Figure 1a. Duplex US images obtained 1 month after implantation of the Dacron-covered stent-graft in the superficial femoral artery demonstrates a hypoechogenic rim (between crosshairs) around the stent-graft. (a) Cross-sectional and (b) longitudinal views of the superficial femoral artery show the Dacron-covered stent-graft in situ.

Figure 2a. Restenosis after successful primary implantation of two overlapping Dacron-covered stent-grafts for treatment of a long lesion (10 cm) in the superficial femoral artery. Lumen narrowing typically occurred at the edges of the stent-graft in these anteroposterior images. (a) Preintervention anteroposterior contrast material-enhanced angiogram (left) shows superficial femoral arterial stenosis. Postintervention angiograms (second and third from left) depict the ends of the stent-grafts (arrows). Six-month follow-up angiogram (right) shows restenosis at the edges of the stent-grafts (arrowheads). (b) Magnification angiograms of the superficial femoral artery obtained 6 months after implantation of two overlapping Dacron-covered stent-grafts depict restenosis (arrowheads) at the edges of the endograft.

Figure 3. Graph shows cumulative primary and secondary patency rates in 30 patients after implantation of a Dacron-covered stent-graft. Patency data at 36 months or later were obtained only in cases of ankle-brachial index deterioration or clinical suspicion for restenosis. Solid line = primary patency rate, dashed line = secondary patency rate. Numbers above the lines are the number of patients at risk.
