Description
Purpose: To determine the optimal dose of nicardipine (NCR) for enhancement of indirect portography. Methods: Forty-eight patients underwent conventional film indirect portography via the superior mesenteric artery (SMA) first without and then with preinjection of 1/64-2 mg of NCR into the SMA. Results: NCR (1/8-2 mg) shortened the arterial phase to 50% and the portal appearance time to 60% of control without reflux of contrast medium into the aorta. Portal enhancement was excellent at doses of 1/32 mg or more. Blood pressures and pulse rate showed no significant change at 1/4 mg or less. Conclusion: NCR (1/8-1/4 mg) into the SMA is the optimal dose for achieving sufficient contrast enhancement on indirect portography while reducing the transit time of contrast medium and minimizing effects on the systemic circulation
