title: [Translumbar aortography by catheter technique. Methods, indications and value (author's transl)].
abstract: 400 examinations performed during the last three years by TLA (only catheter technique) were subjected to critical analysis and studied particularly in respect to the rate of complications. We observed 13 complications (3,25%) of moderate severity, including 3 large hematomas (documented by CT), 3 paravasations and 7 dissections, but no fatal complications. Two (0,5%) of these complications had clinical evidence. The advantages of the catheter technique of TLA are described. Injections through rigid metal cannula should be avoided because of the high incidence of complications (mainly the increased risk of dissection). Downstream injection resulted in excellent visualization of peripheral occluding vascular disease. Upstream injection should be preferred to demonstrate the major abdominal arteries as well as supraceliac collateral circulation in the case of high Leriche syndrome. The low or intermediate puncture of the aorta is preferable to facilitate caudad direction of the catheter and to diminish the risk of damaging other vessels or puncturing an organ.
