PURPOSE: The purpose is to present results of endovascular exclusion (stent-graft treatment) of @entity439 of the descending thoracic aorta both in elective cases and in emergencies. METHODS: Indications for stent-graft treatment were dependent on multislice angio-CT evaluation revealing a proximal neck of at least 10 mm between the left common carotid artery and the onset of @entity439 . All stent grafts were inserted in the operating room; 43 transfemoral, 2 transiliac. The stent grafts used were Corvita, Stenford, Vanguard, AneuRx, Talent, and Excluder. Deployment was achieved under fluoroscopic control, @entity1070 were checked for with D S A on the operating table and postoperatively by angio-CT. Long-term follow-up consisted of evaluation with angio-CT after 6 and 12 months, and from there on once a year and with plain chest X-rays. Follow-up was achieved in all @entity1 . RESULTS: Mean follow-up is 21 months (1-66); 30-day mortality is 3/45, no permanent @entity51 . Thirty @entity1 were treated electively, 15 with contained @entity397 . Left subclavian artery overstenting proved to be necessary in 12 @entity1 for proper proximal sealing of the @entity439 , @entity1070 were observed in 10 @entity1 , one early conversion, 7 proximal extension cuffs, one sealed spontaneously, one still at risk. Among @entity1 where LSA had been overstented only one wanted a transposition, all others did well without left-hand @entity63 or @entity3526 . CONCLUSION: Endovascular treatment is less invasive and has reasonable mortality and morbidity but is limited to well-defined morphologies. Mid-term results are promising but it has to be observed whether these will translate into long-term durability.
