Clinical value of color Doppler ultrasound and computed tomography angiography in diagnosis and interventional therapy of Budd-Chiari syndrome / 局解手术学杂志

Objective To evaluate the clinical value of color Doppler ultrasound (CDUS) and computed tomography angiography (CTA) in diagnosis of Budd-Chiari syndrome(BCS).Methods The CDUS and CTA data about 33 BCS patients diagnosed by digital subtraction angiography(DSA) and treated by interventional therapy were retrospectively analyzed.All of 33 patients with BCS were examined with CDUS,26 cases of then received CTA.The diagnostic value of BCS between two methods were compared.Results The diagnostic accordance rate of CDUS and CTA for BCS were 90.9％ and 96.2％ respectively,which had no significant statistical difference(P ＞ 0.05).The two methods could not only comprehensively systematically reflect the morphologic changes of liver and spleen,the stenosis and blood flow state of the lesion regions,but also clearly display the intrahepatic/extrahepatic collateral vessels trend in the abdomen.One week after interventional therapy,the CUDS results showed blood vessels pristine and stable hemodynamics.Conclusion CDUS is the preferred imaging in the diagnosis and postoperative re-examination of BCS.While,CTA can provide many important parameters for preoperative assessment and operation way.

Ultrasonographic diagnosis of benign,borderline and malignant ovarian epithelial tumors / 中华超声影像学杂志

Objective To study the value of ultrasonographic diagnosis of benign,borderline and malignant ovarian epithelial tumors.Methods In the 203 patients of ovarian epithelial tumors,the substantial tissues′ area of 128 cases with cyst-solid mass was measured through ultrasonography and compared with pathology.Results The area of substantial tissues in ovarian epithelial tumors was benign 5 cm 2 were regarded as optimal threshold values for differentiation of the benign,the borderline and the malignancy,their sensitivities were 94.7% , 80.0% and 90.7% ,their specificities were 96.3% , 92.4% and 97.6% ,accuracies were 96.1% , 90.0% and 92.9% .Conclusions It provides an effective method for diagnosis of benign, borderline and malignant ovarian epithelial tumors.If combined with conditions of color Doppler flow imaging, and comprehensive consideration on greater omentum and lymph node, the accurate diagnostic rate will be increased.
