[Percutaneous stents for the treatment of stenosis of descending aorta].
Stenotic processes of the descending aorta lead to a transstenotic gradient with either risk of proximal hypertension especially affecting the cerebral circulation combined with the risk of distal malperfusion. This article describes the technique of percutaneous stenting of suprarenal aortic stenosis in two patients with different genesis of aortic obstruction in whom operative correction was refused due to elevated surgical risk. The first patient (female, 38 years) suffered from aortic stenosis at the thoracoabdominal level revealing a residual lumen of 3 mm. The second patient (male, 71 years) had a chronic type B aortic dissection and developed dynamic compression of true lumen and thus peripheral malperfusion. Both patients were treated successfully with percutaneous implantation of self-expanding stents. During the follow-up of 6 and 10 months, respectively, both patients were free of any symptoms. The technique of percutaneous stenting of static and dynamic stenotic processes of the aorta led to excellent mid-term results. Long-term results of large patient cohorts are not available yet; however, all patients subjected to such a palliative procedure should be followed in structured registries in an effort to standardize the concept and develop therapeutic recommendations.
