An additional thought:
Perhaps Jason implied "why scan the contralateral leg ASSUMING ALL PATIENTS
WILL RECEIVE ANTICOAGULATION"
I'll add my two cents and say
that not all pts with newly dx'd thrombus ARE given heparin.
(And think of the variety of reasons: medical condition,
location of thrombus, other...)
But if we do scan, and we find the other leg
is positive we then may have a few scenarios:
1) contralateral leg scenario "in or above the pop v"
Perhaps there is thrombus in the asymptomatic leg (as
has been testified to in this thread.) And it is of a greater
extent than the ipsilateral calf, now warranting anticoagulation.
(depending on your docs' protocols, which we know vary)
2)the progression scenario - in the case where no hep was
In these cases, the subsequent scan will occur at a point
in time farther along the developing medical management
pathway, and having a thorough previous will add to the picture
and assist docs in their management decision.
Maybe this post of mine is a little of topic of Jasons original
question of "Would knowing more about the other leg
affect the result of INEVITABLE anticoagulation" (how did I do
with that rephrasing), but I thought it was a fun tangent.
