Analysis of development of pancreatic arteries in selective arteriography via abdominal arteries

Abstract

Objective To analyze the characteristics and rules of development of pancreatic arteries in selective arteriography via abdominal arteries to provide basis for arterial choice in arterial infusion (AI) for treatment of pancreatic diseases such as severe acute pancreatitis etc. Methods The data of 203 cases undergoing selective arteriography via abdominal arteries in our hospital from May 1981 to August 1999 were classified and sorted to calculate the positive rates of main arteries supplying the pancreas. Results In 119 cases undergoing selective celiac angiography, positive rates of the superior pancreaticoduodenal artery (SPD.a), anterior and posterior pancreaticoduodenal arcades and dorsal pancreatic artery were 32%, 16% and 27.7%, respectively. However, only one inferior pancreaticoduodenal artery (IPD.a) was developed. In 55 cases undergoing superior mesenteric angiography, only IPD.a was developed and its positive rate was 40%. In 18 cases receiving celiac and SM.a co-angiography, positive rates of SPD.a, two arcades, dorsal artery and IPD.a were 55.6%, 27.8%, 61.1% and 27.8%, respectively. Conclusions According to these results, we can conclude that the positive rate of pancreatic arteries by co-angiography is higher than that by single-artery angiography.
