[Endovascular treatment of atherosclerotic stenoses of the subrenal aorta].
The authors present results of endovascular treatment of subrenal aortic atherosclerotic stenoses. Between 1996 and 2001 they treated 9 patients (5 men, 4 women, mean age 57.4 years). Aortic stenoses were caused by an atherosclerotic process in all cases. In addition, in three patients iliac arteries were affected by sclerotic lesions. The endovascular procedure consists of predilatation performed by a small calibre angioplasty balloon catheter and implantation of a stent. Three times a balloon expandable stainless steel stent was implanted and self-expandible nitinol stents were used in the six cases. The primary technical success rate was 100%, no major complications were observed. One distal embolization was successfully resolved by intraarterial thrombolysis. Only one stent restenosis occurred after 36 months. It was successfully treated by implantation of a longer stent. That means that the primary patency of stented subrenal aorta during a mean follow-up period of 19 months was 87.5%. The claudication interval improved in six patients and three patients were symptom free. Endovascular therapy can be recommended for short sclerotic stenoses of the infrarenal aorta. This miniinvasive technique has a high technical and clinical success rate, favourable long-term patency and low complication rate.
