Abdominal aortic aneurysms: preliminary technical and clinical results with transfemoral placement of endovascular self-expanding stent-grafts.

Abstract

Exclusion of AAA from circulation was feasible, safe, and clinically effective with the new stent-graft.

Endovascular Conversion Procedure for Failed Primary Endovascular Aortic Stent-Grafts

“…Initial technical success may be defined as successful introduction of the stent-graft system and exclusion of the aneurysm sac at the end of the procedure. Success rates of 89%-100% have been reported by various groups using different stent-graft systems [5,7,8]. Our own initial technical success rate for bifurcated stentgrafts is 95% [9].…”

MR Evaluation Ex Vivo and In Vivo of a Covered Stent-Graft for Abdominal Aortic Aneurysms: Ferromagnetism, Heating, Artifacts, and Velocity Mapping

“…The spiral CT studies were performed with a Toshiba Xpress/XS (Toshiba, Tokyo, Japan) imager, with a contrast agent, Omnipaque 300 mg I/ml (Nycomed, Oslo, Norway), in the in vivo studies. CT and CT angiography are the most commonly used methods for follow-up of endovascular treatment of AAA (4,7,13), and spiral CT is included in our follow-up after such treatment.…”

“…Recent studies have shown that this procedure may be a less invasive alternative to conventional surgery (3)(4)(5). However, procedure-related complications that may require secondary interventions necessitate a regular follow-up (6 -8).…”

Endovascular Aneurysm Repair

“…Medium-term results have been encouraging in cases fit for this treatment, [2][3][4][5][6][7][8][9][10][11][12][13][14] and complication rates have been moderate by comparison with standard surgery. 7,[15][16][17][18][19][20][21][22][23][24][25][26] Effective endovascular treatment results in a significant pressure reduction 27 and a shrinkage of the excluded aneurysm.…”
