live long enough for a planned surgical procedure to be instituted. Up to 1961 only 21 successful pulmonary embolectomies had been reported in the world literature, but since the introduction of cardiopulmonary bypass by Sharp (1962) a large number of successful embolectomies have been reported from many centres (Beale and Cooley, 1965; Cross and Mowlem, 1967; Barraclough and Baimbridge, 1967). A new view of the natural history of the disease (Sautter et al., 1967) and the introduction of enzyme therapy (Sasahara et al., 1967) have diverted attention away from surgical treatment. Nevertheless, follow-up studies of patients treated for pulmonary embolism with streptokinase and heparin have shown that large areas of lung may remain underperfused one year later (Gunning, 1971). If these studies are substantiated the pendulum may once again swing in favour of surgical treatment, and when cardiopulmonary bypass is not available the possibility of bringing a flying squad from the nearest cardiothoracic surgical centre to the patient should be explored.
