Right Heart Echocardiography Parameters and Other Predictors to Evaluate Mechanical Cardiac Support Necessity During Lung Transplantation.

BACKGROUND: Lung transplantation (LuTx) is a challenge when right heart function fails. Mechanical circulatory support (MCS) is then necessary. METHODS: We aimed to investigate whether preoperative transthoracic echocardiography (TTE) can predict MCS use and help to exclude the sickest patients. Between 2011 and 2018, 52 patients at our institution received LuTx and qualified for this study: 35 bilateral, 16 single, 1 lobar [1] and 1 retransplantation procedure. Of these, 22 were operated using MCS and 30 without MCS. The patients were aged between 18 and 65 years, and 23 were women. The indications were lung fibrosis for 18 patients, chronic obstructive lung disease for 16, cystic fibrosis for 15, primary pulmonary hypertension for 2 and bronchiectasis for 1. TTE was performed up to 30 days before treatment and 1 to 7 days after. RESULTS: Patients undergoing MCS versus patients not undergoing MCS: preoperative right ventricular systolic pressure 56.5 (30) vs 37.8 (11.5) mm Hg (P = .03); tricuspid regurgitation pressure gradient 48.7 (27) vs 30.2 (10.8) mm Hg (P = .015); tricuspid annular plane systolic excursion 17.8 (4.3) vs 19.9 (2.8) mm Hg (P = .04); pulmonary artery diameter 27.5 (5.2) vs 23.9 (4.1) mm (P = .004); age 41.9 (14.1) vs 54.3 (11.8) years (P = .001). Patients who were Dead versus patients who were alive pulmonary valve acceleration time of 82.8 (24.1) vs 104.9 (27.2) ms (hazard ratio [HR] = 0.959, 95% confidence interval [CI] = 0.923-0.996 per ms, P = .02) and pulmonary artery diameter of 28.9 (5.8) vs 24.4 (4.1) mm HR = 1.225, 95% CI = 1.028-1.460 per 1 mm, P = .016 were predictors of death. CONCLUSIONS: Preoperative TTE parameters: right ventricular systolic pressure, tricuspid regurgitation pressure gradient, tricuspid annular plane systolic excursion, and pulmonary artery diameter predicted MCS use during LuTx. Certain values of valve acceleration time and pulmonary artery diameter could help discern LuTx qualification.

Pneumopericardium as a non-small-cell lung carcinoma complication.

Below we present a case of a young man with symptoms of progressive weakness, fever, cough, rapid decrease in body weight and the presence of a tumor in the left axillary region. The chest radiography and echocardiography revealed gas bubbles in the pericardium. The more detailed diagnostics and computed tomography of the chest showed an infiltration of the left lung cavity and a fistula among the bronchus, pleural and pericardial cavities. Further diagnostics demonstrated that the pneumopericardium (diagnosed by means of chest radiograph and echocardiography) was a complication of a primary non-small-cell lung carcinoma.

Veno-venous extracorporeal membrane oxygenation in a patient with severe acute respiratory failure - case report.

Acute respiratory failure resistant to conventional pulmonary therapy often requires intensive medical care. In rare cases, ventilator therapy proves insufficient, and only the option of employing veno-venous extracorporeal membrane oxygenation (ECMO V-V) remains. The present article describes the case of a 23-year-old patient who experienced severe acute respiratory distress syndrome with associated multiple organ failure. The patient was admitted to the pulmonary ward of the Alfred Sokolowski Regional Pulmonary Hospital in Szczecin-Zdunowo with suspected pneumonia of unknown etiology. After the initial 5 days of diagnostics at the pulmonary ward, the patient required a further 97 days of hospital treatment and spent 63 days at the Intensive Care Unit. There, he underwent ECMO V-V therapy lasting 22 days, which resulted in the improvement of his arterial blood gas parameters and clinical condition.

