[Acute per-partum feto-fetal transfusion. A case study on two sets of twins]. / La transfusion foeto-foetale per-partum: à propos de deux observations.

Description of acute per-partum feto-fetal transfusion. The risk of twin-twin transfusion syndrome in monochorionic twin pregnancies is well known. This pathology starts in the second trimester and has a chronic course. Acute per-partum feto-fetal transfusion seems to be less frequent and has not been studied. In the study, we described two cases of acute per-partum feto-fetal transfusion. The outcomes of the pregnancies were as follows: following a successful delivery, the first set of twins presented hypovolemic shock at birth due to an acute anemia. The second set of twins was polyglobulic, but otherwise healthy at birth. The risk of hypovolemic shock seems to be unpredictable, even if the pregnancy is monitored. Obstetricians and pediatricians must keep this pathology in mind when dealing with this kind of pregnancy. Moreover, it would be interesting to obtain systematically a full blood count of each set of twins of monochorionic pregnancies, in order to detect every case of feto-oetal transfusion.

[What public health measures could reduce antenatal exposure to tobacco and improve the quality of perinatal care: the gynecologist-obstetrician's point of view]. / Quelles sont les mesures de santé publique susceptibles de réduire l'exposition anténatale au tabac et d'améliorer les indicateurs de qualité des soins périnatals? Le point de vue du gynécologue-obstétricien.

The progression of addiction to smoking among young women is particularly alarming. The fatal effects of the nicotine-poisoning on the pregnancy and on the child constitute a serious public health issue. For young women, the period of maternity plays an essential educational role. Contact with medical care during pregnancy offers a special opportunity to establish a sound basis for health. Clinicians must strive to help women become fully aware of the fatal effects of smoking, providing methods and support for abstinence through a global, structured strategy of health care. The "Maternity without tobacco" network was developed to achieve these objectives. Expired CO analysis can be an interesting tool to search for active or passive addiction to smoking, and more generally carbon monoxide poisoning.

Pregnancy after myocardial infarction.

UNLABELLED: The occurrence of pregnancy in a patient after myocardial infarction remains a dilemma for both the cardiologist and the obstetrician. The majority of obstetricians and cardiologists are very reticent about pregnancy in a woman suffering from coronary disease. AIMS: The aims of this study are to evaluate the risks, the prognosis of pregnancy for women who had suffered from myocardial infarction and to propose guidelines for pre-pregnancy counselling and medical supervision of the pregnancy and delivery. METHODS: A review of literature has revealed 30 cases, 14 of which are sufficiently documented. Only one of these patients requested pre-pregnancy counselling. We add to this experience the case of a patient who, having had an infarction, was authorized to begin pregnancy. RESULTS: Most of the pregnancies in these patients evolve satisfactorily if the more frequent cardiovascular complications are diagnosed and treated rapidly. During the pregnancy, rest is the rule and any situation which risks to increase the myocardial work-load should be avoided. Normal vaginal delivery with epidural anesthesia is the preferred method. CONCLUSION: The maternal and fetal prognosis is good on condition of performing a pre-pregnancy examination and of setting up a multi-discipline surveillance of the pregnancy. The review of the literature does not confirm the surrounding pessimism concerning the patients becoming pregnant after myocardial infarction.

Hip-flexed postures do not affect local anaesthetic spread following induction of epidural analgesia for labour.

Hip-flexed postures enlarging the pelvic diameter are used to improve the obstetric course of labour. Although most investigations show that lateral and sitting positions do not affect the spread of epidural analgesia, the effect of recently introduced hip-flexed postures has yet to be confirmed. This prospective randomised study included 93 parturients. Ropivacaine 0.1% 12 mL plus sufentanil 0.5 micrograms/mL was administered epidurally over a period of 6 min in one of four postures: sitting, right hip-flexed left lateral position, left hip-flexed right lateral position and supine 30 degrees lateral tilt as a control group. Left and right cephalad and sacral epidural spread were measured every 2 min over a period of 30 min. Pain relief, motor blockade and maternal and fetal side effects were noted. The total epidural spread was 15+/-0.3 dermatomes and the upper level of thermo-algesic blockade T7-T8 (range T3 to T10) in all groups. There were no differences between groups in left or right total spread or upper level of epidural blockade, time to maximal block or pain relief. There was no motor block nor any maternal or fetal side effects. The power of the study (1 - beta) was 93%. We conclude that, for the three hip-flexed postures tested, position does not influence local anaesthetic spread or symmetry of thermo-algesic blockade after induction of obstetric epidural analgesia.

