Vascular Intervention Carbon Dioxide Digital Subtraction Angiography for A Renal Artery Stent Placement 1
MATERIALS AND METHODS: Seventeen hypertensive patients with renal ostial stenosis were evaluated and underwent stent placement with use of CO, digital subtraction angiography (DSA). Besides hypertension, 11 patients had decreased renal function, three had iodinated contrast material allergy, one patient had both, and two had neither. Supplemental iodinated contrast material (25 mL or less) was ...
متن کاملThe cerebral effects of carbon dioxide during digital subtraction angiography in the aortic arch and its branches in rabbits.
PURPOSE We studied the neurotoxicity of carbon dioxide as a contrast agent in the central nervous system by performing CO2 digital subtraction angiography (DSA) in the aortic arch and its branches in experimental animals. METHODS Twenty-five rabbits underwent intraarterial CO2 DSA while under general anesthesia, during which 50 angiograms were obtained after administration of 3 mL/kg CO2. MR ...

OBJECTIVE We prospectively compared patients' tolerance for and the usefulness of carbon dioxide (CO2) with iodinated contrast material in the study of lower limb arteries in 30 patients. SUBJECTS AND METHODS We systematically performed digital subtraction angiography with electronic injection of CO2 (injection average, 330 ml) and digital subtraction angiography with iodinated contrast mater...
متن کاملCarbon Dioxide Angiography: Scientific Principles and Practice
Carbon dioxide (CO2) is a colorless, odorless gas which occurs naturally in the atmosphere and human body. With the advent of digital subtraction angiography, the gas has been used as a safe and useful alternative contrast agent in both arteriography and venography. Because of its lack of renal toxicity and allergic potential, CO2 is a preferred contrast agent in patients with renal failure or ...
