摘　　要：本文通过用双螺旋ＣＴ扫描，测量ＳＭＡ（ＳｕｐｅｒｉｏｒＭｅｓｅｎｔｅｒｉｃＡｒｔｅｒｙ）和ＳＭＶ（Ｓｕｐｅ－ｒｉｏｒＭｅｓｅｎｔｅｒｉｃＶｅｉｎ）的直径，ＳＭＡ直径测量恰好在ＳＭＡ的起始部，ＳＭＶ直径测量恰好在ＳＭＶ与门静脉汇合前。计算２０例急性胰腺炎治疗前后ＳＭＡ／ＡＭＶ的值。治疗后ＳＭＡ／ＳＭＶ的值均比治疗前的增大。结论是：有效治疗后ＳＭＡ／ＳＭＶ的值是评价急性胰腺炎疗效一个有效的新指标。This study measured the diameters of SMA (superior mesenteric artery) and SMV (superior mesenteric vein) on spiral CT scans.The diameter of SMA was measured just the origin of SMA,the diameter of SMV was measured just caudal to the portal confluens.In 20 acute pancreatitis patients,the ratios of SMA and SMV diameter in pre treatment and post treatment was obtained resepectively.In conclusion,artery to vein ratio using the superior mesenteric vessels is a new criterion in treatment of acute pancreatitis with spiral CT.
