Reliability of transvaginal ultrasound in the diagnosis of ectopic pregnancy

Transvaginal ultrasound [TVS] was used in the assessment of 101 patients clinically suspected of having an ectopic pregnancy [EP]. Transvaginal ultrasound allowed earlier demonstration of an interauterine pregnancy in 9 [8.8%] patients without confusion with a pseudosac. Of the 76 patients with an ectopic pregnancy, this was positively identified in 28 [36.8%] patients. A live extrauterine fetus was seen in 3 [3.9%] patients, 48 [63.1%] patients had scan findings suggestive of ectopic. Transvaginal sonography is advocated as the technique of choice in patients suspected of having an ectopic pregnancy
