Diagnosis of ectopic pregnancy by vaginal ultrasonography in combination with a discriminatory serum hCG level of 1000 IU/1 (IRP)

Abstract: should not be regarded as incorrect solely on the basis of negative punch biopsy histology. IU/l (IRP). 41 had intrauterine pregnancies (38%) and three had heterotopic pregnancies (3%). Sixty five patients had ectopic pregnancy, 63 of which were scanned, 55 (87%) by vaginal ultrasound. Two patients, one with a cornual and one with a heterotopic pregnancy were not diagnosed correctly on vaginal scanning. The remaining two heterotopic pregnancies were correctly diagnosed. The sensitivity of diagnosing ectopic pr… Show more

“…In recent years, the incidence of ectopic pregnancy has increased, and although only approximately 1% of gestations are extrauterine, these account for 4% of direct maternal deaths [ 24 ]. In the presence of established risk factors or clinical suspicion for ectopic pregnancy, early ultrasonography is recommended [ 25 , 26 ]. In our study, the incidence of ectopic pregnancy was 0.6%.…”

“…In addition, ultrasound may show the presence or absence of an adnexal mass or free fluid in the pouch of Douglas. If the ultrasound scan identities an intrauterine gestation, this virtually excludes ectopic pregnancy, as intrauterine and tubal pregnancy co‐exist infrequently — approximately 1:2600 62 to 1:6770 67 spontaneous pregnancies. A vaginal ultrasound scan provides a significant advance in pelvic imaging with the proximity of its high frequency transducer to the pelvic organs 64 .…”

“…A vaginal ultrasound scan provides a significant advance in pelvic imaging with the proximity of its high frequency transducer to the pelvic organs 64 . When hCG levels are greater than 1000 IU/l, an intrauterine gestational sac should be detected by vaginal ultrasonography, which is about one week earlier than with an abdominal ultrasound scan 65–67 . Failure to visualise an intrauterine gestational sac with an hCG level of more than 1000 IU/l, or the direct visualisation of an ectopically placed gestational sac by vaginal ultrasound, allows the earlier diagnosis of ectopic pregnancy 68 .…”
