AIM: To evaluate the short-term results of percutaneous stent placement in treating stenosis in the aorta caused by non-specific aortitis (Takayasu's disease). METHOD: Five patients were treated by this method, all of whom had uncontrolled hypertension, haemodynamically significant stenosis in the aorta and a clinically inactive disease. Stents were placed to treat an obstructing dissection in four and recurrent stenosis in one patient. All procedures were carried out via the percutaneous transfemoral route, utilizing self-expanding stents. RESULTS: The lesion was located in the thoracic aorta in three patients and in the abdominal aorta in two patients. The stenosis decreased from 81+/-2 to 7+/-3%, the pressure gradient fell from 97+/-5 to 9+/-2 mmHg, the blood pressure improved from 200+/-3/124+/-2 to 131+/-2/81+/-2 mmHg, and the drug requirement fell from 4+/-.2 to 1.3+/-.3 (P value for all <0.001). No complication was encountered. At follow-up at 13+/-4 months, all of the patients had improved clinically. Intimal hyperplasia within the stent was seen in two patients who underwent follow-up angiograms. CONCLUSION: Percutaneous aortic stenting is useful in treating selected patients with non-specific aortitis. Further information about the long-term behaviour of intimal hyperplasia and the response of stented segments to the aging process needs to be understood before elective stenting in this young patient population can be advocated.
