[Value of CT imaging of inferior vena cava and hepatic vein in patients with hepatic cystic echinococcosis].

To evaluate the accuracy of CT imaging of inferior vena cava and hepatic vein in patients with hepatic cystic echinococcosis. A total of 100 patients with hepatic cystic echinococcosis were given triple-phase abdominal CT scan, and the reconstructed images of the inferior vena cava and hepatic vein were obtained and compared to the real situation during the surgical operation. The reliability of the CT evaluation of the echinococcus cyst lesion invading inferior vena cava and hepatic vein was analyzed. The compression displacement, half-globular, no clear demarcation between the lesion and blood vessel and narrowing of the vessel detected by CT evaluation were in accordance with the real situation under the surgical sight. However, four cases of clear demarcation between the lesion and blood vessel were affirmed wrong under the surgical sight. There were three cases of over diagnosis of vascular stenosis judgments. The CT images of hepatic vein and inferior vena cava can clearly show the relationship between the hepatic echinococcus cyst and hepatic vein and inferior vena cava. [
