[Documentation of hemodynamic parameters in collateral circulation].
By adding phase-differences of serial angiographies in contrasting colours, combination-images are produced, which show the functional way of perfusion without loosing significant morphologic details. Using this technique it is possible to document the direction of blood flow and other hemodynamic parameters and to estimate the average flow rate in a single picture. Finally own results in patients with obliterations and collaterals are given and discussed.
