Introduction: Cervico-isthmic pregnancy is rare, and serious because of its hemorrhagic complication. Its management varies according to the teams. Observation: We report a case of cervico-isthmic pregnancy on a cesarean scar. This is a 35-year-old, G2P2, who consulted for bleeding from the 1st trimester of pregnancy. The clinical examination found a minimal uterine bleeding. The diagnosis was made by a vaginal ultrasound which found a cervico-isthmic implantation of the pregnancy on the caesarean scar. A protocol of Mifepristone and Misoprostol followed by administration of a single dose of 1 mg/kg of Methotrexate was performed. Cure was obtained 1 month after treatment by negativation of plasma HCG. No bleeding complications were noted. A follow-up ultrasound performed 2 months later showed a uterine vacuity and the presence of an isthmocoele. It was in fact a pregnancy that had implanted in the isthmocoele. Conclusion: Cervico-isthmic pregnancy is rare. His treatment is not codified. Drug management was successful.

Introduction: OVT is rare, with an incidence of 0.05% to 0.18% and occurring preferentially in postpartum period. Any delay in management may compromise the patient's vital prognosis. Observation: We report a case of a 34year-old patient, G2P3, who delivered twins by cesarean section at 39 weeks of amenorrhea. She presented abdominal pain and fever on the 4 th day of postpartum. Biological tests showed a biological inflammatory syndrome and a positive blood culture with gram-positive Staphylococcus. After 72 hours of antibiotics with no clinical or biological improvement, a CT scan revealed a 12 mm thrombus in the lumen of the right ovarian vein's connection to the inferior vena cava. Antibiotic treatment was continued, associated with an anticoagulant. The evolution was been favorable. Conclusion: Rare and serious pathology, the diagnosis is made using medical imaging. The outcome is generally favorable with antibiotic therapy and anticoagulant therapy.
