Priscoline and epinephrine in selective pancreatic angiography: a comparison study using high pressure injection, Valsalva maneuver and geometric magnification
IF Hawkins Jr, JV Kaude and A MacGregor
The value of selective, high injection rate, pancreatic pharmacoangiography
was assessed in 114 patients. Opacification of the pancreas was graded on a
0-4+ scale. Selective injection of gastroduodenal and small pancreatic
arteries gave the best results, 3.7+. Celiac injection rating without drugs
was 0.9+, with epinephrine 2.2+, and with Priscoline 2.7+. Average ratings
of hepatic artery injections were 2.6+ with epinephrine and 3.0+ with
Priscoline; splenic artery injections were 2.5+ and 3.5+, respectively.
Although superselective injection was possible in only 50% of the cases,
addition of epinephrine and Priscoline resulted in an average grading of
3.4+ (yielding a preoperative diagnostic accuracy of 94%).
