I never thought of that. Once the jugulars are treated, would the condylar veins no longer be contributors in that way? There is still going to be occasional reflux such as valsalva. My first thought was that these veins could be treated with coil embolization which would get rid of them if sufficient flow was restored through other veins and these were a continuing problem. But it's hard to imagine wanting to get rid of a drainage route.
yes, i tend to agree with you that collaterals are good. Here is what my new mentor has taught me recently:
FLANK FIBROSIS IN MS OF THE SPINAL CORD
· Post mortem studies for MS typically traced fibrous wedges invading the spinal cord’s sides
· No MR expert seems ever to have focused on this point.
Such lesions result in front-to-backwards or longitudinal displacement of the spinal cord. How can these findings be accounted for, through either venous stasis or reflux, relative to CCSVI?
HOW TO PUT CCSVI AND CEREBRAL OR SPINAL MS FINDINGS IN CONTEXT?
This might be done by identifying,
· in MS of the brain, the compartmentalization of venous reflux via or from internal jugular and deep cervical veins to cerebral lesion veins
· in MS of the spinal cord, the compartmentalization of venous reflux from engorged prevertebral veins in the direction of the specifically damaged parts of the spinal cord.

franz, what a great opportunity to have you review my paper and make such important recommendations and corrections!!!
Thank you so much.
Yes, I would like to discuss these phasic narrowing. I fail to see how we can treatment, by interventional techniques. There is never any resitance to balloon inflation and treatments such as surgical releases seem so complicated to me and how can we prove that these phasic narrowings can be clinically impoortant.
I look forward to your educating me on the value of these small veins in the back of the neck
Best wishes for new year

Sal, determining the phasic narrowings' relevance is only possible in elucidating their impact on related lesion developments.
Routine MRI, MRV and even functional IVUS tools hardly enable to this. The phenomena to be studied are probably all too short-lived and exceptional.
The ordinary difference between deep cervical vein and vertebral vein is well shown on page 220, the potential caliber of the deep cervical vein on page 53(-57) of the first volume of Pernkopf E. "Atlas der topographischen und angewandten Anatomie des Menschen", München/Berlin 1963 - and already in considering the diameters of the posterior condylar and mastoid emissary vein shown on Fig. 1 C and on Fig. 3 of Schelling F. "Die Emissarien des menschlichen Schädels", Anat(omischer) Anz(eiger) 1978; 143: 340-382).

subject Condylar veins
hide details Jan 1
For the past 100 procedures I begin the venography in the transverse sinus. I have seen condylar veins that are huge, 8mm with many large tributaries. But I have recognized no trend in response, in presentation, or in type of disease. I unfortunately do not have mr data on all of them. What do you think I should be looking for?
Happy new year again my friend
