[Circular Sympathetic Pulmonary Artery Denervation in Cardiac Surgery Patients With Mitral Valve Defect, Atrial Fibrillation and High Pulmonary Hypertension].

Objective Investigate the influence of the sympathetic denervation of the pulmonary trunk and the orifices of the pulmonary arteries on the degree of pulmonary hypertension (PH) and outcomes of the surgical treatment of atrial fibrillation (AF) in patients with mitral valve defects, complicated AF, and high PH.Material and methods We analyzed the surgical treatment of 140 patients with mitral valve defect, concomitant AF, and high PH - pulmonary artery systolic pressure (PASP) gradient more than 40 mm Hg. The group of interest included 51 patients (46 patients with severe mitral stenosis and five patients with grade 4 mitral valve regurgitation).

[Effect of intraoperative infusion-transfusion therapy on mortality of patients with massive blood loss].

The aim of the research is to determine the influence of infusion-transfusion therapy of the volume and structure on intraoperation and hospital lethality in patients with injuries and diseases, complicated in blood loss, exceeding circulating blood volume (CBV). It was conducted a retrospective analysis of the anaesthesia flow, infusion-transfusion therapy and treatment results in 112 patients with injuries and diseases complicated in intra-abdominal bleeding, volume of more than 4 liters. It was found that the risk of death increases in low-volume infusion therapy (less than 1.

[The intraoperative auto- and allohemotransfusion by massive bleeding in emergency abdominal surgery].

The results of intraoperative hemotransfusion of 112 patients with abdominal injuries, complicated with bleeding and the loss of more then 70% of the circulating blood. The aim of the study was to compare the efficacy of auto- and allohemotransfusion. The first method allowed to decrease both the overall lethality (p=0.

[Automatic blood reinfusion in intraabdominal bleedings].

147 patients with polytrauma, complicated by acute large-volume intraabdominal bleeding, were included in the study. Anesthetic regimens and blood loss compensation were retrospectively analyzed. Thus, all patints were divided inti 3 groups: 1st group received only intraoperative blood reinfusion, 2nd group - got auto- and donor blood reinfusion, 3rd group had only donor blood transfusions.
