Endoluminal stent-grafts for infrarenal abdominal aortic aneurysms
Article Abstract:
A surgical stent may be effective as an alternative to surgery in patients with an aortic aneurysm. An aneurysm occurs when the wall of an artery becomes weak and balloons out. Researchers treated 154 patients with an aortic aneurysm by using a catheter to push a polyester stent through the femoral artery in the leg up to the aortic aneurysm. The stent is a hollow cylinder that is used to support arteries. The treatment was successful in over 80% of the patients. Ten percent experienced a major or minor complication. Only one patient died following the procedure.

Current therapy for infrarenal aortic aneurysms
Article Abstract:
Endovascular placement of surgical stents may revolutionize the treatment of aortic aneurysms but long-term studies are needed. Stents are small cylindrical devices placed inside an artery to treat aneurysms, which occur when the wall of the artery weakens and begins to balloon out. A 1997 study found the technique to be effective in over 85% of the patients in which it was tried, but the follow-up period was fairly short. This technique promises to reduce mortality rates from these aneurysms and could be performed as an outpatient procedure.

Treatment of ostial renal-artery stenoses with vascular endoprostheses after unsuccessful balloon angioplasty
Article Abstract:
A surgical stent may effectively treat renal artery stenosis, which can cause high blood pressure. Renal artery stenosis occurs when plaque blocks this artery in the kidney. Researchers treated 68 patients with renal artery stenosis with stainless steel stents, which are small, hollow cylinders placed in the artery to keep it open. The technique was successful in all patients, and even lowered blood pressure in 16%. There were no major complications and only 3 minor ones. Balloon angioplasty is not always successful in these patients.
