Resumen

BERTONI, Hernán G. et al. Endovascular Treatment of the Descending Thoracic Aorta: Mid-Term Results. Rev. argent. cardiol. [online]. 2007, vol.75, n.2, pp. 96-102. ISSN 1850-3748.

Objective The purpose of this paper is to assess and report our immediate and mid-term results with the endoluminal treatment of aneurysmal disease of the descending thoracic aorta, using an endoprosthesis or stent-graft. Material and Methods From August 1999 to August 2006, 74 consecutive patients (53 men and 21 women) were treated with an endovascular self-expanding stent-graft. Their mean age was 60 ± 14.8 years. Indications for treatment were: acute dissection in 8 patients (11%), chronic dissection in 31 patients (42%), intramural hematoma in 5 patients (7%), true aneurysm in 17 patients (23%), penetrating ulcer in 4 patients (5%) and posttraumatic pseudoaneurysm in 9 patients (12%). Results The implant of the device was successful in 73 patients (98.6%); no patient required surgical conversion. There were no cases of paraplegia or neurological deficit. Thirty-day mortality was 8.1% (n = 6). Median follow-up time was 33.5 months (range: 1-79 months) and overall survival was 84% (CI: 69-92%) and 91% (CI: 77-97%), according to whether early mortality was included or not. Ninetythree percent of patients (CI: 84-97%) were free from procedure- related complications. Most complications occurred during the first year of follow-up. Conclusions Endovascular treatment of the descending thoracic aorta with self-expanding stent-grafts is feasible and safe. Based on the low incidence of events reported in the surgical series published, we believe this is the procedure of choice in selected patients.
