Results
99 adults (74 males:25 females, mean age =72 with age range of 41-95) with 119 CO2 lower limb angiography were included. There were 36 studies in CO2-only group and 83 studies in CO2 + ICM group with ICM used purely for below knee run-off arteries. Median dose of ICM used was 10ml (range 3.5-32ml) in diagnostic angiograms, and 15ml (range 5-55ml) where there was intervention. The mean diagnostic quality of below knee arteries in the CO2-only group is poor at 1.75 / 5 based on Likert scale which was improved to 3.16 / 5 (+80.16% improvement) with the addition of ICM for below knee runs (p <0.0001) (Table 1). There was no significant difference between CO2-only and CO2 + ICM groups for above knee images.
Renal function was available for 21 inpatient diagnostic angiograms from the CO2 + ICM group and showed no significant difference in the mean creatinine levels pre and post procedure (Table 2).
