Purpose:
The aim of this study was to assess the utilisation of carbon dioxide arteriography, performed with a simple injection system, as the imaging technique of choice in patients with chronic renal failure.
Methods:
Patients with chronic renal impairment who required arterial imaging or intervention were recruited for carbon dioxide angiography. Demographic data were prospectively recorded and pre- and post-arteriogram renal function was quantified. Radiographic images were graded by an independent radiologist.
Results:
Twenty-eight patients underwent renal or aorto-femoral studies with only one failure. There were no cases of contrast-induced nephropathy. Twenty-two of the films (79%) were graded as excellent or good, four as acceptable and two were considered to be poor (non-diagnostic).
Conclusions:
This study has demonstrated that carbon dioxide angiography is a safe and clinically effective procedure in patients with chronic renal failure.
