A diagnosis of spina bifida is often made during pregnancy following an ultrasound examination as part of first-trimester screening.
In the open form (spina bifida aperta), the vertebral arch is split. The spinal meninges or parts of the spinal cord bulge outward. Spina bifida is visible immediately after birth. The closed form (spina bifida occulta) is often discovered by chance and may (initially) be asymptomatic. Although the vertebral arch is split, the meninges or spinal cord are generally not affected.
Symptoms
The symptoms associated with spina bifida can vary widely. Whether and to what extent the malformation affects the baby depends on its location and severity;
- Occurrence in the thoracic or lumbar spine
- Protrusion of portions of the spinal cord and
- Nerves on the outside.
