Cervical Ectopic Pregnancy: Role of Imaging in Diagnosis and Management

Cervical pregnancy is rare form of ectopic pregnancy with implantation in the endocervical canal and accounts for less than 1% of all ectopic gestation. Ultrasonography has important role both in diagnosis and treatment. Early diagnosis in asymptomatic phase is possible especially in IVF pregnancies as these women are in constant clinical supervision. The transvaginal ultrasonography is safe and helpful in clinching diagnosis. Methotrexate (MTX) is the first line management in hemodynamically stable patient. In cases with presence of cardiac activity, MTX can be combined with ultrasound guided local injection of potassium chloride. Measures like intracervical vasopressin injection, ligation of cervico-vaginal division of uterine artery or use of inflated foley’s bulb can be used prior to conservative surgery like endocervical curettage to reduce chances of bleeding. Interventional radiological procedure like uterine artery embolization (UAE) is another option if available, before curettage to minimise bleeding
