Overview
Echocardiography
- Compared with the general population, the prevalence of congenital heart disease in newborns with myelomeningocele is increased , however critical disease is uncommon.[1]
- When the myelomeningocele is prenatally diagnosed, antenatal cardiac screening is complete and normal, and the newborn is clinically well, preoperative echocardiography is unnecessary.[1]
Ultrasound
Study of choice
- Ultrasound is the imaging modality of choice for characterisation of the open spina bifida spinal lesions.[2]
- On two and tree-dimensional ultrasound, spina bifida is characterized by:[3]
- Vertebral defect
- Splayed vertebral pedicles
- Disrupted vertebrae
Sequence of Diagnostic Studies
The ultrasound must be performed when a positive alpha-fetoprotein is detected in the triple screening test between the 15th and 20th week of pregnancy to confirm the diagnosis.[4][5][6][7]
