[Hemodynamic evaluation of extra-anatomic revascularization of the aorto-iliac sector]
Arterial flow pressure were recorded from 24 extraanatomic bypass (5 axillo femoral, 8 bifemoral and 11 femoro femoral). A significant flow increase was found in the donor's limbs. On the contrary it returned to basal levels when they were temporary occluded. These results confirm the positive outcome of these operations and the inexistance of "steal syndrome" in patients without stenosis in the donor arteries. Hemodymanic studies referring to blood velocity as an important antithrombogenic factor have been taken into consideration.
