Abstract

In order to study the clinical efficacy of the metallic stent of the treatment of iliac arterial stenosis, the clinical and arteriographic findings of the 8 patients were retrospectively reviewed. All 8 patients were males with an age of 51 to 79. The Fontaine class for the functional status of lower extremities was II in 4 patients, III in 3 patients and IV in 1 patients. Self expandable Gianturco stent was inserted in 7 iliac arteries and balloon expandable Palmaz stent was inserted in 2 iliac arteries in the 8 patients. The indications for the metallic stent application were localized dissection with significant residual stenosis in 6sites, recoiling due to calcification in one case and eccentricity of the stenotic lesion in 2 sites. The deployment of the metallic stent was successful in all the cases to maintain the patency of iliac arteries with residual stenosis less than 30%. The Fontaine class was improved to I in 6 patients, II a in 1 patients IIb in another one. During the follow-up period of 3 to 14 months, none except one developed recurrence of the symptom. On the basis of our experience, we believe that metallic stent is safe and effective for the treatment of iliac arterial stenosis. However, we think that it is a complementary measure to the percutaneous transluminal angioplasty. The comparative study between different types of metallic stent and the long-term effect should be investigated further.
