IntroductionThe usefulness of carbon dioxide (CO{sub 2}) gas digital subtraction angiography (DSA) has been reported for patients with renal insufficiency and allergy to iodinated contrast agents. However, CO{sub 2} gas cannot replace the iodinated contrast agent in all cases owing to some disadvantages. We describe balloon-occluded CO{sub 2} DSA (B-CO{sub 2} DSA) as an improved CO{sub 2} DSA procedure for interventions in the internal iliac artery (IIA) region and compare the quality of images obtained using conventional CO{sub 2} DSA and B-CO{sub 2} DSA.Materials and MethodsB-CO{sub 2} DSA-guided embolization was performed for one case of genital bleeding with an acute anaphylactic reaction to the iodinated contrast agent and for three cases of type II endoleaks after endovascular abdominal aortic aneurysm repair with renal dysfunction. A 9-mm occlusion balloon catheter was placed just after the orifice of the IIA. Then, 10–15 ml of CO{sub 2} gas was injected manually via the catheter with and without balloon occlusion. The quality of sequential digital subtraction angiograms was analyzed based on a scoring criterion.ResultsIn all four cases, image quality was improved with B-CO{sub 2} DSA; the poor quality of images without balloon occlusion was because of reflux of the CO{sub 2} gas.ConclusionsB-CO{sub 2} DSA improves the image quality of CO{sub 2} DSA in the IIA region and is useful for vascular intervention. Level of Evidence: Level IV.
