摘　　要：目的 探讨重症急性胰腺炎区域灌注治疗供药动脉的理想选择.方法 对45例重症急性胰腺炎患者采用区域动脉灌注治疗.依据动脉造影显示血供能覆盖整条胰腺及最大限度提高胰腺组织药物浓度作为原则选择供药动脉,最终以胰腺动脉造影作为客观依据.结果 （1）全组除l例因动脉变异而选择肠系膜上动脉作为供药动脉外,其余44例均选择胃十二指肠动脉.（2）脾动脉造影显示,流经脾动脉的血流主要供应脾脏,胰腺获得灌注的区域仅限于部分胰尾.（3）腹腔干动脉造影显示,胰腺组织虽能获得全部灌注,但有相当部分的血流经脾动脉流向脾脏、经肝固有动脉流向肝脏,致使药物利用度不高.（4）胃十二指肠动脉造影显示,胰腺组织获得全部灌注,而且含有药物的血流几乎全部流向胰腺组织,未流向非靶向器官,药物利用完全.结论 胃十二指肠动脉是供药动脉的理想选择.区域动脉灌注仍应先行常规的胰腺动脉造影.Objective To explore the ideal choice of feeding artery which is used for regional arterial infusion （RAI） in severe acute pancreatitis. Methods Forty-five patients with SAP were treated with RAI. The ideal feeding artery was that can supply entire pancreas according to arteriography and can maximize concentration of drug at pancreatic tissue. The pancreatic arteriography was considered as the final objective evidence for choice. Results （1）Gastroduodenal artery was chosen as feeding artery in forty-four cases, and superior mesenterlc artery was chosen in only one case because of vascular abnormity. （2）According to splenic arteriography, blood of splenic artery was supplied to spleen chiefly, and only partial tail of pancreas was applied by splenic artery. （3）According to celiac trunk arteriography, blood of celiac trunk could be supplied to entire pancreas, but a considerable proportion of the total blood was supplied to spleen through splenic artery and liver through hepatic artery proper.Therefore, the drug utilization index was lower. （4）According to gastroduodenal arteriography, blood of gastroduodenal artery could be supplied to entire pancrea, and almost all of the blood that contains drug flowed into pancreas. Therefore, the drug utilization index was higher. Conclusions Gastroduodenal artery is the ideal choice of artery which is used for regional intra-arterial infusion in sever acute pancreatitis. Pancreatic arteriography should be applied routinely when yever acute pancreatitis was treated with RAI.
