Partial renal coverage in EVAR causes unfavorable renal flow patterns in an infrarenal aneurysm model [PDF]
J.Vasc.Surg 67 (2018) 1585-1594, 2019 Objective: To achieve an optimal sealing zone during EVAR, the intended positioning of the proximal end of the endograft fabric should be as close as possible to the most caudal edge of the renal arteries. Some endografts exhibit a small offset between the radiopaque markers and the proximal fabric edge.
