          Abstract

          Resumen El tratamiento endovascular del aneurisma de aorta abdominal (AAA) puede tener complicaciones durante su seguimiento; entre ellas, las endofugas. Presentamos el caso de un paciente de 55 años que fue tratado de manera programada con endoprótesis aórtica bifurcada por un AAA infrarrenal de 84 mm de diámetro. El paciente presentó una reducción progresiva del saco aneurismático hasta un diámetro de 42 mm tras treinta meses de seguimiento. Después de cuatro años de seguimiento y sin signos sugestivos de complicaciones en la ecografía de control, se encuentra un leve crecimiento del saco (46 mm), sin evidencia de endofugas. Ante el hallazgo, se solicita TAC en la que se evidencia crecimiento del saco de hasta 55 mm de diámetro, sin presencia de fugas. En un nuevo estudio a los 3 meses, el saco ha sufrido una rápida expansión, hasta 73 mm de diámetro, sin evidencia de fugas. Ante los hallazgos y el riesgo de rotura, se planifica reparación abierta por endofuga tipo V. Se encuentra una fístula apendicular comunicada con un saco aneurismático de aspecto inflamatorio en la zona de contacto aórtico-apendicular. El paciente evolucionó favorablemente con antibioticoterapia prolongada. A los siete meses no ha presentado complicaciones clínicas ni en las pruebas de imagen.

          Abstract Endovascular aneurysm repair (EVAR) is an important treatment option for abdominal aortic aneurysms. An endoleak is a common complication following EVAR. A 55-year-old man underwent elective EVAR with a bifurcated graft for a 84 mm infrarenal abdominal aortic aneurysm (AAA). Follow-up a showed appropriate reduction of the AAA to 42 mm. A duplex ultrasound at fourth year follow up showed an increase of AAA sac size to 46 mm with no observable endoleaks. A subsequent CTA showed an increase of AAA sac size to 55 mm with no observable endoleaks. A new CTA at 3 months follow up showed a rapid increase of AAA sac size to 73 mm with no observable endoleaks. We decided to perform open surgery. We found appendicular fistula in contact with aneurysmal sac with an inflammatory appearance in the aortic-appendicular contact area. The patient was successfully treated and no severe complications occurred during the 7 months follow-up.

          Late conversion of aortic stent grafts.

          The frequency of late removal of endovascular abdominal aortic repair (EVAR) parallels the rise of endovascular aortic repair. Evaluation of outcomes for EVAR explants may identify risks for complications and alter clinical management.

            Endotension following endovascular aneurysm repair.

            Endovascular aneurysm repair (EVAR) is a new and minimally invasive alternative to open repair for patients with abdominal aortic aneurysm (AAA). Soon after its introduction in 1990, it was recognized that EVAR had potential and distinct advantages in the elective and emergency settings. However, long-term follow-up has shown enlargement of the AAA in a substantial percentage of patients who underwent EVAR with the original-permeability Excluder. Of interest is that sac expansion frequently occurs in the absence of endoleak, often referred to as endotension. The pathophysiology of endoleak is beginning to be elucidated and its management is ready to be established, while controversy still exists about the etiology and clinical consequences of endotension. Fortunately, the incidence of endotension is decreasing and it appears that AAA expansion after EVAR with the original Excluder can be arrested by endovascular relining with a low-permeability Excluder endoprosthesis. The aim of this brief review is to provide historical perspective and a good understanding of the etiology, diagnosis, and management of endotension.
