摘 要:目的 应用彩色多普勒血流显像 (CDFI)技术 ,探讨该技术在诊断急性胆囊炎中的意义。方法 检测 2 78例胆囊 ,其中急性胆囊炎 1 0 8例 ,慢性胆囊炎伴胆囊结石 71例 ,正常对照组 99例。观察胆囊壁内胆囊动脉血供 ,测定收缩期最大血流速度 (Vmax)、舒张期最小血流速度 (Vmin) ,及阻力指数 (RI)。各组间相互比较。结果 急性胆囊炎组 Vmax(4 1 .3± 1 5 .3) m/ s、Vmin明显高于其他二组 (P<0 .0 5 ) ,RI无显著性差异。如以胆囊动脉血流流速 0 .36 m/ s确定为临界值 ,其敏感度为 72 .7% ,特异度为 93.4 % ,正确度为 88.8%。Objective To estimate the value of CDFI technique in diagnosis of acute cholecystitis.Methods Two hundred and seventy eight gallbladders were examined.One hundred and eight cases(108/278) were with acute cholecystitis,(ch group),chronic cholecystitis with cholecystolithiasis,(77 cases,cl group)and normal,(99 cases,in n group):We measured the maximum flow velocity (Vmax),the minimum flow velocity (Vmin) and the resistant index (RI) of cystic arterial blood flow in the gallbladder . Results The Vmax(41 3±15 3m/s) in the ch group were evidently higher than those of the other two groups,There were apparent differences ( P <0 05). RI,had no difference between these three groups.If the cystic arterial flow velocity of 0 36m/s was the diagnostic cut off value,the sensitivity ,specificity,and accuracy rate were 72 7%,93 4% and 88 8% respectively.Conclusions The measurement of arterial flow with CDFI has an important value in the diagnosis of acute cholecystitis.
