Endovascular stent-graft treatment of thoracic aortic syndromes: A 7-year experience

Thoracic aortic diseases (TAD) are relatively frequent conditions associated with high mortality. Recently, several reports have demonstrated the safety and efficacy of endovascular stent-graft (EVG) placement for TAD as an alternative to open surgery. We report our experience in management of thoracic aortic syndrome on 56 consecutive patients with TAD that underwent endovascular stent-graft repair. MDCT angiography was used in all patients to provide preprocedure evaluation and measurements. In particular it is necessary to evaluate the proximal and distal landing zones of the stent-graft. All EVGs in our series were placed successfully. Conversion to open surgery was never required. Six patients (10.7%) died early after the stent-graft deployment. During follow-up four more patients died. The endoleak rate was 16.7% (no.10 pt). We did not observe any case of paraplegia. The present study shows the efficacy of EVG in the long-term follow-up, with an overall survival of 82.1%, which is comparable to that reported in recent studies. In conclusion this technique is emerging as an alternative approach in the treatment of TAD because this approach offers a less invasive therapeutic option to standard surgical techniques, even in patients who have associated diseases that make them poor surgical candidates.
