Abstract
This study introduces an anatomical basis for surgeries such as thoracoscopeassisted
thoracolumbar spinal anterior interbody fusion in terms of image observing
and corpse specimen anatomising. The observation of the 3-dimensional
computed tomography (CT) image indicates that segmental arteries are
visible and run in the central supersulcus of the corresponding vertebral body’s
side, while the branches are invisible. The distances between adjacent segmental
arteries in T10/11, T11/12, T12/L1, L1/2, and L2/3 are 23.35 ± 1.48, 25.61 ± 2.08,
29.12 ± 2.30, 32.53 ± 2.18, and 33.73 ± 2.29 (mm), respectively. And the
observation by the thoracolumbar spine side of the adult corpse specimens
shows that segmental arteries and veins constantly exist and run in the central
supersulcus of the corresponding vertebral body’s side; each segmental artery
has some small branches; the zone between the upper and lower segmental
arteries form a relatively non-vascular nerve safe zone, where the intervertebral
space (disc) locates. The distances between adjacent segmental arteries in T10/11,
T11/12, T12/L1,L1/2,L2/3 are 23.34 ± 0.78, 25.54 ± 0.85, 29.11 ± 1.01, 32.82 ±
± 1.28, and 33.71 ± 1.42 (mm), respectively. The safe zone, with the intervertebral
disc as the reference mark, can provide enough operation space for surgeries
like thoracoscope-assisted anterior interbody fusion and reducing damage
to blood vessels as well as surgical complications. Additionally, the arrangement
and distribution of segmental arteries can be clearly displayed on
the 3-dimensional CT image and the result is basically consistent with that of
corpse specimens. Therefore, the 3-dimensional CT image can be regarded as
the reference for video-assisted thoracoscopic surgery plans.
