RESUMEN

This systematic review focuses on the 30-day mortality associated with open surgery and fenestrated endografts for short-necked (<15 mm) juxtarenal abdominal aortic aneurysms. A search for studies published in English and indexed in the PubMed and Medline electronic databases from 2002 to 2012 was performed, using “juxtarenal abdominal aortic aneurysm” and “treatment” as the main keywords. Among the 110 potentially relevant studies that were initially identified, eight were in accordance with the inclusion criteria in the analysis. Similar outcomes for open and endovascular repair were observed for 30-day mortality. No differences were observed regarding the secondary outcomes (duration of surgery, hospital stay, postoperative renal dysfunction and late mortality), except that the late mortality rate was significantly higher for the patients treated with open repair after a median follow-up of 24 months. Fenestrated endografting is a viable alternative to conventional surgery in juxtarenal abdominal aortic aneurysms with a proximal neck <15 mm.

RESUMEN

El tratamiento endovascular de los aneurismas de aorta abdominal es una alternativa a la cirugía abierta para pacientes de alto riesgo. Consiste en la exclusión del saco aneurismático mediante la interposición de una endoprótesis colocada por vía femoral. El tratamiento endovascular no puede ser utilizado en todos los pacientes. Una limitación frecuente la constituye el nacimiento de una arteria visceral desde el saco aneurismático. Para contrarrestar esta limitación recientemente se han desarrollado endoprótesis fenestradas que presentan orificios que se corresponden con el nacimiento de las arterias involucradas en el aneurisma evitando su oclusión, permitiendo de esta manera el tratamiento endovascular. En esta comunicación se presenta un caso de tratamiento endovascular de un aneurisma de aorta abdominal mediante la colocación de una endoprótesis fenestrada en un paciente cuya arteria renal izquierda nacía directamente del saco aneurismático.


Endovascular treatment of the abdominal aortic aneurysm is consider an alternative to open surgery for high risk patients. Its goal is to exclude the aneurysm from the circulation by using an endoprothesis introduced from a femoral approach. Patients must be strictly selected to avoid possible complications. The most frequent limitation is related to anatomic contraindications such as visceral arteries involved in the aneurysm. Fenestrated endograft have been recently developed to allow endovascular treatment when anatomic features contraindicate classic endovascular procedures. Fenestrated endograft have holes that match with the origin of the visceral arteries maintaining its potency. In this paper we report the endovascular treatment of an abdominal aortic aneurysm by using a fenestrated endoprothesis in a patient whose left renal artery is originated from the aneurysm.
