“…Splenoportography: Can also be done by using CO 2 in selected patients[25] such as a patient in which portal vein imaging study for patency is inconclusive[26]. Twenty-two to twenty-five gauge needle can be used to inject CO 2 into the parenchyma of spleen.…”

Use of X-ray contrast allows us to differentiate between two or more adjacent structures on radiographic studies. The X-ray contrast agent can be the one with increase X-ray absorption, like iodine and a barium X-ray contrast agent or the one with decrease X-ray absorption like air and carbon dioxide contrast agent. Each contrast agent possesses different risks and benefits in various ways. Carbon dioxide as an intravascular contrast agent can be used as an alternative intravascular contrast agent and has superior results in some cases. In patients with renal dysfunction or iodinated contrast allergy, the use of Iodinated Contrast Agent poses the risk of considerable morbidity. Similarly, use of Gadolinium is discouraged in subject with severe renal dysfunction. Use of carbon dioxide (CO2) as an intravascular contrast, offers an alternative in such patients for certain procedures, as it is not nephrotoxic and it does not incite allergic reactions. It is inexpensive, readily available and due to its unique physical properties, it can be used to image a wide variety of vascular beds and chambers. The aim of this paper is to systemically review the current literature to describe the indications, contraindications, adverse effects, instruments, precautions, latest methodologies and data supporting for the use of CO2 as a contrast agent.

“…Today, CO 2 can be used for the imaging of shunt vessels in patients on hemodialysis [8], the wedged hepatic venography in the evaluation of portal hypertension [9], and angiography in patients with renal dysfunction due to chronic kidney disease [10]. Moreover, as the new technique to replace the standard splenic arterial portography, CO 2 wedged arterial splenoportography is introduced to visualize gastric varices associated with splenic vein occlusion [11]. Further investigations to widen the range of applications of CO 2 angiography are expected.…”

Transcatheter arterial embolization has become a common management option for intractable postpartum uterine hemorrhage. Iodinated contrast agents are commonly used for embolotherapy but cannot be used in patients with renal dysfunction or iodine allergy. A 37-year-old woman spontaneously delivered a healthy girl but developed severe postpartum uterine hemorrhage, probably due to placenta accrete. Contrast-enhanced computed tomography revealed extravasation of the iodinated contrast agent into the uterine cavity. The patient subsequently developed allergic reaction to this agent. After recovery from the allergic reaction with appropriate treatment, we performed carbon dioxide angiography and found that the extravasation originated from the right uterine artery. Embolization of the right internal iliac artery was performed, and hemostasis was verified. Based on this experience, we suggest carbon dioxide angiography and arterial embolization can be used for treating intractable postpartum hemorrhage in patients with iodinated contrast media allergy or renal dysfunction.

“…43 Although it was initially reported that indirect arterial portography would still provide a better visualization of varices, recent experimental studies with CO 2 wedged arterial splenoportography have shown promise in visualization of gastric varices associated with splenic vein occlusion. 44,45 In addition, the anastomotic site can also be evaluated with CO 2 portography in patients with a hepatic transplant (Fig 9).…”
