Midterm results of endovascular stent graft treatment for descending aortic aneurysms including high-risk patients.
METHODS
21 patients (17 men, 4 women; mean age 66.1 years, range 29-90 years) with 15 true aneurysms, and 6 type B-dissections were treated by implantation of a Talent Endoluminal Stentgraft System from February 2000 to July 2003. In 3 cases it was necessary to overstent the left subclavian artery, in 1 case to overstent the left common carotid.


RESULTS
2 patients (9.5%) died during the first 30 days (1 myocardial infarction, 1 pneumonia). Two patients (9.5%) suffered from cerebral ischemia and needed revascularisation. No paraplegia, no stroke occurred. One endoleak required additional stenting. No patient needed conversion. Follow-up, average 25.4 months (range 0-39), was 100% complete. During this another two patients died of myocardial infarction i.e. 9.5% (the above mentioned endoleak, but no late migration were detected in the remaining patients). In all cases the graft lumen stayed patent.


CONCLUSIONS
Treatment of descending thoracic aortic aneurysm with an endovascular approach has acceptable mortality and morbidity-rates even in high risk patients. Procedural overstenting of the subclavian artery requires subclavian revascularisation in a minority of cases.
