ABSTRACT The aim was to evaluate a wholly endovascular approach to the repair of thoracoabdominal aortic aneurysm (TAAA).
Six patients (median age 71 years) underwent wholly endovascular repair of TAAA (maximum diameter 56-85 mm) employing individually customized endografts. Procedures were performed under general anaesthesia, with spinal drainage in five patients. Patients were followed by serial computed tomography, plain radiography and duplex imaging for a median of 17 (range 8-44) months.
All grafts were deployed as intended, with preservation of all target vessels. There were no postoperative deaths, strokes or paraplegia. One patient suffered a silent myocardial infarction. In two patients a persistent paraostial endoleak was treated by further balloon dilatation of the stent within the endograft fenestration. Imaging before discharge confirmed aneurysm exclusion in all patients. Two patients required late secondary intervention to abolish endoleaks due to side-branch disconnection. One patient suffered late occlusion of the coeliac axis without clinical sequelae, and late occlusion of a solitary renal artery in another resulted in dependence on dialysis. There have been no late deaths and all aneurysms remain excluded.
Wholly endovascular TAAA repair is relatively safe, but long-term follow-up is required to establish its durability.

    ABSTRACT: En la última década hemos sido testigos de la transformación del tratamiento de pacientes con vasculopatías. A medida que los cirujanos vasculares han adquirido habilidades cada vez más avanzadas basadas en la manipulación de catéteres, al igual que un mayor abordaje a dispositivos más sofisticados, ha tenido lugar una rápida transición hacia las técnicas mínimamente invasivas. Los pacientes que no son candidatos a una revascularización percutánea, o los considerados en riesgo prohibitivo para la corrección quirúrgica tradicional, pueden beneficiarse de un tratamiento híbrido, una combinación de cirugía abierta y endovascular con una disminución de la morbilidad y la mortalidad. En la presente revisión se examinan las aplicaciones de los procedimientos híbridos para tratar a pacientes con claudicación invalidante e isquemia crítica de la extremidad, patología del cayado aórtico, aneurismas toracoabdominales, estenosis de la carótida extracraneal y coronariopatía.

    ABSTRACT: Aortic aneurysms are classified as complex based on their extent and involvement of side branches. Complex aortic aneurysms include arch, thoracoabdominal, juxtarenal and suprarenal aortic aneurysms. Open surgical repair carries high morbidity and mortality beyond large tertiary care centers. During the last decade, numerous technological advances have allowed incorporation of side branches using hybrid and total endovascular techniques. Fenestrated and branched endografts have been widely applied to treat patients with complex aneurysm anatomy. Newer stent graft designs are currently under clinical investigation offering an off-the-shelf alternative to custom-made stent grafts for patients with complex aortic aneurysms. Alternatively, a number of endovascular techniques have been described including chimney, snorkel, periscope and sandwich stent grafts. This article summarizes the current status of hybrid and total endovascular techniques to repair of thoracoabdominal, juxtarenal and suprarenal aortic aneurysms.

    ABSTRACT: La dernière décennie a été le témoin d'une transformation des soins destinés aux patients atteints de pathologie vasculaire. Il y a eu une transition rapide vers des techniques moins invasives liée à une progression concernant l'habileté des opérateurs pour les techniques endovasculaires et leur accès à des matériels plus récents et plus sophistiqués. Les patients qui ne sont pas de bons candidats à une revascularisation percutanée complète ou ceux pressentis comme étant à risque prohibitif pour une revascularisation chirurgicale traditionnelle pourraient tirer bénéfice d'une thérapie hybride, combinant la chirurgie ouverte au traitement endovasculaire, avec l'opportunité d'une revascularisation complète en diminuant la morbidité et la mortalité. Cette revue examine l'applicabilité des procédures hybrides pour le traitement des patients présentant une claudication intermittente invalidante, une ischémie critique de membre, une pathologie de la crosse aortique, un anévrysme thoraco-abdominal, une pathologie de la carotide extra crânienne et une coronaropathie.
