Emergency internal iliac artery temporary occlusion after massive hemorrhage during surgery of cesarean scar pregnancy: A case report.

BACKGROUND: Cesarean scar pregnancy (CSP) is rare but may result in uterine rupture during pregnancy or massive hemorrhage during abortion procedures. Awareness of this condition is increasing, and most patients with CSP are now diagnosed early and can be managed safely. However, some atypical patients are misdiagnosed, and their surgical risks are underestimated, increasing the risk of fatal hemorrhage. CASE SUMMARY: A 27-year-old Asian woman visited our institution because of abnormal pregnancy, and she was diagnosed with a hydatidiform mole through trans-vaginal ultrasound (TVS). Under hysteroscopy, a large amount of placental tissue was found in the scar of the lower uterine segment, and a sudden massive hemorrhage occurred during the removal process. The bilateral internal iliac arteries were temporarily blocked under laparoscopy, and scar resection and repair were rapidly performed. She was discharged in good condition 5 d after the operation. CONCLUSION: Although TVS is widely used in the diagnosis of CSP, delays in the diagnosis of atypical CSP remain. Surgical treatment following internal iliac artery temporary occlusion may be an appropriate management method for unanticipated massive hemorrhage during CSP surgery.
