Technical considerations in aortography for the investigation of lower limb ischaemia--results from a postal survey.

Eighty-eight radiologists who performed aortography responded to a postal questionnaire. Three-quarters used the transfemoral catheter method and a quarter routinely performed translumbar aortography. The majority used low-osmolality contrast media. Most translumbar aortograms are performed under general anaesthesia and most transfemoral techniques under sedation and/or analgesia. Details of catheters, guide wires and methods of injection were also obtained from the survey.