[Marfan syndrome and pregnancy. Apropos of 4 cases]. / Syndrome de Marfan et grossesse. A propos de quatre cas.

OBJECTIVES: To create a follow-up protocol for pregnant patients with Marfan syndrome. PATIENTS AND METHODS: We retrospectively reviewed the charts of patients who delivered in the Jeanne de Flandre University Hospital between June 1996 and June 1999. Four pregnant patients with Marfan syndrome were identified. RESULTS: Three of these patients had Bentall procedure. One of them had vaginal delivery and the two others underwent cesarean section. One of these two patients developed aortic valve thrombus at 14 weeks of amenorrhea. The fourth patient did not have surgery and had two vaginal deliveries. DISCUSSION: According to our results and after reviewing literature pregnant patients with Marfan syndrome were divided into two groups. The 1st group was comprised of patients who underwent Bentall procedure. The 2nd one was comprised of patients who did not undergo any surgical procedure. The possibility of vaginal delivery for patients who underwent Bentall procedure (one case) and the interest of Propanolol and anticoagulant treatment are emphasized. CONCLUSION: The multivariant approach of pregnant patients with Marfan syndrome is stressed out with special reference to the potential complications of this syndrome such as aortic dissection and to the problems related to the anticoagulant treatment.

[Postpartum hemorrhage: frequency, consequences in terms of health status, and risk factors before delivery]. / Hémorragies du post-partum: fréquence, conséquences en termes de santé et facteurs de risque avant l'accouchement.

In the developing countries, postpartum hemorrhage is the leading cause of maternal death and affects approximately 1% of pregnant women. In developed countries like ours, maternal mortality is one hundred fold lower but remains the cause of maternal death for about 10 women per 100,000 births. In the last decade, French confidential inquiries show that the number of maternal deaths by postpartum hemorrhage are probably the double of the number in nearby countries, whereas hemorrhage should no longer be the leading cause of maternal death in our countries. Postpartum hemorrhage is defined as the loss of 500 ml or more blood in the 24 hours following delivery (5% of deliveries), but maternal tolerance is really threatened starting from 1,000 ml (1% of the women approximately). "Life-threatening" situations concern approximately one patient in one thousand so that obstetricians are rarely faced with this situation. For maternal morbidity or mortality, the risk factors of postpartum hemorrhage are nearly the same: maternal age, multiple pregnancies, uterine scars, abruptio placentae, cesarean section, poor social condition and absence of prenatal care constitute the main risk factors of postpartum hemorrhage. Maternal age must be kept in mind because it is the most related to mortality by hemorrhage, even if prevention is difficult. However, progress in delivery care which are applied to all the patients could make it possible to limit the harmful effects of this risk factor. A recent study showed that organizational factors also part of the factors of risk of maternal morbidity/mortality and could be studied for intervention.

[Immunologic aspects of endometriosis]. / Aspects immunologiques de l'endométriose.

Endometriosis is thought to result from implantation of endometrial tissue swept back into the pelvic cavity during menstruation, or from coelomic metaplasia of the peritoneum. Yet not all women with menstrual reflux develop endometriosis. The authors present and analyse the arguments in favour of immune system involvement in the physiopathology of this frequent disease. A knowledge of the antigens that have been recognized and of the operative mechanisms will probably make it possible to understand better the repercussions of endometriosis on fertility, to develop diagnostic methods less traumatic than those available at present and to modulate treatments and improve their effectiveness.

[Cerebral aneurysms and pregnancy: 4 cases]. / Anévrysmes cérébraux et grossesse: 4 cas.

