AbstractAbstract PDF
Combined intrauterine and ectopic (heterotopic) pregnancy occurs in approximately 1 in 30,000 spontaneous gestations. Heterotopic gestations are increased in women who have had reconstructive pelvic surgery, Pelvic inflammatory disease and artificial ovarian hyperstimulation. Patients who require assisted reproductive technologies, such as in vitro fertilization / embryo transfer and gamete intrafallopian transfer, also have an increased risk of a heterotopic pregnancy. We experienced two cases of combined pregnancy following IVF-ET. Following is a report of these cases with a brief review of references.

AbstractAbstract PDF
Alphafetoprotein(AFP) is a glycoprotein synthesized by the fetus early in gestation by the yolk sac and later by the gastrointestinal tract and liver. The concentration of AFP is highest in fetal serum and amniotic fluid around 13th week, and 32nd week in maternal serum. Some conditions are associated with abnormal maternal serum AFP concentration. For examples, neural tube defects, omphalocele, renal anomalies are associated with elevated maternal serum AFP and fetal death, chromosomal trisomies are associated with low level of maternal serum AFP. So maternal serum AFP screening plays a significant role in assessing candidates for prenatal diagnosis and prenatal counselling in pregnant women. This study evaluates the normal ranges of AFP using enzyme immunoassay in normal pregnant women. We studied 500 normal pregnant women who visited the Department of Obstetrics & Gynecology, Yeungnam Medical Center, Yeungnam University during the period through January, 1993 to September, 1996. The group of the study were selected randomly at various gestational ages from 8 to 41 weeks. The results were summarized as follows: 1. The lowest level of AFP in our study group was 2.1ng/ml at 8 weeks of gestation. Thereafter serum alpha-fetoprotein concentrations rose rapidly to reach a peak value at 32nd week. 2. The mean levels of AFP in the primipara and multipara were 166.37+/-12.06ng/ml, and 223.78+/-14.00ng/ml, respectively, showing stastiscally significant difference between these two groups(p<0.01). 3. The mean levels of AFP between mothers who delivered male and female babies were 192.96+/-13.00ng/ml, and 194.29+/-13.84ng/ml, respectively, without statistically significant difference(p>0.05). 4. The normal ranges of maternal serum AFP according to each gestational week were evaulated.
