A new technique of bedside pulmonary arteriography is described, in which small volumes of contrast material are injected manually in order to obtain segmental arteriograms in patients who are too ill to undergo conventional pulmonary angiography. This method is safe and effective and can provide information which is useful in the management of certain critically ill patients.
Loop et al. (1975) studied this question.
