hi eric,

an often overlooked/forgotten possibility is endofibrosis of iliac
arteries which tends to occur in female endurance athletes

here's a good reffrence article:

external iliac endofibrosis in endurance athletes: a novel case in an
endurance runner and a review of the literature.
S.J. Ford, A Rehman and A.W. Bradbury
Eur J Vasc Endovasc Surg 26, 629-634 (2003)

we use an extended treadmill protocol, carefull duplex imaging (for long
smooth sublte changes in EIAs) and post exersice waveform analysis to
identify these folks. we have a small series of 5-6 patients here who have
undergone patchgraft angioplasty with resolution of sxs. and normalization
of post exersice findings on f/u exams.

remeber Bernoulli does not lie! if you feel there was a good treadmill
exam and her pressures really did drop, then i bettcha there is a vascular

hope that helps!
