[Countercurrent aortography by contrast injection into a peripheral artery]. / Aortografía a contracorriente por inyección de contraste en arteria periférica.

Countercurrent aortography performed through left brachial artery in 8 children, aging 27 days to 42 months. Systemic-pulmonary anastomosis was possible to be assessed in 3 out of 4 cases, even in one aging 42 months. Aortic coarctation could be evaluated in another 3 patients. In the last case with a clinical suspection of vascular ring, countercurrent aortography disclosed an anomalous right subclavian artery. We concluded that the procedure is safe and useful to assess some conditions involving thoracic aorta, even in older children.
