Knowledge about contraception in women undergoing repeat voluntary abortions, and means of prevention.

AIMS: Despite reliable and effective means of contraception, cases of repeat abortion are on the increase in all developed countries. The aim of this work was to determine whether women undergoing repeat abortions are exposed to risk factors which might be amenable to preventative measures, and the methods employed by carers in these cases. METHODS: We set out to evaluate practices in the Family Planning Centre of l'Hôpital Jean Verdier (Bondy, France) by sending a questionnaire to 147 women who had undergone two abortions up to 1997, and by conducting interviews with the care team. Thirty patients responded to the questionnaire. RESULTS: Twenty-two women (73%) underwent one or more further abortions between 1999 and 2000. Twenty-seven out of 30 women were unaware of the existence of emergency contraception. The 'morning after' pill, indicated for cases of unprotected sex, was unknown to one woman in two (15), nine out of 30 did not know what 'back-up' measures they should take after missing a dose of the contraceptive pill. Psychological problems were found in nine cases. These were followed up with a psychological consultation in three cases. The information given to the patients by the carers was the same irrespective of the number of abortions. Poverty and psychological problems were noted by the carers. CONCLUSION: Patients who have undergone two abortions might benefit, in addition to their routine visits, from a consultation with a psychologist and a consultation providing information about contraception. Providing the contraceptive pill free of charge to low-income patients is essential.

[Evaluation of the risk of abortion abuse resulting from the two-week legal delay in France].

OBJECTIVE: The legal delay for abortion in France has recently been prolonged from 10 (12 weeks of amenorrhea) to 12 weeks (14 weeks of amenorrhea). With the progress in sonography, certain foetuses may exhibit malformations during the first trimester. Diagnosis of foetal gender at 12 weeks of amenorrhea is sometimes possible. We studied the possibility that the prolonged legal delay before abortion might incite women to abort, simply on sonographic criteria. METHODS: Our enquiry was conducted in March 2001 in the department of Obstetrics and Gynaecology of the Jean Verdier hospital in Bondy. Two questionnaires were drawn-up by the Medical Ethics Laboratory of the Necker Hospital in Paris and were distributed to 128 women and 24 nurses. RESULTS: Recourse to abortion was high if laparoschisis or the absence of a hand was revealed, low in the case of opacity of the neck, and almost inexistent in the case of unwanted gender, in a female population with less than one child. CONCLUSION: A national consensus on foetal abnormalities to be searched for, and not to be searched for (Number of fingers? Upper lip?...) and the eventual detection of the gender during sonography of the 1st trimester is urgent in view of the technological progress made. Clear and reassuring information is essential when confronted with foetal abnormalities and must lead to complete and precise antenatal diagnosis (caryotyping, sonographic control 2 or 3 weeks later).

Uteroplacental circulation development: Doppler assessment and clinical importance.

In the first weeks of pregnancy, columns of endovascular cytotrophoblastic plugs develop in the lumen of spiral arteries. Morphologic data show that these plugs become loosened as soon as the end of the second month and the intervillous circulation of maternal blood is likely to be established progressively between the 8th and 12th weeks. The disorganization of the musculo-elastic layers of these vessels provokes a dramatic decrease in vascular tone in the uteroplacental circulation. These modifications appear to govern the establishment of a low-pressure blood flow in the placenta, and hence determine the quality of uteroplacental circulation and normal fetal growth. Placental bed biopsies in women with pre-eclampsia and in a proportion of pregnancies with intrauterine growth retardation have shown that these physiologic changes were absent in the myometrial segments of spiral arteries. Recently, colour Doppler was used to assess intervillous and spiral artery flow in early pregnancy, confirming in vivo free intervillous flow at 12 weeks and a progressive significant decrease in spiral artery resistance with advancing gestation during the first trimester. However, certain data at an earlier gestational age are still contradictory. Particularly, the exact nature of the contents of the intervillous space before 8 weeks, and whether or not this fluid can be considered maternal blood, remains controversial.

Intervillous and spiral artery flows in normal pregnancies between 5 and 10 weeks of amenorrhea using color Doppler ultrasonography.

OBJECTIVE: The aim of our study was to investigate early placental circulation development and spiral and uterine artery flows in normal 1st-trimester pregnancies. METHODS: A prospective study of intervillous and spiral artery flows in 49 normal pregnancies (5-10 weeks of amenorrhea) was performed. Transvaginal color and pulsed-wave Doppler techniques (6-MHz probe) were used as routine ultrasound scanning modalities before pregnancy termination for psychosocial reasons. RESULTS: In all pregnancies, between 5 and 10 weeks, continuous nonpulsatile intervillous flow (mean V(max) 3.55 cm/s) and spiral artery flow (mean peak systolic velocity 16.2 cm/s, mean diastolic index D/S 0.49 +/- 0.089) were detected. In the 47 women in whom the uterine artery flow was measured, the mean peak systolic velocity was 67.5 cm/s, the mean diastolic index was 0.12, and bilateral notching was observed. CONCLUSIONS: In all cases, between 5 and 10 weeks, slow and continuous nonpulsatile intrachorionic flow could be detected, whereas pulsatile flow was detected in spiral arteries. The true nature of this early intervillous circulation remains to be determined.
