Interventions

DIAGNOSTIC_TESTUltrasound between 6+0 and 6+7 weeks of pregnancy - With Isthmocele

Location of implantation of the GS (gestational sac) amended to Naji et al, defined as 3 possible implantation sites: (A: fundal, B: anterior, C: posterior) Size of isthmocele: * Depth of isthmocele * Width of isthmocele * Circumference of isthmocele Distance between isthmocele and outer cervical os (measured with the trace line) Distance between CS scar and outer cervical os (measured with the trace line) Size of gestational sac Measurements of the isthmocele size / circumference / distance between isthmocele / CS and outer cervical os

DIAGNOSTIC_TESTUltrasound between 6+0 and 6+7 weeks of pregnancy - Without Isthmocele
