WebJan 13, 2024 · Both failing to fully dilate the edges of a stent and dilating beyond the edges (“geographic miss”) are fairly common. 5 To minimize risk of edge trauma, the delivery balloon should generally be inflated to only 10 to 14 atm (the low end for somewhat oversized stents). Higher pressure inflation risks “dog-boning” and edge dissection ... WebThe deformation may have resulted in geographic miss of the original lesion or vascular damage to the region proximal to the stent, requiring additional stent implantation. Intravascular imaging with intravascular ultrasound or optical coherence tomography may provide additional useful insights, including whether stent apposition has been ...
