2 Fig 1 Left, Anterior view of the preoperative anatomy. Right, Close-up posterior views of the abdominal coarctation region and the renal arteries. Graft material of the bypass and patch is presented in gray. Journal of Vascular Surgery  , e50-e51DOI: ( /j.jvs ) Copyright © Terms and Conditions

3 Fig 2 Left (top) and right (bottom) renal artery flow waveforms for preoperative thoracoabdominal bypass (TAB) and patch aortoplasty (PA). The biggest differences were observed in peak systole (0.3 second). Preoperative diastole-dominated flows normalized after surgery with a considerable decrease in high-frequency disturbances.
