不同类型急性胰腺炎CT图像肠系膜上动脉与肠系膜上静脉比值的对比分析

SMA/SMV RATIO ANALYSIS ON CT FILM AMONG VARIOUS PACREATITIS

目的：探讨肠系膜上动脉（ＳＭＡ）与肠系膜上静脉（ＳＭＶ）的比值大小与急性胰腺炎病情轻重程度的关系。方法：对６０例急性胰腺炎病人与６０例正常人的ＣＴ扫描片测量ＳＭＡ与ＳＭＶ的比值并进行对比分析。结果：急性胰腺炎的ＳＭＡ与ＳＭＶ的比值低于正常人，其中重症急性胰腺炎的比值小于轻症。结论：急性胰腺炎的ＳＭＡ／ＳＭＶ比值与其临床类型密切相关，有可能作为一项新的指标来判断严重程度及估计预后。

OBJECTIVE: To determine association between SMA/SMV ratio and severity of pacreatitis. METHOD: SMA/SMV ratio on CT film was measured among 60 patients with pancreatitis and 60 healthy people. RESULTS: The SMA/SMV ratio in acute pancreatitis was lower than healthy individual, so is the mild patient than severe patient. CONCLUSION: SMA/SMV ratio is closely associated with severity of pancreatitis and can be an index to evaluate severity and prognosis.
