- Central venous catheters provide an important means of vascular access and are increasingly used. Catheter occlusion refers to the inability to infuse or withdraw fluids from a catheter and could be caused by either thrombotic or nonthrombotic origin. We report an unusual malfunction of double lumen central venous catheter due to kinking and bending of the catheter at the opening site of proximal lumen.

- 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.
