infant congenital muscular torticollis link to CCSVI?
Posted: Mon Dec 06, 2010 2:07 pm
I have been trying to sort out if there could be a link between CCSVI and congenital muscular torticollis of infancy. This is when the sternocleidomastoid muscle has a fibrosis in it and the baby holds its neck in a twisted position to the left (or the right) and rotated down to the side. Often it is considered a result of trauma during the birth but in some cases it runs in families and may be due to another cause. In my family, two of my three children were affected by this (thankfully it resolved with stretching during infancy).
Here is something I've found:

Any thoughts?

IJV obstructed proximal to the subclavian vein - I haven't got access to the full document, but what sort of obstruction was this? Could it have been obstructed from birth, undiscovered at the time of the treatment? This is where many CCVSI obstructions are found.Clin Orthop Relat Res. 1992 Feb;(275):258-62.

Abstract
An extremely rare vascular complication, carotid artery aneurysm, developed 60 years after a torticollis operation. The patient's internal jugular vein was completely obstructed proximal to the subclavian vein. There was an associated incomplete obstruction of the ipsilateral common carotid artery on the right aspect of the neck--the site where resection of the whole sternocleidomastoid muscle had been performed when she was one year old. The patient had audible bruits over the right common carotid at the base of her neck but no signs of occlusive cerebrovascular disease. The diagnosis was made mainly with use of technetium radionuclide angiography. To the authors' knowledge, this is the first such report in the English or German literature.

I can't find out which veins they're talking about here. Could an obstructed venous tree, not as a result of trauma but of inherited internal jugular obstructions, lead to the development of a sternocleidomastoid mass? Either way, intravascular clotting doesn't sound good either.Pathophysiology
An end-arterial branch of the superior thyroid artery supplies the middle part of the sternocleidomastoid muscle. Obliteration of this end artery may be responsible for the development of muscle fibrosis. As an alternative, primary trauma that temporarily and acutely obstructs the veins may lead to intravascular clotting in the obstructed venous tree. In infants, this clotting is evidenced by the development of a sternocleidomastoid mass, which eventually disappears and is replaced by fibrous tissue.
Any thoughts?
