including MRA. Examinations were analyzed and then correlated to a standard of reference gathered from surgical and clinical follow-up data and from results of imaging. RESULTS: SPOVT was present in nine patients (right side n = 8, bilateral n = 1). CDUS was inconclusive due to gaseous distention of the bowel or obesity in 13 of 26 cases. After counting inconclusive findings as wrong results for statistical purposes, sensitivity, specificity, and accuracy for CDUS were 55.6%, 41.2%, and 46.2%, respectively. CT had a sensitivity of 77.8% with a specificity of 62.5%; accuracy was 68.0%. MRA rendered conclusive results in all evaluated patients, resulting in a sensitivity and specificity of 100%. CONCLUSION: MRA is recommended in all patients with inconclusive CDUS findings and persistent suspicion for SPOVT. CT has the advantage of more rapid access and lower cost and thus will probably remain a sufficiently accurate alternative.
