[Complications of transcutaneous transhepatic endovascular interventions in patients with portal hypertension].

Results of endovasal treatment of 196 patients with portal hypertension and its complications are analysed. The total rate of complications is 23.4%, the most serious of them were intraabdominal bleeding (2.

[Radiographic endovascular correction of hyperaldosteronism in patients with arterial hypertension].

The authors describe a new method of X-ray endovascular destruction of the adrenal in patients with arterial hypertension and hyperaldosteronism. Destruction of the adrenal is accomplished by acute occlusion of its venous channel by introduction of a 3% thrombovar solution through a catheter installed in the central vein of the suprarenal gland. This method was applied in 22 patients with arterial hypertension; essential hypertension with secondary hyperaldosteronism was found in 18 of them, renoparenchymatous hypertension in 2, aldosteroma of the left adrenal in one, and Itsenko-Cushing's disease in one patient.

[Endovascular diagnosis and transcatheter procedures in portal hypertension].

The results of endovascular diagnosis and transcatheter surgery in 113 patients with various forms and stages of portal hypertension are analysed. A total of 761 diagnostic and 194 therapeutic radiologically-guided endovascular interventions were carried out. Purposeful study of the arteriovenous angioarchitectonics in the hepato-lienal system, the character and degree of disorders of the portal-hepatic hemodynamics, and the peculiar features of collateral circulation before and after various radiologically-guided interventions allowed the authors to elaborate an orderly system of stage-by-stage endovascular treatment of patients suffering from portal hypertension.

[Transhepatic transportal embolization of gastroesophageal veins in profuse esophageal hemorrhage].

The article deals with the results of treatment of 27 patients with profuse esophageal hemorrhage in portal hypertension. Sixteen patients were treated by roentgen-guided endovascular surgery, namely, transhepatic transportal embolization of varicose veins of the esophagus and stomach. In view of the peculiarities of blood drainage and for the prevention of recurrent bleeding, seven patients were subjected to additional manipulations: embolization of the splenic artery (4) and the left gastric artery (3).
