Abstract EN
Epidural blocks have been used extensively in infants.
However, little histological information is available on the immature neural-dural transition.
The neural-dural transition was histologically investigated in 12 late-stage (28–30 weeks) fetuses.
The dural sheath of the spinal cord was observed to always continue along the nerve roots with varying thicknesses between specimens and segments, while the dorsal root ganglion sheath was usually very thin or unclear.
Immature neural-dural transitions were associated with effective anesthesia.
The posterior radicular artery was near the dorsal root ganglion and/or embedded in the nerve root, whereas the anterior radicular artery was separated from the nearest nerve root.
The anterior radicular artery was not associated with the dural sheath but with thin mesenchymal tissue.
The numbers of radicular arteries tended to become smaller in larger specimens.
Likewise, larger specimens of the upper thoracic and lower lumbar segments did not show the artery.
Therefore, elimination of the radicular arteries to form a single artery of Adamkiewicz was occurring in late-stage fetuses.
The epidural space was filled with veins, and the loose tissue space extended ventrolaterally to the subpleural tissue between the ribs.
Consequently, epidural blocks in infants require special attention although immature neural-dural transitions seemed to increase the effect.
