Conclusion
- Pulmonary embolism is one of the causes of an exacerbation of COPD and its frequency have we examined patients was 17.8%.
- MSCT is highly effective method of early diagnostics of pulmonary embolism in patients with COPD.
The peculiarity of PE in this category of patients is predominantly combined bilateral defeat of various segments of the pulmonary artery and the highest percentage of lung infarctions.
- CT-venography of the low extremity is effective method of identifying the causes of venous thrombosis.
This method may by used as independent procedure rapid and complex MSCT diagnostic of pulmonary embolism in patients with COPD.
- The most significant clinical signs of PE in patients with COPD are expressed unmotivated shortness of breath (3-4 degree on a scale MRCDS) and pain in the chest due lung infarctions.
- Perfusion scintigraphy in patients with COPD often,
than in other diseases diagnostic unreliable (>30%),
which is caused by the violation of pulmonary perfusion as a result of a reactive vasoconstriction due to bronchial obstruction.
