Left ovarian vein thrombosis suspected during cesarean section and confirmed postoperatively: a case report and review of the literature

This case illustrates that when unexpected adnexal venous abnormalities are encountered prior to abdominal closure during cesarean delivery, OVT should be considered. In such situations, a structured differential diagnosis and multidisciplinary input are essential, and timely postoperative imaging should be obtained. In carefully selected scenarios under diagnostic uncertainty, selective ligation of a suspicious venous branch may be considered as an intraoperative risk-mitigation step, followed by standard therapeutic anticoagulation, with antibiotics administered when indicated. At 42-day follow-up, ultrasound showed no sonographic evidence of residual thrombus on the ligated side, with improved left-sided parauterine venous dilatation compared with the contralateral side.
