Resumen
Introducción

La aparición de aneurismas en los injertos vasculares de vena umbilical humana se describió por primera vez en 1982. El tratamiento más habitual ha sido la cirugía. La llegada de las técnicas endovasculares ha incrementado las posibilidades terapéuticas que podemos ofrecer al paciente así como ha minimizado las complicaciones de la cirugía.

Caso clínico

Paciente de 76 años con isquemia crónica de extremidades inferiores, intervenido en varias ocasiones (simpatectomía lumbar izquierda, bypass femoropoplíteo izquierdo a primera porción con politetrafluoroetileno en 1989 y bypass femoropoplíteo izquierdo a tercera porción con bioprótesis homóloga en 1994). Durante el seguimiento apareció dilatación aneurismática en aloinjerto diagnosticado mediante eco-Doppler. Se completó el estudio con tomografía axial computarizada (TAC) y angiografía por resonancia magnética. Como tratamiento, se implantó stent recubierto Viabahn de 8 ×100mm, quedando el aneurisma completamente excluido. A los seis meses de seguimiento no se aprecian endofugas ni migración, y permanece permeable según eco-Doppler y TAC.

Conclusión

El avance en las técnicas endovasculares permite un tratamiento rápido y sencillo de los aneurismas de injertos infrainguinales, especialmente útil en pacientes técnicamente complicados o de alto riesgo quirúrgico. [ANGIOLOGÍA 2006; 58: 57-61

Summary
Introduction

The appearance of aneurysms in human umbilical vein vascular grafts was first reported in 1982. Surgical intervention has been the most common treatment until now. The advent of endovascular techniques has expanded the possible therapeutic options that we can offer the patient, while at the same minimising the complications that can result from the intervention.

Case report

We report the case of a 76-year-old patient with chronic ischaemia in both lower extremities who had been submitted to surgery on several occasions (left-side lumbar sympathectomy, a femoral-popliteal polytetrafluoroethylene bypass in the first portion of the left-hand side in 1989 and a femoral-popliteal bypass in the third portion with a homologous bioprosthesis in 1994). During the follow-up an aneurysmal dilatation appeared in the allograft, as diagnosed by Doppler ultrasound recording. The study was completed with computerised axial tomography (CAT) and magnetic resonance angiography. Treatment consisted in the placement of an 8 ×100mm Viabahn covered stent, after which the aneurysm was completely excluded. At three months' follow-up no endoleaks or migration were detected and, according to Doppler ultrasound and a CAT scan, patency is preserved.

Conclusion

The progress being made in endovascular techniques allows fast, simple treatment of aneurysms in infrainguinal grafts, which is especially useful in technically complicated patients or those with a high surgical risk. [ANGIOLOGÍA 2006; 58: 57-61]
