Bilateral ectopic gestation
, although rare, should be regarded as the differential diagnosis for ectopic pregnancy, especially in assisted reproductive technology cases and high titers of [beta]-HCG (more than 100000).
The detection rates of different types of ectopic gestation
and different sizes of mass using transabdominal sonography in combination of transvaginal sonography were higher than that of transabdominal sonography and transvaginal sonography (P<0.
Monitoring [beta]-hCG titers following conservative management of suspected ectopic pregnancies is important, not only to diagnose persistent ectopic gestation
, but also to rule out the presence of malignant trophoblastic diseases (11).
Resolution of hormonal markers of ectopic gestation
: a randomized trial comparing single-dose intramuscular methctrexate with salpingostomy Obstet Gynecol 1998; 92:989-994.
In a followup study by Tuomivaara  on 929 infertile couple showed an ectopic rate of 9% indicating very strong association between infertility and ectopic gestation
. The two principal risk factors among infertile subjects could be genital tract infection and tubal surgery.
(4,5) Similarly, a history of delayed menstruation or prior ectopic gestation
suggests the possibility of an ectopic pregnancy.
Repeat ipsilateral ectopic gestation
: a series of 3 cases.
Suspected ectopic pregnancy or pregnancy occurring after tuboplasty or phor ectopic gestation
(1) Ectopic pregnancy causes foetal wastage, maternal morbidity and mortality and impairment of subsequent fertility due to repeat ectopic gestation
which occurs in 10-15% of cases.
Heterotopic pregnancies can pose a diagnostic dilemma because an early transvaginal ultrasound may not diagnose an ectopic gestation
in all cases.
24 (70.58%) cases had ampullary region tubal ectopic gestation
, 7(20.58%) isthmic, 1(2.94%) infundibular, 1 (2.94%) fimbrial, this shows that ampullary region tubal ectopic is the most common site for tubal ectopic gestation
was located at the site of interruption in 71% of cases.
