Oil contrast lymphography and respiratory function.

We reviewed our experience with direct oil contrast lymphography for pulmonary complications in more than 1500 lymphangiograms done since 1969. The vast majority of patients showed little subjective or objective (chest x-ray, pulmonary function test, and gas exchange) evidence of oil embolization even in those with mild to moderate cardiopulmonary disease. In 1% there was evidence on chest x-ray 24 hours after lymphography of tiny patchy infiltrates consistent with oil emboli. Although the indications for oil contrast lymphography have been sharply restricted with availability of newer imaging methods, it is nonetheless a safe and well-tolerated procedure even in patients with mild to moderate pulmonary dysfunction.
