Primary Endovascular Stent Placement for Focal Infrarenal Aortic Stenosis: Long-term Results

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

“…So far, only a limited number of studies have reported the outcomes of endovascular therapy for stenotic or occlusive disease of the infrarenal aorta. Earlier studies, which included mostly patients with stenotic lesions rather than occlusive aortic disease, reported relatively high patency rates of 75% to 89% at 3 to 5 years, [21][22][23][24] which are comparable with those of surgical treatments. 5,25,26 Two recent studies reported the outcomes of endovascular therapy in study populations that exclusively included patients with chronic total occlusion of the infrarenal aorta.…”

Endovascular treatment as first line approach for infrarenal aortic occlusive disease

“…10 To increase the evidence relating to endovascular treatment, we reported our early and late results for primary stenting in this disease.…”

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

“…Clinical patency was defined as the continued absence or improvement of symptoms and hemodynamic patency as stenosis Ͻ50% at DUS scan. 16,17 During the latter, the whole stented segment was scanned to locate areas with high peak systolic velocities, which were then compared with the velocities recorded immediately upstream and downstream. The value of the highest proportional velocity change was used as the criterion for stenosis grading.…”

“…[5][6][7]10 Stenting offers theoretic advantages over PTA, and its use has been established in several vascular beds, with excellent patency rates. 12 In the infrarenal aorta, however, only a small number of studies to date have evaluated the results of primary stenting for localized stenoses, [13][14][15][16] whereas total aortic occlusions have been conventionally considered as a relative contraindication for endovascular therapy. In this series, we report our experience with primary stenting for aortic occlusive disease, ranging from single infrarenal aortic stenoses to extended chronic total aortobiiliac occlusions.…”
