Histology and electron microscopy of explanted bifurcated endovascular aortic grafts: evidence of early incorporation and healing.

Purpose: To report an examination of explanted bifurcated endovascular aortic grafts for histologic evidence of early healing and incorporation.

Method: Two bifurcated endovascular aortic grafts composed of polycarbonate urethane and Elgiloy wire were explanted 42 and 21 days after successful endovascular exclusion of abdominal aortic aneurysms. Both patients expired from causes unrelated to endograft deployment.
