[Ultrasonic tomography of the mediastinum in the staging of lung cancer].

Results of standard X-ray tomography, computed tomography and ultrasonic tomography (UT) used for detecting mediastinal metastases from lung cancer were compared in 50 patients who were later operated on. UT sensitivity in the diagnosis of paravasal lymph node involvement proved superior to that of X-ray tomography and only slightly yielded to that of computed tomography. As regards bifurcation lymph node assessment, results of the radiation imaging techniques were similar to those obtained by surgery. Ultrasonographic signs of tumor spreading to the mediastinum were observed in cases of stage IIIa-IIIb tumors only. UT assured detection of metastases in normal-sized lymph nodes of the upper mediastinum. Combined application of standard X-ray and ultrasonic tomography of the mediastinum assured better staging of tumor roughly in half the patients. Absence of X-ray signs of mediastinal lymph node enlargement is considered a direct indication for UT.

[Embolization of the hepatic artery in the treatment of malignant tumors of the liver].

The results of therapeutic hepatic artery embolization (HAE) in 25 patients with malignant unresectable tumors of the liver are discussed. The proximal segments of the hepatic artery were occluded by metal spirals. Thrombosis of the portal vein was accepted as an absolute contraindication for HAE, and a tumor involving more than 50% of the volume of the liver and chronic hepatic insufficiency were considered relative contraindications. After the intervention signs of subjective improvement were noted in 73.9% and signs of objective improvement in 65.2% of cases. The mortality after HAE was 4.2%. The obtained results are evidence of the efficacy of proximal HAE as a method for the treatment of inoperable malignant tumors of the liver.

[Potentialities of ultrasound and computed tomography in the diagnosis of metastases of lung cancer in the mediastinal lymph nodes].

The results of routine roentgenotomography, CT and USI in the diagnosis of intrathoracic metastases of lung cancer were compared in 69 patients (central type--52, peripheral--17). These results were compared with operative findings in 45 patients. The sensitivity of USI in the diagnosis of enlarged paravasal lymph nodes exceeded that of roentgenotomography and was slightly inferior to CT. CT was informative for all mediastinal lymph nodes whereas tomography and USI were informative in certain areas only. The authors recommend to combine the use of routine and ultrasound tomography to assess the spreading of lung cancer to the mediastinum. The information obtained increases the accuracy of staging and specifying a process, slightly yielding CT results.
