Primary stenting for aortic lesions: From single stenoses to total aortoiliac occlusions

A, Digital subtraction angiography demonstrates isolated stenosis at the mid-portion of the infrarenal aorta transversed with a long sheath. B, Successful deployment of a balloon-expandable aortic stent without residual stenosis.

A, Preprocedural digital subtraction angiography demonstrates total aortobiiliac occlusion. B, Treatment with two aortic and iliac stents deployed contiguously. C, At 9 months postoperatively, the aortic and iliac stents remain widely patent.

A, Total aortobiiliac occlusion treated successfully with primary stenting of the (B) infrarenal aorta and common iliac arteries.

Kaplan-Meier life-table analysis of primary patency after stenting of aortic localized stenoses and total occlusions.

A, Drawing shows eccentric calcified aortic stenosis. B, Placement of a self-expanding stent, centered on the lesion, with adequate length achieving complete deployment of its edges in healthy aortic segments. C, Successful postdilation of the stented lesion. D, Inappropriate placement of a noncentered, small-length, self-expanding stent results in (E) difficulties in subsequent balloon catheter advancement due to incomplete deployment of its distal edge.
