OK, a truncular vein must be a main large vein, like the jugular or azygous. Smaller veins flow into truncular veins. Have I got this right ?

Truncular means 'of the trunk' - as in the trunk of the body - essentially, from the throat to the belly. Truncular veins would be in this area - i.e. Vena Cava, Jugular Vein, Pulmonary vein, etc.

I just did a quick google on the word truncular and I found this old thread...
My problem is Im married to a gp and she is so nit picky. i say "ccsvi is truncular and so congenital" and she says "truncular doesnt mean always congenital" and the conversation stops. Seems to me I went through this months ago but I cant find a reference to send her. Anyone?

I found this doing a google search; Truncular refers to vascular lesion that develop later in the embryo development stage so it doesn't refer to the vessel size but only to the vessel origin.
"The current classification scheme divides venous malformations into two broad categories: truncular and extratruncular.
Extra-truncular venous malformations originate from
remnants of primitive vessels early in development
and tend to be dysplastic and diffusely infiltrative.
Truncular venous malformations originate from a
differentiated vascular truncus at a later stage of
development and are more defined. These two
malformation types tend to have very different
clinical presentations. Truncular venous malformations often have very
impressive cutaneous manifestations in the form
of prominent varicosities and limb swelling. This
is typically caused by retrograde flow of venous
blood in the dilated valveless venous channels of
the malformation. When the malformation is focal
and small, the degree of reflux is minimal and
patients usually do not have any significant
symptoms other than some cutaneous varicosities.
Larger focal malformations can cause significant
reflux and symptoms are almost entirely related
to this process. In the lower extremity, focal
truncular malformations frequently connect to
both the deep and superficial venous system. In
this setting, retrograde flow, or reflux, from the
deep system into normal superficial veins is the
result."
