ABSTRACT
Early diagnosis of rptured and unruptured tubal pregnancy became more accurate with the introduction oftransvaginal sonographic equipment. The manangement principle of tubal pregnancy might be changed according to thesonographic findings. The purposes of this study were to define the sonographic findings of tubal pregnancy and todetermine whether it is possible to differentiate the unruptured tubal pregnancies from the ruptured onesdepending on the sonographic findings. The authors investigated the sonographic findings of the surgicallyconfirmed 25 tubal pregnancy patients. There were 22(88%) unruptured and 3(12%) ruptured tubal pregnancies.Unruptured pregnancies showed tubal ring in 8, well defined hematosalpinx in 11, and poorly defined hematosalpinxin 2 patients. Ruptured pregnancies showed tubal sac with irregular margin in 2, and ill-defined hematosalpinx inone patient. In summary, well marginated tubal ring and hematosalpinx suggested unruptured tubal pregnancy, whiletubal sac with irregular margin suggested ruptured pregnancy. However, it was difficult to differentiate theunruptured tubal pregnancy from the ruptured one when hematosalpinx was ill-defined.
