Does significance of initial aortic aneurysm pressure sensor readings vary with aortic endograft design?
The Talent graft has significantly higher pulse ratios following endograft implantation despite having no angiographic evidence of endoleak when compared to the Zenith and Excluder grafts. However, the pulse ratios decreased to levels similar to Zenith and Excluder within 30 days of endograft implantation. This suggests that the Talent endograft may have increased porosity initially. If pulse ratios do not appropriately decrease immediately after device implantation, further angiographic imaging may not be necessary if no obvious endoleak is seen.
In an ex vivo porcine liver, preinjected fluids do not benefit microwave ablation as those in radiofrequency ablation.
