RESUMO

Objetivos. Presentamos los resultados del tratamiento de la patología oclusiva de la arteria femoral superficial (AFS) con el stent recubierto autoexpandible Viabahn –grupo endovascular (EV)-. Comparamos dichos resultados con los obtenidos con el bypass (BP) protésico a primera porción de poplítea –grupo BP-. Pacientes y métodos. Diseño retrospectivo. 46 pacientes (46 extremidades) se han intervenido en 5 años. Indicación de tratamiento: claudicación intermitente o isquemia crítica. Lesiones tratadas: B o C de la clasificación TASC (TransAtlantic Inter. Society Consensus) II. Seguimiento clínico y mediante estudio hemodinámico. En el grupo EV también mediante eco-Doppler. Se ha realizado un estudio descriptivo de permeabilidad de la serie y un análisis de factores pronósticos. Resultados. Grupo EV, 20 pacientes (43,5%), y grupo BP, 26 pacientes (56,5%). La indicación clínica fue mayoritariamente (85%) isquemia crítica en ambos grupos. Hubo diferencias en el tipo de lesión intervenida, TASC-B (60%) en el grupo EV y TASC-C (85%) en el grupo BP (p=0,002). En el grupo EV, 3 pacientes presentaron fracaso hemodinámico y 4 oclusiones (1 amputación mayor). En el grupo-BP se ocluyeron 4 injerto (1 amputación mayor). La permeabilidad primaria y secundaria al año para ambos procedimientos ha sido: grupo EV, 50 y 75%; grupo BP, 87 y 91%. Conclusiones. El tratamiento EV con el dispositivo Viabahn en lesiones tipo B en el sector femoropoplíteo ofrece buenos resultados inmediatos durante el seguimiento. Si bien los resultados no son tan favorables en lesiones tipo C, el tratamiento EV podría ser una alternativa al BP supragenicular en estenosis largas o en tándem, especialmente si se precisa recanalización de la AFS


Aim. We present the outcomes of treatment of occlusive pathologies in the superficial femoral artery (SFA) using the Viabahn self-expanding covered stent – the endovscular (EV) group. We compared these results with those obtained using a prosthetic bypass (BP) in the first portion of the popliteal –the BP group. Patients and methods. The study followed a retrospective design. Over a period of 5 years, surgery was performed on 46 patients (46 limbs). Indication for treatment: intermittent claudication or critical ischaemia. Lesions that were treated: B or C on the TASC (TransAtlantic Inter Society Consensus) II classification. Clinical monitoring by means of haemodynamic studies. Doppler ultrasound was also used in the EV group. Both a descriptive study of the patency of the series and an analysis of prognostic factors were carried out. Results. EV group, 20 patients (43,5%), and BP group, 26 patients (56,5%). The clinical indication was mostly critical inchaemia (85%) in the two groups. There were differences in the type of lesion that was treated by surgery: TASC-B (60%) in the EV group and TASC-C (85%) in the BP group (p=0.002). In the EV group, 3 patients presented haemodynamic failure and there were 4 occlusions (1 major amputation). In the BP group 4 grafts became occluded (1 major amputation). Primary and secondary patency at one year for the two procedures was: EV group, 50 and 75%; BP group, 87 and 91%. Conclusions. EV treatment with a Viabahn device in type B lesions in the femoropopliteal segment offers food outcomes, both immediately and during the follow-up. Although the results are not as favourable in type C lesions, EV treatment could be and alternative to above-the-knee BP in long or tandem stenoses, especially if recanalisation of the SFA is required
