Postpartum septic pelvic thrombophlebitis and ovarian vein thrombosis after caesarean section: a rare case report.

BACKGROUND Septic pelvic thrombophlebitis (SPT) is a well-recognized but rare puerperal complication that has two types: ovarian vein thrombophlebitis (OVT) and deep septic pelvic thrombophlebitis (DSPT). The present case report describes the clinical and imaging findings of a female patient diagnosed with right ovarian vein infectious thrombophlebitis after caesarean section (C-section). CASE PRESENTATION A 35-year-old G3P2 female who presented with a foetal vein Galen malformation at 41 weeks of gestation underwent C-section. The patient had high fever after C-section, and anti-inflammatory treatment was not effective within 1 week. An abdominal wall incision haematoma was found, and a second surgery for the removal of the abdominal wall haematoma was performed. The patient was ultimately diagnosed with abdominal incision haematoma and right ovarian vein infectious thrombophlebitis after C-section. We used imipenem and tigecycline to strengthen the anti-inflammatory effects, simultaneously administrating low-molecular-weight heparin and warfarin as anticoagulant therapy. On the 30th day after C-section, the right ovarian vein thrombus disappeared. CONCLUSION This case illustrates the need to consider the potential relationship between abdominal incision haematoma and ovarian vein thrombophlebitis. Despite advances in the management of venous thromboembolism globally, more data on epidemiology in terms of first incidence, prevalence, recurrence and risk factors, management of bleeding complications, and increased awareness in Asian populations are necessary.