Surgeon's viewpoint on lung transplantation in cystic fibrosis patients - preliminary report.

INTRODUCTION: The surgeon's viewpoint on a patient with cystic fibrosis differs from that of a pediatrician or internist. The problems a cystic fibrosis specialist encounters are different from those faced by the surgeon who takes over the patient in a very advanced, often terminal stage of the disease. Hence, the main problem for the surgeon is the decision concerning the surgery (lung transplantation, pneumonectomy, lobectomy). It is, therefore, important to lay down fundamental and appropriate rules concerning the indications and contraindications for lung transplantation, especially in patients with cystic fibrosis. AIM: The aim of this study was to analyze the methods of qualifying and preparing patients for surgery, as well as carrying out the procedure of transplantation and postoperative short and long-term care. MATERIAL AND METHODS: The investigation was carried out on 16 patients with cystic fibrosis. Three were operated on and 10 were on the waiting list for transplantation. Two patients on the waiting list died, one patient was disqualified from transplantation. During qualification for lung transplantation, strict indications, contraindications and other factors (such as blood type, patient's height, coexisting complications) were taken under consideration. RESULTS: All the 3 patients after lung transplantation are alive and under our constant surveillance. Ten patients await transplantation, though four of them are suspended due to hepatitis C infection. Two patients on the waiting list died: one from respiratory insufficiency and the other in the course of bridge to-transplant veno-venous extracorporeal membrane oxygenation due to hepatic failure. One patient has been disqualified because of cachexia. CONCLUSIONS: Since lung transplantation is the final treatment of the end-stage pulmonary insufficiency in cystic fibrosis patients, the number of such procedures in cystic fibrosis is still too low in Poland. The fast development of these procedures is highly needed. It is necessary to develop better cooperation between different disciplines and specialists, especially between pediatricians and surgeons. The correct choice of the suitable moment for lung transplantation is crucial for the success of the procedure.

[Primary pulmonary mucosa-associated lymphoid tissue lymphoma: a case report]. / Chloniak typu MALT o lokalizacji plucnej - opis przypadku.

Primary pulmonary lymphoma accounts only 0,5% of all primary lung neoplasms. Mucosa-associated lymphoid tissue (MALT) lymphoma is a low grade B-cell extranodal lymphoma. It is a quite infrequent entity, however it constitutes from 72% to 90% of all pulmonary lung lymphomas. Long-term stimulation of bronchus-associated lymphoid tissue by antigens, smoking, inflammatory disorders or autoimmune diseases are thought to be leading to the development of MALT lymphoma. We present the case of primary pulmonary mucosa-associated lymphoid tissue lymphoma. A 76-year-old man with a history of heavy smoking (22.5 pack years) was admitted to the hospital for a further diagnostics of an abnormal finding in the right lung visualized on the chest X-ray. The diagnostic process, including imagining studies did not reveal the etiology of a lesion in the right lung. The patient was qualified for surgical diagnostics. The histological finding confirmed extranodal marginal low-grade B-cell lymphoma of mucosa -associated lymphoid tissue.

Single lung transplantation in a patient with retrospective positive cross-match.

Lung transplantation is a method useful in such non-malignant end-stage parenchymal and vascular diseases as: chronic obstructive pulmonary disease (COPD), idiopathic interstitial pulmonary fibrosis, cystic fibrosis, or primary pulmonary hypertension. The main aim of this procedure is to extend the patient's lifespan and quality of life. However, the availability of the operation is limited by organ access. In this paper we present the case of a 58-year-old female in the fourth stage of COPD, who was classified to have a single lung transplantation. Because of some technical problems it was decided to transplant a left donor lung in the right recipient lung locus. Positive cross match was demonstrated retrospectively, and we applied five courses of plasmapheresis. Human immunoglobulin and rituximab treatment were performed to decrease the impact of lymphocytotoxic antibodies. The patient survived 498 days after transplantation, 271 in the hospital.
