Intraarterial tolazoline in angiography of the foot

Foot angiography was performed in 32 diabetic patients with and without intraarterial injection of tolazoline (Priscoline). The angiographic quality was improved with tolazoline, manifested as an increased flow rate with acceleration of the arteriovenous transit time, a higher incidence of complete arterial filling with contrast medium in clinically important regions, and considerably longer arterial segments demonstrated within defined regions of measurement.
