Perfusion Lung

Perfusion lung scintigraphy is probably the most reliable noninvasive tool to evaluate restoration of pulmonary blood flow after pulmonary embolism. In spite of that, its use is often limited to the acute phase of pulmonary embolism. Since abnormalities of the arterial blood gases and expired air composition are the most important functional consequences fol­lowing acute pulmonary embolism, evaluation of pulmonary gas exchange could give information about the functional recovery during treatment. Unfortu­nately, neither the rate of gas exchange recovery, which could be used as an index of blood flow restoration, nor the relationship between gas exchange and the extent of pulmonary embolism is sufficiently known up to date. Moreover, little is known about chest roentgenographic abnormalities during the follow-up of treated pulmonary embolism.

The purpose of this study is to assess whether the combination of simple techniques, such as pulmonary gas exchange data and the chest roentgenogram, may allow a better evaluation of the anatomic and functional recovery of patients with pulmonary embolism under the effect of therapy. To this end, we compared pulmonary gas exchange parameters and chest x-ray findings with perfusion lung scintigraphic abnormali­ties, both during the acute stage of pulmonary embo­lism and over a period of six months following the diagnosis in man. Viagra Professional
