Implantation of a pregnancy within a Caesarean fibrous tissue scar is considered to be the rarest form of ectopic pregnancy and a life-threatening condition. We conducted a computer search of the English literature of all studies since 2002 to gather updated data on the outcome of such pregnancies. Sixty-six new cases were reported since 2002, possibly reflecting the increasing number of Caesareans currently being performed as well as the more widespread use of the transvaginal scan allowing their earlier detection. Analysis of these women's obstetric history revealed that those at risk for pregnancy in a Caesarean scar appear to have a history of dilatation and curettage, placental pathology, ectopic pregnancy, and IVF. Twenty-one out of 39 for which this information was available (54%) had undergone multiple (> or =2) Caesareans and 13 had previous dilatation and curettage, which might also be an associated factor. We review and discuss the features of contemporary work-ups, including a high index of awareness, a detailed history and a skillful ultrasound examination for an early and accurate diagnosis. Healthcare professionals should be familiar with the possibility of untoward sequelae and how a modern work-up can help in guiding conservative options, thus reducing morbidity and preserving fertility.
OBJECTIVES: To determine the net health consequences, costs, and cost-effectiveness of elective Cesarean delivery (C-section) to prevent perinatal transmission of hepatitis C virus (HCV) in HIV/HCV-coinfected women with suppressed HIV RNA but detectable HCV RNA. DESIGN: Cost-effectiveness analysis using a probabilistic decision model. METHODS: The model compared two strategies: (i) C-section for all coinfected women with suppressed HIV RNA but detectable HCV RNA; (ii) C-section only when indicated based on fetal status. Outcomes included vertical transmission of HCV, maternal mortality, quality-adjusted life expectancy, delivery and HCV treatment costs, and incremental cost-effectiveness ratios. Data were obtained from the literature and national databases. Delivery cost data were from a hospital consortium database. Probability distributions were derived from published confidence intervals or estimated ranges, or calculated using reported sample sizes. RESULTS: Elective C-section in coinfected women with suppressed HIV RNA but detectable HCV RNA would avoid 45 vertical HCV transmissions per 1000 deliveries and increase maternal mortality by one death per 100 000 deliveries. The incremental cost-effectiveness ratio of a recommendation for C-section versus current practice was 3900-6100 dollars per quality-adjusted life year for the mother-child pair. Results are sensitive to the efficacy of C-section in preventing transmission, the probability of vaginal delivery without a recommendation, and rates of maternal acceptance of the recommendation. CONCLUSIONS: Assuming 2000 births/year among HIV/HCV-coinfected women in the United States, a recommendation for elective C-section in these women could avoid an additional 90 perinatal HCV transmissions per year with a risk of one maternal death in 50 years.
