[Transvaginal ultrasonography in 27 confirmed cases of ectopic pregnancy].

Twenty seven patients having Ectopic Pregnancies were studied prospectively with transvaginal sonography. Ten of them were treated surgically, thirteen with injection of methotrexate and four with expectant management. Ultrasound images were well correlated with clinics, surgical findings and pathology. We believe that the ultrasound image known as "tubal ring" is highly suggesting of early ectopic pregnancy. Since early detection is associated with conservative surgery, expectant management or treatment with methotrexate, and consequently to a better reproductive future, we consider that transvaginal sonography is a reliable method that must be added to traditional ones, in the ectopic pregnancy management.
