[Percutaneous treatment of thoracic aorta diseases. A multidisciplinary approach].

INTRODUCTION AND OBJECTIVES: The purpose of this study was to evaluate the experience of a multidisciplinary team in the percutaneous treatment of thoracic aorta disease.

PATIENTS AND METHOD: Between December 2001 and January 2004, 15 patients were selected for percutaneous treatment at the Thoracic Aorta Unit of the Hospital Universitario Central de Asturias. The motives for stent implantation were: degenerative aneurysm (n=7), acute dissection (n=4), penetrating atherosclerotic ulcer (n=1), posttraumatic aneurysm (n=2) and postsurgery pseudoaneurysm (n=1). Four procedures were considered emergencies. Another two patients underwent prior surgery of the supra-aortic branches. Previous computed tomographic angiography and arteriography were performed, and in complex cases of dissection, magnetic resonance imaging was used. All stent placement procedures were performed in the hemodynamics laboratory. All patients underwent computed tomographic angiography during follow-up.

RESULTS: Stent positioning was technically successful in 14 patients. The mean length of aortic coverage was 230 +/- 110 mm (range 110-440 mm). No intraoperative deaths occurred. There was one in-hospital death. Transient postimplantation syndrome was presented in three patients. Two type I endoleaks, one type II endoleak and one thrombosis of the superior mesenteric artery were found on computed tomographic angiography at one month. One type III endoleak and one type II endoleak were found during subsequent follow-up.

CONCLUSIONS: Endovascular stent-grafting is a valid alternative in the treatment of aortic disease in high-risk patients. Coordination between different medical specialties and appropriate selection of patients are needed. Long-term follow-up is necessary to ensure the usefulness and efficacy of the procedure.
