[Ultrasonographic symptoms of portal hypertension].

Ultrasound investigation was performed in 49 patients with the syndrome of portal hypertension. A portal blood flow blockade level could be determined by the type of changes of the abdominal and hepatic vessels. Portal hypertension of intrahepatic type was characterized by the dilated portal and splenic veins and the hepatic artery.

[Puncture biopsy with ultrasonic control in the diagnosis of space-occupying lesions of the organs of the abdominal cavity and lesser pelvis].

Fine-needle puncture aspiration biopsy was performed in 182 patients with various visceral tumors. The results were negative in 4 (2.2%) cases only.

[Ultrasonic diagnosis of voluminous formations in the abdominal cavity and retroperitoneal space in newborn infants].

Introduction of the ultrasound research method into obstetrical practice has given rise to a possibility of revealing developmental abnormalities and neoformations in the prenatal period. The same method enables identifying volumetric formations in the abdominal cavity and retroperitoneal space in the newborn. Ultrasound examination of the newborn presupposes the obligatory use of the equipment working in the real time mode, with a high rate of image design as well as the use of monitors run at a frequency of not less than 5 to 7.

[Lymphography, computed tomography and ultrasonic examination in determining the involvement of retroperitoneal and abdominal lymph nodes in Hodgkin's disease].

Altogether 45 patients with Hodgkin's disease were examined with the help of lymphography (LG), computerized tomography (CT) and ultrasonography (USG). The LG, CT and USG results obtained in 20 patients were compared with the histological findings. The retroperitoneal lymph nodes contrasted in LG, when involved in a pathological process, were detected with approximately the same accuracy in CT and USG.

[Ultrasound diagnosis of the involvement of retroperitoneal and abdominal lymph nodes in Hodgkin's disease].

Ultrasonography and lymphography have been carried out in 238 patients with Hodgkin's disease to define the stage, recurrences and evaluate the efficiency of treatment. In 35 cases the results have been verified by morphologic study of lymph nodes removed during laparotomies. The results of ultrasonic study demonstrate involvement of lymph nodes of the spleen hilum, liver and other abdominal nodes found in 14 out of 115 untreated patients.

[Ultrasonic diagnosis of splenic and hepatic lesions in lymphogranulomatosis].

Ultrasound investigation was conducted in 21 patients with Hodgkin's disease to determine the involvement of the spleen and liver in the process. The results obtained were verified histologically in 19 cases at laporotomy and in 2 cases at autopsy. Focal spleen lesion (focal sizes from 0.

[Pharmacolymphography (author's transl)].

In 110 patients with different malignant tumors various pharmacological substances (Ridol (G. Richter, Hungary), Arphonad (Hoffmann, Switzerland), Xavin (Chinoin, Hungary) etc.) were used in lymphography to improve inflow of contrast medium and visualization of lymph vessels and nodes.

[Pharmacolymphography].

With the goal of accelerating the contrast-medium injection at the lymphography and improving the contrasting of the vessels and node conduction system the authors applied a variety of pharmacological preparations: Ridol (G. Richter), Nospanum (Quinoine, HPR), Arfonadum (Hoffman-La Rochet, Switzerland), Xavinum (Quinoine) etc. in 110 cases of various malignant neoplasms.
