Abstract:
Objective To investigate the feasibility of gadopentetate dimeglumine as contrast agent for arteriography and interventional procedures.Methods Nine patients received gadopentetate dimeglumine as contrast agent during interventional procedures. Gadopentetate dimeglumine was used in 2 patients with contraindications to iodinated contrast media. In addition to the standard injection sequences with iodinated contrast media, arteriograms were obtained after administration of gadopentate dimeglumine in seven patients. Diagnostic arteriographies were performed in thoracic aorta, common carotid artery, bronchial artery, intercostal artery, hepatic artery, iliac artery and uterine artery. The doses of gadopentetate dimeglumine used in this series were≤0.3 mmol/kg. Vital signs and arterial oxygen saturation were monitored during the procedures. The blood and urine routine examinations, the hepatic and renal functions tests were done after the procedure. Results There were no significant differences between the gadopentetate dimeglumine and the iodinated contrast media examinations for illustrating the main trunk of these arteries. Angiograms obtained with the iodinated contrast media appeared to be better than that of with gadopentetate dimeglumine for visualizing the distal branches of these arteries and the tumor stain. The interventional procedure was completed successfully in the two patients using gadopentetate dimeglumine alone. No patient suffered from complication related to the use of gadopentetate dimeglumine, and also no worsened renal function was shown after the procedure. Conclusions Diagnostic arteriograms can be achieved safely and successfully by using gadopentetate dimeglumine, especially in patients with allergy to iodinated contrast media and chronic renal insufficiency.
