"Pseudo aortoiliac bifurcation" leading to significant plaque shifting in the endovascular treatment of an aortoiliac bifurcation lesion: a case report.

Plaque protrusion into the terminal aorta can form a "pseudo aortoiliac bifurcation", causing the wrong estimation of the height of the aortoiliac bifurcation; "angiographically", the highest point is not always the true bifurcation. Careful assessment of initial angiography to detect the true aortoiliac bifurcation and exact plaque position is essential to avoid unfavorable plaque shifting.
