Ultrasounic Diagnosis of Budd-Chiari Syndrome with Hepatic Venous Outflow Obstruction / 中国医学影像学杂志

Purpose:The aim of this study was to investigate the diagnostic value of color Doppler Ultrasound in Budd-Chiari Syndrome (BCS) with hepatic venous(HV) outflow obstruction.Materials and Methods:The features of ultrasonography in 138 patients of Budd-Chian Syndrome were analyzed and compared with that of angiography.Results:83 patients had membranous obstruction and 45 segmental occlusion of HV.10 patients had HV stenosis.The ultrasound was able to reveal stenosis,atresia,emboli,or membranous obstruction in hepatic venous outflow tract.Collateral branches could be seen between the hepatic veins with short hepatic vein expanded.Both HV and IVC were involved in 35 cases,with thrombus in IVC in 11 and HV in 7.There was two false positive cases and 3 false negative in ultrasound diagnosis.Conclusion: The position and type of occlusion in HV could be accurately detected by color Doppler ultrasound,and so was the existence and degree of collateral circulation,which were of aid for the operation and follow-up.

s correlated with coronary disease. Examining these peripheral arteries, more efficient in combination, seems to be a helpful way for screening coronary disease.

Localization diagnosis of insulinoma by contrast-enhanced ultrasonography compared with laparoscopic ultrasonography / 中华超声影像学杂志

Objective To compare the value of contrast-enhanced ultrasonography (CEUS) with that of laparoscopic ultrasonography (LUS) in localization diagnosis of insulinoma. Methods Thirty-three patients with insulinoma,who received operation, were retrospectively reviewed. All cases were examined by both CEUS and LUS before the tumor removed. Both imaging modalities in diagnosis of insulinoma were analyzed. Results By this study the sensitivity and accuracy of CEUS were 92.31% and 90.0% respectively. Those of LUS were consistent with pathologic findings completely. The accuracy of CEUS was not different with that of LUS (χ2 = 4.21, P = 0. 04). Conclusions CEUS can be used for location diagnosis of insulinoma. For the patients expecting laparoscopic treatment, combination of CEUS with LUS will be suggested before insulinoma is removed.

Interventional treatment of hepatic or splenic trauma under the guidance of contrast-enhanced ultrasound:an animal experiment / 中华超声影像学杂志

Objective To determine whether hemostatic agents directly injected into injury sites under the guidance of contrast-enhanced ultrasound(CEUS)can effectively control hemorrhage from hepatic or splenic trauma. Methods Healthy adult dogs were impacted by a impactor to create hepatic or splenic trauma. Among 32 dogs,28 had hepatic or splenic injury of grade Ⅲ～Ⅳ according to Injury Scale of the American Association for the Surgery of Trauma(AAST),which were divided into two groups,the treatment group and the control. In the treatment group,hemocoagulase and α-cyanoacrylate were injected respectively into the injury site and transected micro-vessel tinder the guidance of CEUS,while in the control group,normal saline was injected. Results All animals of the two groups survived after the injection. CEUS demonstrated that active hemorrhage disappeared in treatment group but still existed in the control group.In the treatment group,laparotomy showed that hepatic or splenic injury had been covered and adhered with clot and glue membrane of hemostatic agents and free intraperitoneal blood volume was significantly less than that in the control group(P=0.000),while in the control group injury bleeding did not stop after injection. Conclusions Hemostatic agents injected under the guidance of CEUS can effectively control hemorrhage from hepatic or splenic trauma of grade Ⅲ～Ⅳ. This therapy was simple,convenient and effective. It may be performed immediately after hepatic or splenic injury was diagnosed.
