Puerperal ovarian vein thrombophlebitis is an uncommon condition that usually develops in the immediate postpartum period. Computed tomography, magnetic resonance imaging, Doppler ultrasound and exploratory laparotomy may be performed to diagnose it. A woman developed worsening abdominal pain 6 weeks postpartum. Laparoscopic intervention allowed treatment of late-onset, left-sided puerperal ovarian vein thrombophlebitis. The disorder may develop much later after delivery than expected and can be successfully treated laparoscopically.
