RESUMO
Objective To investigate the arterial blood supply of the pancreas head and provide a theoretical basis for the gastroduodenal artery reconstruction in pancreatic transplantation(PT).Methods Photograms of digital subtraction artery(DSA)which performing on 300 patients were analyzed to recognize the aberrations of arterial blood supply of pancreatic head.Results In 300 DSA photograms,the gastroduodenal artery(GD.a)was identified in 131 cases,and the anterior superior pancreaicduodenal artery(ASPD.a)and posterior superior pancreaicduodenal artery(PSPD.a)in 79 cases.The rate of aberrant origin of pancreatic transverse artery(PT.a)from GD.a was 12.98℅.There are some minor sources of blood supply to the pancreas head from GD.a.The rate of absence of an ASPD.a-AIPD.a anastomosis and PSPD.a-PIPD.a anastomosis was 15.19℅and 24.05℅,respectively.Conclusions The reconstruction of gastroduodenal artery can ensure a complete blood supply to the pancreatic head and duodenum in PT.
