Combined ethanol and radiofrequency ablation for the elimination of focal atrial tachycardia originating from the Marshall bundle.

Introduction And Importance: Atrial tachycardias (AT) originating from the Marshall bundle (MB) are rare and present significant challenges in diagnosis and management. The authors present the case of a 29-year-old male with recurrent AT successfully treated with a combined ethanol and radiofrequency ablation approach. This case highlights the effectiveness of this dual ablation strategy in resolving AT originating from the MB, contributing valuable insights into managing complex AT cases.

Features of endothelium morphological structure in kidney vessels, coronary arteries and aorta during chronic kidney disease.

Objective: Introduction: Vascular endothelium function interruption has the main role among mechanisms of development and progression of chronic kidney disease. In numerous experimental and clinical studies, it was proved that activated vascular endothelium is a structural and functional unit that matches processes of inflammation with intravascular coagulation, fibrinolysis and haemorheological disorders. The aim: To identify special features of endothelium morphological structure in kidney vessels, coronary arteries and aorta during chronic kidney disease.

Role of ischemic preconditioning in hepatic ischemia-reperfusion injury.

Background: Investigation into less traumatic method of vascular occlusion during liver resection is the actual problem in hepatic surgery because of high level of complications such as liver failure. In this connection, the goal of our study was to determine the optimal model of vascular clamping. The research showed that vascular occlusion with ischemic preconditioning in the mode 5/10/15 the most delicate technique.
