Introduction: Vaginal delivery after caesarean section (VBAC) is recommended, but the rising rate of uterine rupture calls into question the safety of this practice.
Aim: To identify risk factors for uterine dehiscence and rupture.
Methods: This was a prospective, analytical and descriptive observational study, carried out in a tertiary care maternity. We included all parturients with one previous caesarean section undergoing trial of labor. We assessed the quality of the uterine scar which was evaluated after delivery.
Results: We included 300 patients with one previous caesarean section undergoing trial of labor. The trial of labor was successful (vaginal delivery) in 50.7% of cases. The uterine scar, assessed after delivery, was of good quality in 79% of cases. We noted 7 cases of uterine rupture, i.e. 2.3% of cases, and dehiscence in 56 patients, i.e. 18.6% of cases. Parity, conditions of previous caesarean section (programmed or emergency) and interpregnancy interval were significantly related to the labor outcome (p=0.004, p=0.001 and p=0.135 respectively). The occurrence of rupture or dehiscence was not significantly related to macrosomia, defined as a neonatal weight greater than 4000g (p=0.135).
Conclusion: Knowing the risk factors for uterine dehiscence and rupture would enable the obstetrician to properly assess the situation in order to make the correct decision and avoid neonatal and maternal complications.

Background: A ten-group classification system of caesarean section was proposed by Michael Robson in 2001. It is helpful in comparing the rates of caesarean section between hospitals. The objective of this study was to determine the caesarean section rates to analyse trends of caesarean section and classify according to Robson's categories.

Background: Placenta accreta spectrum (PAS) disorder is a fatal condition responsible for obstetric haemorrhage, which contributes to increased feto-maternal morbidity and mortality. The main contributing factor is a scarred uterus, often from a previous cesarean delivery, myomectomy, or uterine instrumentation. The occurrence of PAS in an unscarred uterus is extremely rare, with only anecdotal cases reported so far in the literature.

Placenta accreta represents a spectrum of adherent placental anomalies and is an atypical invasion of the placenta. The major predisposing factor is a prior cesarean delivery. Placenta previa is considered an additional risk factor.

Glanzmann thrombasthenia (GT) is an autosomal recessive platelet functional bleeding disorder caused by mutations in the ITGA2B or ITGB3 genes, often presenting as mucocutaneous bleeding. GT typically presents in infancy, but this study reports a rare case of neonatal presentation in a female infant born to consanguineous parents. The mother, a 27-year-old woman with a family history of GT, presented at 36 weeks gestation for an elective cesarean due to a breech presentation.
