Abstract:
BACKGROUND: Pulmonary artery ligation during pneumonectomy increase the pulmonary blood flow of dependent lung and may increase the pulmonary arterial pressure and pulmonary vascular resistance. The purpose of this study is to evaluate the hemodynamic effect of pulmonary artery ligation during pneumonectomy. METHODS: Nine patients who were supposed to receive pneumonectomy were studied. Hemodynamic measurements were performed following two lung ventilation (TLV), one lung ventilation (OLV), after pulmonary artery ligation and after pneumonectomy. RESULTS: There is no significant differences in heart rate, systemic arterial pressure, pulmonary arterial pressure, pulmonary capillary wedge pressure, cardiac index and pulmonary vascular resistance index. Arterial oxygen tension significantly reduced during OLV and increased after pulmonary artery ligation and after pneumonectomy. CONCLUSIONS: These results suggest that pulmonary artery ligation during pneumonectomy may not affect the cardiopulmonary hemodynamics.
