胰头动脉血供与胰腺移植时胃十二指肠动脉重建的研究

目的:了解胰头动脉血供及其变异情况,为胰腺移植时胃十二指肠动脉(GD.a)的重建提供理论依据。方法:回顾分析300例胰腺动脉造影片,分析胰头动脉血供的变异情况。结果:300例造影中, GD.a显影为131例,能辨认胰十二指肠上前动脉 (ASPD.a)和胰十二指肠上后动脉(PSPD.a)者均有79例, GD.a可以发出供血于胰体尾部的胰横动脉（PT.a),其变异率为12.98℅。此外,GD.a尚发出小分支供血于胰头20.61℅。ASPD.a-AIPD.a,PSPD.a-PIPD.a动脉弓的缺失率分别为15.19℅和24.05℅。结论:重建胃十二指肠动脉可以保证胰头十二指肠完整的血供。

Study of the arterial blood supply of the pancreas head and the gastroduodenal artery reconstruction of pancreatic graft

Abstract: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.
