“…The latter are helpful in separating patients with pulmonary embolism alone from those with embolism and chronic lung disease. Pulmonary function studies also provide a simple means of following the disease process (Bass, Banas & Dalen, 1970).…”

SummaryThe advantages of lung scanning in suspected pulmonary embolism are its diagnostic sensitivity, simplicity and safety. The ability to delineate regional pulmonary ischaemia, to quantitate its extent and to follow its response to therapy provides valuable clinical data available by no other simple means. The negative scan effectively excludes pulmonary embolism but, although certain ofits features favour the diagnosis of embolism, the positive scan inherently lacks specificity and requires angiographic confirmation when embolectomy, caval plication or infusion of a thrombolytic agent are contemplated. The addition of simple ventilation imging techniques with radioxenon overcomes this limitation by providing accurate analog estimation or digital quantitation of regional ventilation: perfusion (V/Q) ratios fundamental to understanding the pathophysiologic consequences of embolism and other diseases of the lung.

Massive pulmonary embolism without arterial hypoxaemia

et al. 1977

Two cases of massive pulmonary embolism, confirmed by angiographic or necropsy findings, were remarkable by the absence of arterial hypoxaemia. The various mechanisms responsible for arterial hypoxaemia in pulmonary embolism are discussed. It is suggested that in patients with massive pulmonary embolism a markedly decreased cardiac output might account for the absence of arterial hypoxaemia. In the light of these two cases the finding of a normal PaO2 does not rule out the diagnosis of pulmonary embolism.
