title: Sonographic diagnosis of limb reduction defects in a fetus with haemoglobin Bart's disease at 12 weeks of gestation.
abstract: Limb reduction defect is a rare event but is found in eight per cent of fetuses affected by haemoglobin Bart's disease. We present a case of haemoglobin Bart's disease with terminal transverse limb reduction defects of all four limbs diagnosed by abdominal ultrasound examination at 12 weeks of gestation. The pregnancy was terminated by suction curettage. Just prior to the procedure, transabdominal needle embryoscopy was performed and this confirmed the sonographic diagnosis. The present case demonstrates the need and feasibility of a detailed anatomic survey of a fetus affected by haemoglobin Bart's disease at 12 weeks. This is particularly relevant if the patient is considering the option of intra-uterine therapy.
