ABSTRACT
UNLABELLED: The aim of the study---a comprehensive assessment of haemodynamic alterations during pneumonectomy using pulmonary arterial volumeter (PAV) opportunities. MATERIALS AND METHODS: 72 patients were included in the study, (the average age - 51 +/- 3,8 years, body weight - 68 +/- 7 kg), who underwent pneumonectomy about lung tumors under general anesthesia with separate ventilation (on indications - jet high-frequency ventilaton).

The article gives detailed description of a technique of pulmonary endarterectomy in chronic thromboembolic pulmonary hypertension. The method is based on the experience of the world leader in surgical treatment of this disease--the clinic of California, San Diego headed by Stuart Jamieson, cardiothoracal clinic Papworth Hospital in the only center in Great Britain, where PE is performed and on the experience obtained by the collective of the Department of hospital surgery of the medical department of the St. Petersburg state University and the City multi-field hospital.

Lung transplantation is one of the most difficult fields of contemporary transplantology. The operation was performed on a 53-year-old female who had been suffering from terminal stage COPD. The period of cold ischemia for the right and left lung was 1 hour 30 minutes and 2 hours 25 minutes respectively. The total operation time was 4 hours and 40 minutes. There were no surgical complications. There were no signs of transplant rejection 6 weeks after the operation. The considerable decrease in dispnea and increase in quality of life were registered during the follow-up. FEV1 was increased by 80% and 6 minute walk test distance was increased by 200 meters.

Latent dysfunction of the heart right ventricle and hypovolemia were assessed in 50 patients divided into 4 groups, operated on the heart, abdominal aorta and lungs. It was found that after revascularization of the myocardium the diastolic disorders prevailed. In patients operated for the heart valve (mitral and aortal) diseases prevailing were the systolic and pump dysfunction of the right ventricle. Insufficiency of the right ventricle in these groups was 13% and 22% respectively. After operations on the abdominal aorta a combination of the systolic and diastolic impairments of the right ventricle were observed. After extended resections of the lungs there was a characteristic combination of systolic, diastolic and pump dysfunctions. When the operation was followed by a decreased minute volume of circulation, its cause was hypovolemia in 29% of cases in the examined surgical patients. The investigation of the right ventricle functions with the help of pulmonary arterial volumetry can reveal their latent dysfunctions as well as hypovolemia in a considerable part of surgical patients.

Twenty-two tests on perfusion of xenospleen and its sections with different transfusion media as well as clinical experience on 50 cases of extracorporeal perfusion of xenospleen and its sections with autoplasma of surgical and cardiosurgical patients have shown that it was possible to minimize depositing and loss of formed blood elements and microcirculation disturbances as well as to prolong the time of xenoorgan active functioning. Positive result has been obtained in all the cases when xenospleen splenoplasmosorption was used in surgical and cardiosurgical patients with pyoseptic complications.

The analysis of 65 cases of cardiopulmonary bypass surgery using systems distinct in the type of the oxygenator used (contact, membrane) and the degree of thromboresistance of blood-contacting surfaces has demonstrated that the use of heparin-covered membrane blood oxygenators and systems allows of a considerable reduction in blood trauma during perfusion and a 5-6-fold decrease of heparin doses employed for extracorporeal membrane blood oxygenation.
