Investigation of Deviation of the left Vena Sinus Transversus

Situation before second surgery at 27-10-2000 (contrast fluid applied) comparing right and left Vene Transverse Sinus

(Neuroangio.org: The Transverse Sinuses are often asymmetric. The left is more hypoplastic then the right. (Pulsations of the right atrium are thought to be responsible for

a larger capacity of the right jugular system. The jugular foramen on smaller side is correspondingly small as well, helping to distinguish developmental hypoplasia from

acquired thrombosis.) Both Transverse Sinussen are functioning (circles on the left and right side of the images above). The cyst however might press a little on the left

vene Sinus Trasnversus as well. Both the vene Transverse Sinussen are functioning well, although the cyst might press a little on the left Vene Transverse Sinus.

Situation after second surgery at 13-04-2001 (no contrast) comparing right Vene Transverse Sinus (missing left one) and vene diaviation left.

Only the right Vene Transverse Sinus is working. There is flow inside the cyst (connection cisterna magna) some liquor got outside the membrame near the cranio-opnening

Situation after second surgery at 13-04-2001 (no contrast) comparing right Vene Transverse Sinus (missing left one) and vene diaviation left.

Left Vene transverse Sinus is lacking in Fuction as also Dia Sana scans were indicating as well, and another compensating drainage (vene deviation) appeared instead for.

One part of the artifact has a round top-shape. Also some kind of strap is attached, there are also MRI 2007 scans showing this ‘extinction artefact’.

Image distortion right under the skull. Blood remains traces of local surgery. Start liquor flow through left Vene Sinus

Transversalis. As already clear

at the MRI of

2001 only the

right Vene Sinus

Transversalis is

functioning.

Apparently the

left Vene Sinus

Transversalis is

missing, while

october 2000 it

was still present

and visible

functioning on

the MRI scan.

The Dia Sana MRI

scans 2016 point out

that the left Vene

Sinus Transversalis

is missing. Also the

V. Sinus Rectus

seemed to be cut of

from functioning

maybe in favor of

the vene diavition in

drainage function.

The scan image in

the middle makes

also the indication..

And two pieces of

special foreign body

materials were

placed. One in the

tooth (jaw) and one

in the neck,

This too much for

being an accident/

?

Ones series AZ Niklaas MRI scan is confirming the Vene diaviation as to

be seen at the Dia Sana scans in initiation. For making such a deviation

work, the Vene Transverse Sinus was cut away and also the Vene Sinus

Rectus was cut off to function. But for treating the cyst making only a

window-opening was needed between the wall of the sub-arachnoid

cyst and the Cisterna Magna. Making the experimental drainage also

caused leaking of brain-liquor over due time I think seen the images.

Image distortion starts near C4

OUTSIDE the vertebral and

then goes upward in the neck .

The distortion is at two (X)

spots at its strongest with a

lesser distortion in between.
