@entity439 repair has been associated with changes in arterial stiffness, as estimated by pulse wave velocity ( @entity122 ). This marker is influenced by the medical status of the @entity1 , the elastic characteristics of the @entity439 wall, and the presence of intraluminal @entity715 . Therefore, in order to delineate the influence of the endograft implantation in the early post-operative period, we conducted non-invasively pulse wave analysis in a male @entity1 with an @entity1028 containing no intraluminal @entity715 , unremarkable past medical history, and absence of @entity3657 . The estimated parameters were the systolic and diastolic pressure calculated at the aortic level (central pressures), @entity122 , augmentation pressure (AP) and augmentation index (AI), pressure wave reflection magnitude (RM), and peripheral resistance. Central systolic and diastolic pressure decreased post-operatively. @entity122 showed subtle changes from 11.6 to 10.6 and 10.9   m/s at 1-week and 1-month, respectively. Accordingly, the AI decreased from 28 to 14% and continued to drop to 25%. The AP decreased gradually from 15 to 6 and 4   mmHg. The wave RM dropped from 68 to 52% at 1-month. Finally, the peripheral resistance dropped from 1.41 to 0.99 and 0.85   dyn   *   s   *   cm(-5). Our example shows that the implantation of an aortic endograft can modify the pressure wave reflection over the aortic bifurcation without causing significant alterations in @entity122 .
