[Roentgenological-endovascular occlusion and ligation of internal iliac arteries in bleeding tumors of the bladder].

A comparative estimation of the effectiveness of hemostasis by means of ligation of the internal iliac arteries and roentgen-endovascular occlusion of these vessels was carried out in 30 patients with a bleeding carcinoma of the urinary bladder and prostate growing into its wall. For the occlusion of the internal iliac artery metallic spirals were used in 15 patients, in 4 of them they were used in combination with a gelatine sponge. The roentgen-endovascular occlusion is thought by the authors to be the method of choice.

[Hepatic artery changes in liver cirrhosis].

The results of selective celiacography in 50 patients with the intrahepatic form of portal hypertension have shown that in addition to constriction and deformation of terminal portions of the lobular, segmentary and subsegmentary arteries due to cirrhotic alterations of the liver there is some dilatation of extraorganic parts of the hepatic artery which is more pronounced in well formed cirrhosis of the liver with moderate portal hypertension.

[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. All the selected drugs are, to a greater or lesser extent, of a vasodilative effect. It has been found that Ridol together with the combination of Novocaine and Nospanum produce a pronounced lymphotropic effect. Pharmacolymphography with these preparations contributes to the shortening of the time necessary for the injection of contrast-medium and also improves the image of the intermediate node sinuses and of the thoracic duct.

[Intravascular repair in extended arterial occlusive lesions (a preliminary communication)].

Subintimal recanalization as a procedure of percutaneous vascular repair is under study now. The Regional Clinical Hospital has performed 10 procedures of subintimal angioplasty in patients with extended total occlusions of iliac and femoral arteries. All the patients had presented with critical ischemia of the lower extremities with the mean humeromalleolar index of 0.24+/-0.08. A technical success was achieved in 8 patients in whom the mean humeromalleolar index was 0.37+/-0.09. There were no procedure-associated complications.

[Metallic endoprostheses in the treatment of benign strictures of the biliary tract].

Nine original nitinol self-smoothing-out stents and 3 Gianturco stents were implanted to treat benign strictures of biliary ducts and biliodigestive anastomosis after ineffective repeated attempts to make balloon dilatation. There were no complications associated with the implantation procedure. The follow-up of patients varied from 3 to 26 months. After 4 months, reobturation was revealed at the site of repair in one case, which required implantation of an additional stent coated with polytetrafluoroethylene. The patency of the biliary tract was preserved in the remaining patients in the above period.

Transcatheter treatment of splenic artery aneurysms (SAA). Report of two cases.

Splenic artery embolization with steel coils was performed in two patients who both had large splenic artery aneurysms and hepatic cirrhosis complicated by hypersplenism. A good clinical effect was noticed after the procedure. It was concluded that this treatment is safe and effective and decreases the risk of splenic artery rupture. It also corrects hypersplenism. Transcatheter embolization appears to be a preferable alternative to surgery in such cases.
