Abstract Powers, W. F. and Swyer, P. R. (Research Institute of the Hospital for Sick Children, and the Department of Pediatrics, University of Toronto, Toronto, Canada). Diminished limb blood flow in infants with transposition of the great vessels: An adaptation to chronic hypoxia? Acta Paediatr Scand, 66:205, 1977.—Calf blood flow was measured by venous occlusion plethysmography using a mercury in rubber strain gauge in infants with transposition of the great vessels. (TGV), and in comparable infants free from cardiopulmonary disease. Resting calf blood flow in the infants with TGV was 3.610.8 ml/100 ml/min, while in the control group flow was 6.8±2.3 ml/100 ml/min, a highly significant difference. We postulate that newborns with TGV decrease their resting calf flow in response to chronic hypoxia.
