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 2018 68, e50-e51DOI: (10.1016/j.jvs.2018.06.031) Copyright © 2018 Terms and Conditions

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.
