What is compression of the ventral dural sac?
Flattening of the Dural sac is something that can be observed in patients who suffer from muscular atrophy of distal upper extremities. This means the Dural sac that encloses the spine is restricted and could cause many different things.
to touch the spine
The dural sac covers the spine. Typical causes of dural sac impingement typically include bulging discs, herniated discs, or osteophytes. These conditions can also affect the spinal cord.

If you have no symptoms it's just a slightly squashed intervertebral disk, if you do have symptoms it's were they're going to cut. (C5-C6 is low on your neck)
dural folds
Effacement of the anterior thecal sac refers to compression of the thecal sac in the spine due to conditions like disc herniation or spinal stenosis. This compression can lead to symptoms like pain, numbness, or weakness in the back or limbs. Treatment options may include physical therapy, medications, or surgery depending on the severity of the compression.
The dural venous sinus that contains arachnoid granulations is superior saggital sinus.
The main function of the dura mater (as with the arachnoid and pia mater) is to protect, surround, and support the spinal cord. It also forms the dural sac which extends from the foramen magnum all the way down to the coccyx. Inside this formed sac is where you'll find the arachnoid mater, subarachnoid space, pia mater, and the spinal cord/nerves/roots.
Sub dural or extra dural haematoma
Dural Sinuses
The dural fold that projects into the longitudinal fissure between cerebral hemispheres is called the FALX CEREBRI.