Haemorrhagic cerebral accidents are the commonest neurosurgical diagnoses made in pregnancy. The state of pregnancy makes it more likely that an arterial or an arteriovenous aneurysm will rupture and this is the principal cause of most haemorrhages. They occur more often in primiparae in the third trimester of pregnancy. The clinical picture is classical. The conformation of the diagnosis is made by scanning and angiography. The main differential diagnosis is eclampsia. Neurosurgical treatment should be carried out immediately whenever possible in order to avoid the two great risks that follow, namely recurrence of haemorrhage and secondly ischaemia. As far as the obstetric side is concerned, Caesarean section would only be indicated if: the clinical state of the mother is severe with coma and brain stem damage when the child is viable, if there is symptomatic vascular malformation diagnosed at term, if there is haemorrhagic arteriovenous malformation which is highly liable to occur and cannot be operated on without risks for the child if viable, if, finally, the interval between the surgical treatment of the condition and labour is less than 8 days. In all other cases a vaginal delivery is preferable under epidural anaesthetic which should be given if medical induction is carried out, and where instrumental delivery is being carried out systematically, unless radical treatment is being performed. The prognosis which is, in spite of all steps that may be taken, poor, depends on the initial neurosurgical stage and the nature of the causes of lesion and the possibilities of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

[Hydrocephalus with cerebrospinal fluid shunts and pregnancy: 2 cases]. / Hydrocéphalie appareillée et grossesse: 2 cas.

During pregnancy 50% of all cases with a ventriculo-peritoneal shunt malfunction. This is because of anatomo-physiological changes associated with the pregnant state, and shows itself as a rise in intracranial tension. There were no acute neurological complications at term; with the malfunction of the shunt distally, vaginal delivery is preferable. It is not necessary routinely to carry out instrumental delivery.

[Willebrand's disease and pregnancy. Fifteen cases]. / Maladie de Willebrand et grossesse. A propos de 15 cas.

Willebrand's disease, the most frequent inborn coagulopathy, is defined as a deficiency in Willebrand's factor required for normal hemostasis as a mediator in platelet adhesion to the subendothelium and which also contributes to plasma coagulation pathway (by preserving the coagulating activity of factor VIII). Classically, Willebrand's disease improves somewhat during pregnancy. We followed 15 pregnancies in 12 patients with Willebrand's disease in an attempt to determine the best management strategy to reduce the risk of bleeding during delivery. This risk can be assessed on the basis of prior history of bleeding and the laboratory tests and reduced by administration of concentrated Willebrand's factor at 8 months gestation. In patients with type I disease, desmopressin is proposed as curative treatment during the post partum period. Antenatal diagnosis is possible in the most severe forms. Programmed delivery is recommended. Spinal analgesia is contraindicated.

[Intrauterine growth retardation associated with a mosaic trisomy 20 limited to the placenta. A case report]. / Retard de croissance intra-utérin associé à une trisomie 20 en mosaïque limitée au placenta. A propos d'un cas.

When an amniocentesis was performed to determine fetal age, the karyotype was found to be a trisomy-20 mosaic, which could not be confirmed at birth on peripheral blood but which was confirmed at the cytogenetic examination of the placenta. Fetal growth impairment occurred. Mosaic trisomy in the placenta alone is known to affect fetal development. Normally, lethal, mosaic trisomy found during antenatal diagnosis in a viable fetus with no detectable malformation suggests an extra-embryo anomaly. The risk of spontaneous abortion and fetal growth retardation is however increased making strict echographic surveillance essential in these pregnancies.

[Laparoscopic treatment of extra-uterine pregnancy. Results apropos of a series of 109 cases]. / Traitement coelioscopique de la grossesse extra-utérine. Résultats à propos d'une série de 109 cas.

We report our experience concerning the laparoscopic treatment of ectopic pregnancy (EP). One-hundred and nine women with EP were treated in our department over a 4 year period, between February 1988 (date of our first laparoscopic surgery for EP) and December 1991. Twenty-two of these women underwent laparotomy and the remaining 87 laparoscopic surgery alone. Four therapeutic failures were noted in women treated by laparoscopy. Our results are compared with those of other series and the indications, as well as the modalities of laparoscopic treatment are detailed. It is concluded that laparoscopic surgery of EP is a reliable method which must always be considered, except for a few rare indications.

