A Caesarean scar defect, also called an isthmocele, is a gap or niche that can form in the uterine wall at the site of a previous caesarean section scar. It may cause symptoms such as prolonged spotting after periods, pelvic pain, or, in some cases, may be linked to difficulty conceiving or an increased risk of complications such as Caesarean scar pregnancy. Diagnosis is usually made with ultrasound, sometimes combined with hysteroscopy. Not all scar defects need treatment; management depends on symptoms, defect size, and fertility plans, and may range from monitoring to surgical repair.
Also known as: isthmocele, niche in caesarean scar
