Cervico-isthmic pregnancy successfully treated with bipolar resection following methotrexate administration: case report and literature review

Abstract

Cervico-isthmic pregnancy is a rare form of ectopic pregnancy associated with a high morbidity and mortality rate. Recent advances in high-resolution ultrasound have made the diagnosis of early cervico-isthmic pregnancies easier. Early diagnosis allows a more conservative therapeutic approach that avoids hysterectomy and preserves fertility. Here is reported a case of viable cervico-isthmic pregnancy successfully treated with resectoscopy after failed systemic and local (hysteroscopic) methotrexate administration. The resectoscopic excision of the cervico-isthmic pregnancy was carried out with the technique of slicing, using a 27 bipolar resectoscope with a 4-mm loop. The procedure was successful with the complete removal of the ectopic pregnancy, while maintaining satisfactory haemostasis. A literature review shows that no consensus exists for the treatment of cervico-isthmic pregnancies. We report a case of viable cervico-isthmic pregnancy successfully treated with resectoscopy after failed systemic and local (hysteroscopical) methotrexate administration. The resectoscopic excision of cervico-isthmic pregnancy was carried out with the technique of slicing, using a 27 bipolar resectoscope with a 4-mm loop. The procedure was successful with the complete removal of the ectopic pregnancy, while maintaining satisfactory haemostasis.