[Cerebral tumors and pregnancy. Apropos of 8 cases]. / Tumeurs cérébrales et grossesse. A propos de huit cas.

Pregnancy is an aggravating factor for brain tumours on which it acts by three mechanism: acceleration of tumour growth, increase of peritumoral oedema and the immunotolerance to foreign tissue antigens that is proper to pregnancy. Histologically, the brain tumour most frequently encountered is glioma, usually revealed during the third trimester. Brain tumours is pregnant women have no special clinical features, and their diagnosis rests on computerized tomography or nuclear magnetic resonance completed, if required, by stereotactic biopsy. Following a review of the literature, the authors present an updated description of the neurological and obstetrical actions to be taken, illustrated by a report of eight personal cases. The indications for surgery depend on the site and histological nature of the tumour. As regards obstetrical measures, induced therapeutic abortion and caesarean section, no longer routinely performed, are now being replaced by vaginal delivery with systematic instrumental extraction. In both mother and foetus the prognosis has improved over the last ten year, but it remains very sombre.

[Anaesthetic management for caesarean delivery and Creutzfeldt-Jakob disease]. / Anesthésie pour césarienne et maladie de Creutzfeldt-Jakob.

Variant Creutzfeldt-Jakob disease (vCJD) is the only form of prion diseases linked to bovine spongiform encephalopathy (BSE). The surgical and anaesthetic management in patients having Creutzfeldt-Jakob disease is rare. Maternofoetal and human transmission of Creutzfeldt-Jakob disease is still unknown. The principles for managing these new risks are not described in obstetric recommendations. We report the case of an 18-year-old woman, who developed the variant Creutzfeldt-Jakob disease during her pregnancy.

[Transfusion and postpartum haemorrhage]. / Transfusion et hémorragie du post-partum.

Postpartum haemorrhage is the leading cause of maternal death in France and worldwide. Guidelines help to conduct a timed management and to reduce maternal morbidity and mortality. Rescue and surgical care, transfusion and monitoring have to be previously organized.

[Pelvic trauma and pregnancy. Literature review and case report]. / Traumatisme du bassin et grossesse. Revue de la littérature à propos d'un cas.

The authors are dealing with a case of a pelvic fracture (right superior pubic ramus) after a road traffic accident to a patient who arise a pregnancy with twins at twenty five weeks pregnant. Seven per cent of a road traffic accident affect pregnancy with a maternal death rate from eight to sixteen per cent and a fetal death rate up to fifty seven per cent. Pelvic trauma are more deleterious during the pregnancy because of the gravide uterus, of the abdominal injuries binding more often, and of pregnancy secondary maternal physiology which lead to delay diagnosis and therapeutics. Blunt fetomaternal consequences are ruled by pelvic haematomas, uterine rupture, prematurity, acute fetal distress, fetal injuries and in utero death. At mid and long range arise the problem of child birth way and the risk of mechanical dystocy. Cesarean is store in case of vesical and urethral injuries, or perineal injury, several pelvic fractures or in case of the pelvic belt fracture moved and not reduced, bringing to a surgical unsymmetrical pelvis. In the other cases, the obstetrical prognoses will be done after a dialogue with all medical staff and a full synthesis of the file based on the fetopelvic comparisons (obstetrics previous, clinic, fetal biometry, pelvimetry X ray).

Prenatal diagnosis of thrombocytopenia-absent radius syndrome.

Thrombocytopenia-absent radius (TAR) syndrome is an autosomal-recessive disorder characterized by a thrombocytopenia and a bilateral radial aplasia with normal thumbs. Only TAR syndrome, out of diseases which may present with radial aplasia, typically has normal thumbs. The prenatal diagnosis is rarely made. We report two observations of TAR syndrome diagnosed in utero in the sibling. The malposition of fetal hands detectable as soon as 11 weeks of gestation requires careful search for longitudinal limb defect of the forearm, especially radial ray defect. The radial aplasia is associated with numerous causes (chromosomal, teratogenic, genetic, multifactorial). The determination of fetal hematologic values revealing a thrombocytopenia allows the prenatal diagnosis of the index case of TAR syndrome.
