If however, the angiography with the contrast medium indicates that an edge dissection has occurred, then the fixed guidewire stent delivery catheter would be left in place with its balloon deflated. The Luer fitting at the proximal end of the stent delivery catheter would then be cut off and a rescue in the form of a rescue catheter would be advanced over the stent delivery catheter. The rescue catheter would then be advanced until its distal end extended distally beyond the site of the edge dissection. The fixed wire stent delivery catheter would then be pulled out of the body through the rescue catheter and a conventional guidewire would be inserted through the rescue catheter. The rescue catheter would then be removed leaving the guidewire in place. A conventional stent delivery catheter would then be used to deliver a second stent to the site of the intimal dissection at the edge of the first implanted stent, thus repairing the dissection.
