[Magnification technique in peripheral angiography (author's transl)].

Fourteen exactly similar conventional and magnified serial angiograms were compared and the advantages and disadvantages of magnification angiography are discussed. Particular attention was paid to exact comparability of the series in order to make the analysis valid. In three patients small end-vessels and collaterals were visible on the magnification angiogram which could not be seen on the ordinary series even in retrospect. Macro-angiography was also valuable in cases of microsurgery, both before and after operation. Considering the well-known disadvantages of magnification angiography, such as increased radiation and cost, its use appears to be indicated only for the elucidation of special problems.
