Obstruction of the infrarenal portion of the abdominal aorta: results of treatment with balloon angioplasty.

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

“…27 PTA, which was initially introduced for aortic lesions in 1980 by Grollmann et al, 28 Velasquez et al, 29 and Tegtmeyer et al, 30 has been proposed as an alternative to surgery. Since then, several series have been published demonstrating successful results of PTA in localized stenoses involving the infrarenal aorta [5][6][7][8][9][10][11] as well as the aortic bifurcation. [5][6][7]10 Aortic PTA has a satisfactory immediate outcome, with initial technical success up to 95% to 100% 7,19,31 ; however, its mid-and long-term efficacy is frequently compromised due to restenosis.…”

“…1 Surgery, either with bypass graft or aortic endarterectomy, has been the traditional standard of care for infrarenal aortic occlusive disease, with good long-term patency rates of 70% to 75% at 10 years but a 5% to 10% early complication rate. [2][3][4] Percutaneous transluminal angioplasty (PTA) has been proposed as an alternative to surgery, and several series have demonstrated its safety and efficacy in localized stenoses of the distal infrarenal aorta [5][6][7][8][9][10][11] as well as in lesions involving the aortic bifurcation. [5][6][7]10 Stenting offers theoretic advantages over PTA, and its use has been established in several vascular beds, with excellent patency rates.…”

Outcomes of endovascular treatment of chronic total occlusion of the infrarenal aorta

“…Recent studies have shown improved clinical outcomes of endovascular therapy in complex iliac lesions involving the aortic bifurcation due to recent advances in devices and skills. [9][10][11][12][13][14][15] However, there are a paucity of data on immediate and long-term outcomes of endovascular treatments of chronic aortic occlusive disease. 16,17 We therefore sought to investigate the immediate and longterm outcomes of endovascular therapy in patients with chronic total occlusion of the infrarenal aorta.…”
