In 10 laboratory swines we investigated an automatic gas injector for angiography and angioscopy that allows the reproducible injection of variable quantities of gas, with variable pressure and injection times. With small volumes of carbon dioxide (CO; 10-50 cc; 850-1250 mbar application pressure) a column of gas can be created, which facilitates digital subtraction angiography comparable to conventional contrast media (CM) or an angioscopy within a sufficiently bloodless visual field. A total of 93 of 127 angiographies of the abdominal aorta and 49 of 57 angiographies using CO were successful. A lack of success was obtained in selective angiographies. The use of injector-controlled CO application is an alternative for angiography in patients who are at increased risk using conventional CM. This technique was an unexpectedly excellent method of performing a renal venogram as well as a fast splenoportogram. Petcutaneous transluminal CO angioscopy affords a bloodless inspection of the aorta and side branches for a period of several minutes. [ABSTRACT FROM AUTHOR] |
