The value of bedside wedge pulmonary angiography in the detection of pulmonary emboli: a predictive and prospective evaluation.

A predictive study involving 74 unequivocally positive conventional pulmonary angiograms was conducted to determine the value of bedside, flow-directed wedge pulmonary angiography (BWPA). The flow-directed position of Swan-Ganz catheters in these cases was obtained from anteroposterior chest radiographs. BWPA could detect the embolism in 48% of the cases in… CONTINUE READING
