Abstract: | The role of expectant management was evaluated in 80 women inwhom clinical examination, including vaginal ultrasound, hadfailed to identify the location of an early pregnancy. In 45cases, spontaneous resolution of the pregnancy products occurred.A normal intra-uterine pregnancy was diagnosed in 12 patients.A total of 23 patients underwent active therapeutic measuresdue to an ectopic pregnancy (n = 16) or a spontaneous abortion(n = 7). The effectiveness of different diagnostic measuresto identify patients suitable for expectant management was analysed.In 33/34 patients (97%) with a relative daily human chorionicgonadotrophin (HCG) change of <5%, and a serum progesteroneconcentration of <20 nmol/l, spontaneous resolution of thepregnancy products occurred. Among 46 cases, with a relativedaily HCG change of >5% and/or serum progesterone>20 nmol/l, active therapeutic measures were carried outin 22 cases (48%), a normal intra-uterine pregnancy was diagnosedin 12 cases (26%) and spontaneous resolution of the pregnancyproducts occurred in 12 cases (26%). In conclusion, the combinationof a single progesterone assay and serial HCG determinationsretrospectively identified early pregnancies of uncertain locationin whom expectant management was a safe management option. |
