ABSTRACT

Background:

Endovascular repair of aortic aneurysms is less invasive than the traditional surgical approach.

Aim:

To evaluate the early and mid-term results of aorto-iliac aneurysm endovascular repair. Material and

Methods:

Analysis of 28 patients aged 59 to 86 years (22 males), subjected to an endovas-cular repair of aorto-iliac aneurysms between 2007 and 2012.

Results:

The follow up period of patients ranged from 1 to 65 months. A tri-modular bifurcated prosthesis was installed in 25 patients. A bi-modular bifurcated prosthesis was installed in one patient, an aorto uni iliac prosthesis was installed in one patient; in other patient, a straight endoprosthesis was installed after an abdominal visceral disconnection. In cases of associated iliac aneurysms, unilateral iliac embolization was carried out in seven patients and bilateral embolization in one patient. In one case, the sealing of the hypogastric artery was achieved leaning the prosthetic branch on the hypogastric artery ostium. One patient died 31 days after the operation due to multiple organ failure. One patient died 24 months after surgery due to a gallbladder cancer and other patient died 36 months after surgery due to a rectal cancer. The long-term follow-up showed the presence of type 2 endo-leaks in two patients. The aneurysm decreased in size in 83 percent of patients after 2 years of follow-up. In five patients, a non-progressive laminar parietal thrombosis inside the endoprosthesis, was observed in the immediate postoperative period. It was initially treated with oral anticoagulants.

Conclusions:

Endovascular repair of aorto-iliac aneurysms is safe and effective in patients with appropriate anatomical conditions, if a skilled surgical team is available...
RESUMEN

Objetivo:

Evaluar los resultados iniciales y en el mediano plazo de la reparación endovascular de los aneurismas del sector aorto-ilíaco. Material y

Método:

Revisión de una serie clínica de pacientes operados en forma consecutiva por vía endovascular en el Hospital Dr. Eduardo Pereira de Valparaíso por aneurismas del sector aorto-ilíaco desde 2007 al 2012 con seguimiento actualizado.

Resultados:

Se trata de 28 pacientes (22 varones), una edad promedio de 72,5 años (rango 59-86) y un seguimiento promedio de 27,4 meses (rango 1-65 meses). Los pacientes fueron seleccionados de acuerdo a la anatomía aorto-ilíaca y su estado general. A 25 pacientes se les instaló una prótesis bifurcada tri-modular, a un paciente una prótesis bifurcada con sólo dos módulos, a otro paciente una prótesis aorto uni ilíaca, y a una paciente una endoprótesis recta luego de una desconexión visceral abdominal. Un paciente fallece a los 31 días después de operado por falla orgánica múltiple y otros dos pacientes fallecen a los 24 meses a causa de un cáncer vesicular y a los 36 meses por un cáncer rectal. El seguimiento alejado evidenció ausencia de endofugas tipo 1, 3 ó 4 y una endofuga tipo 2 en dos pacientes, que no han requerido ninguna intervención.

Conclusión:

La reparación endovascular de los aneurismas del sector aorto-ilíaco es segura en el corto y mediano plazo, en pacientes con las condiciones anatómicas apropiadas en un centro quirúrgico adecuadamente equipado...
