Postpartum ovarian vein thrombosis manifesting as acute appendicitis: a case report

Postpartum ovarian thrombosis is an uncommon condition. It appears with the nonspecific, predominantly right-sided abdominal symptoms and must be differentiated from other acute visceral conditions. If left untreated, postpartum ovarian thrombosis can have severe consequences, including sepsis, pulmonary embolism, and even death. Momentarily, there are no specific guidelines for postpartum ovarian thrombosis management. We present a case of postpartum ovarian thrombosis admitted to our hospital with symptoms of acute appendicitis. CASE PRESENTATION : A 39-year-old Omani obese multiparous woman of Afro-Arab origin was admitted with acute symptoms, mainly abdominal pain, fever, and vomiting 1 week postpartum. Clinical picture and biochemical profile did not exhibit a recognizable pattern. Ultrasonography excluded retained products of conception. Computerized scan for abdomen and pelvis with oral and intravenous contrast reported a dilated tubular structure in the right adnexa extending up to the right renal hilum level with surrounding inflammation. Those findings were consistent with the thrombophlebitis of the right ovarian vein. Blood cultures and sensitivity showed group A β-hemolytic streptococci sensitive to penicillin G and clindamycin. The patient was treated successfully with antibiotics and therapeutic anticoagulants and discharged home 3 days later; follow-up was arranged.

This pathology is an exceptional entity in Oman. Therefore, awareness of this unique condition is required so that clinicians will be vigilant, exploring similar cases with imaging and avoiding unnecessary surgical interventions.
