[Ultrasound diagnosis of ectopic pregnancy : prospective study of 200 cases].

BACKGROUND: the ectopic pregnancy is responsible for 10% of maternal mortality in the first quarter. Progress in transvaginal ultrasound; have revolutionized the diagnosis of ectopic pregnancy, allowing her diagnosis earlier.

AIM: To evaluate the contribution of ultrasonography in the diagnosis of ectopic pregnancy.

METHODS: A prospective study about 200 patients hospitalized for ectopic pregnancy between July 2009 and July 2011. All patients underwent a transvaginal ultrasound.

RESULTS: The average age was 25.4 years. The study of the endometrium showed an endometrial thickness of 10.1mm in 152 cases. An haematosalpinx was observed in 71% of cases. The average size was 30.5mm. Hemoperitoneum was observed in 64.5% of cases. An ectopic gestational sac with embryo was found in 9 cases (4.5%). In 51 cases no pathological sonographic signs were noted.

CONCLUSION: The transvaginal ultrasound is the method of choice in the diagnosis of ectopic pregnancy. However the use of BHCG is still necessary.
