[Obstetrical outcome and risk of uterine rupture following a caesarean section before 32 weeks]. / Modalités d'accouchement et risque de rupture utérine après césarienne réalisée avant 32 semaines d'aménorrhée.

OBJECTIVE: Our aim was to evaluate the subsequent obstetrical outcome and rate of uterine rupture following a caesarean section before 32 weeks of gestation. PATIENTS AND METHODS: A retrospective cohort study of 200 consecutive women with a prior caesarean section performed between 25 and 32 weeks were contacted by questionnaire or followed through medical charts to determine the subsequent mode of delivery. RESULTS: Two hundred caesarean section were performed between 25 and 32 weeks from January 1997 to March 2000. Thirty-nine patients (19.2%) were lost to follow-up. Seventy-one patients had a subsequent delivery. Thirty-two attempted vaginal birth and the success rate was 87.5%. Thirty-nine patients had a subsequent caesarean. One case of uterine rupture occurred before labour at 31 weeks (1.4%, % IC 95% [0.25; 7.56]). CONCLUSION: After a previous caesarean delivery before 32 weeks, a trial of labour may be proposed when obstetrical conditions are optimal. However, uterine rupture may occur prior to labor.

[Beta-thalassemia and pregnancy. Apropos of 2 cases]. / Bêta-thalassémie majeure et grossesse. A propos de deux cas.

Homozygous beta-thalassemia is a severe, transfusion dependent anaemia that also causes infertility. Preimplantation genetic diagnosis is possible. Very few pregnancies are reported among such patients. They have a very high obstetrical risk and a pluridisciplinary follow is necessary.
