[Carbon dioxide angiography: technique and indications].

Area of Science:

• Vascular imaging
• Interventional radiology
• Medical diagnostics

Background:

• Angiographic procedures are increasingly common.
• A need exists for alternative intravascular contrast agents due to contrast allergy and renal insufficiency.
• Current contrast agents pose risks for certain patient populations.

Purpose of the Study:

• To evaluate carbon dioxide (CO2) as an alternative intravascular contrast agent.
• To assess the safety and efficacy of CO2 in diagnostic angiography and interventional procedures.
• To explore CO2 use alone or in combination with other contrast media.

Main Methods:

• Thirty patients underwent diagnostic angiography and interventional procedures using CO2.
• CO2 was administered either solely or in conjunction with Gadolinium or non-ionic contrast media.
• Patient outcomes and procedural success were monitored for complications.

Main Results:

• The use of CO2 as an alternative contrast agent was performed in thirty patients without any reported complications.
• CO2 provided sufficient contrast for diagnostic angiography.
• CO2 was effective in vascular interventional procedures.

Conclusions:

• Carbon dioxide (CO2) is a safe and effective alternative intravascular contrast agent.
• CO2 can be utilized in patients with contrast allergies or renal insufficiency.
• CO2 offers a viable option for enhancing diagnostic angiography and interventional procedures.
