[Diagnostic value of digital subtraction angiography in chronic venous insufficiency]

The first 117 investigations in chronic venous insufficiency by means of the technique of digital subtraction angiography (DSA) are reported. According to our experiences hitherto made this technique with peripheral intravenous injection of contrast remedies is excellently suited for the phlebography of the pelvic and vena cava regions as well as of the region of upper arm and shoulder, not so much, however, for the phlebography of the leg. By decrease of the concentration of the contrast remedy and the total quantity of the contrast remedy a reduction of the patient's stress and the risk of the examination is the result.
