Analysis of clinical diagnosis and treatment of caesarean scar pregnancy

Objective: To describe the clinical characteristics,diagnosis and symptoms of cesarean scar pregnancy（CSP） and evaluate the effects of different treatments. Methods: 7 cases of CSP were retrospectively analyzed.The clinical symptoms,ultrasound image and different treatments were then evaluated. Results: All the 7 cases were diagnosed by transvaginal ultrasound.3 of them were found before any treatment.The 3 early-diagnosed cases were associated with less haemorrhage（＜200mL）,while the other 4 suffered severe vaginal bleeding（＞1 000mL）.All the cases were initially managed with conservative treatments including systemically methotrexate（MTX） injection or uterine artery embolization（UAE） with or without intra-arterial injection of MTX.6 of them were successful,and hysterectomy was performed in 1 case at the patient’s insistence. Conclusion: Caesarean scar pregnancy often results in life-threatening vaginal bleeding.Early diagnosis and management could minimize such complications.Conservative treatment may be successful in most cases,and UAE could be the first choice.
