The aim of the study is to elaborate on the understanding of the application of the CO2 angiography in obtaining quality imaging of infrapopliteal diseased arteries by digital subtraction CO2 angiography, and angioplasty using the automated Angiodroid CO2 injector® (primary outcome). This is a retrospective observational non-randomized study that included 23 patients of critical LL ischemia having infrapopliteal disease alone or combined with the femoropopliteal disease along with typical renal impairment. Carbon dioxide digital subtraction angiography (CO2 DSA) was used for all the patients and the outcomes were subjected to the comparison by iodinated contrast by an operator. The study included 17 female and 6 male subjects. The age group of the patient was between 48 years and 78 years. The mean age was 61.8 ± 11.1 years. The quality of the images obtained from the CO2 DSA method adopted was categorized as: good images (9) 39%, Accepted (8) 34%, and bad (6) 26% images. No complication from CO2 injection occured for the patients, while leg pain was recorded in 4 patients during the CO2 injection (17.3%). The trial outcome elaborated and supported the safety of using CO2 angiography in the diagnosis and management of critical LL ischemia with infrapopliteal disease.
