[Endovascular interventions in true and false aneurysms of hepatic, splenic and renal arteries]

A false aneurysm of visceral arteries is a life-threatening pathology sufficiently difficult to treat. Open operations are characterised by a large scope, considerable surgical injury and accompanied by a high rate of serious complications. The development of the technology of superselective catheterization of blood vessels, creation of specialized microcatheters, glue composites and various types of spirals made it possible to treat this severe pathology without resorting to open operations. The work deals with a brief literature review concerning epidemiology, methods of diagnosis and treatment of pseudoaneurysms of visceral arteries, followed by presenting three clinical case reports concerning successful treatment of posttraumatic false aneurysms of the right hepatic and splenic arteries, as well as an aneurysm of the renal artery. Both immediate and remote results of endovascular interventions in these patients are followed up, demonstrably showing possibilities of endovascular technologies in treatment of the pathology involved.

[Electrocardiographic changes during coronarography]

The endocardial manipulations and bolus intracoronary administration of contrast substances, of the first generation in particular, can induce disturbances of the myocardium repolarization and different disturbances of the cardiac rhythm, life-threatening included. The aim of the investigation is to assess transitory electrophysiological alterations in the myocardium during coronarography and during the first day after it. Under examination there were 39 patients with ischemic heart disease and stenocardia of the II-III functional classes in whom the coronarography was performed according to clinical indications. The Holtner dynamic observation of ECG was made in all the patients. All the ECG changes were detected and estimated during coronarography: arrhythmias, disturbances of conduction and transitory ischemic alterations of the myocardium. It gives a possibility to decide between the methods of pharmacological correction of possible disturbances.
