ANGIOGRAPHY WITH CARBON-DIOXIDE IN COMBIN ATION WITH VASCULAR INTERVENTION

Within the last 18 months we examined 130 patients with known complica tions or contraindications using iodinated contrast media for angiogra phy by using carbondioxide as contrast agent in digital subtraction an giography technique, These were diagnostic pelvis-leg angiographies (n = 106) with simultaneous consecutive interventional radiologic therap y in 68 cases. In 19 dialysis access fistulas 11 angioplasties were pe rformed in the same session, In 5 cases of renal allografts no interve ntional radiologic therapy was necessary, For CO2 application an elect ronic controlled special injector was used, Carbondioxide has a number of advantages: no adverse reactions, nonallergenic and can be used se veral times without increasing risks and is cost-saving, CO2 angiograp hy is a sensitive method, for detection vessel wall processes below th e diaphragm, It can replace conventional angiography.
