`
`Successful Use of the GuideLiner
`Catheter to Treat Sequential
`Distal Carotid Artery Stenoses
`
`PHYSICIAN
`
`George Petrossian, MD
`St. Francis Hospital, Roslyn, New York
`
`PRESENTATION
`
`The patient is a male with a history of hypertension and
`hypercholesterolemia. He has a remotehistory of neck
`surgery for a parotid tumor, followed byradiation.
`
`Five months ago, he presented with a left hemispheric
`CVA, with moderate residual arm weakness. Angiography
`demonstrated a 50% ulcerated right internal carotid stenosis.
`The left carotid contained a proximal 90% stenosis at the
`origin, an 80% tubular mild left ICA stenosis distal to an
`angulated segment, and an 80% stenosis in the distal left ICA
`(petrous segment). At that time, an 8mm x 10mm,tapered
`Xact® stent was placed at the proximal stenosis with distal
`protection.
`
`Two weeksago, the patient developed one hour of severe
`right arm weakness which resolved. He then underwent
`repeat carotid angiography.
`
`INITIAL FINDINGS
`
`Carotid angiography demonstrated a stable 50% ulcerated
`plaque within the right ICA. The left ICA proximal stent was
`widely patent. The mid left ICA contained an 80% tubular
`stenosis and the distal left ICA (petrous segment) had
`progressed and contained a 95% stenosis (Figure 1).
`
`TREATMENT
`
`Without distal protection, a 3mm x 15mm balloon was used
`to perform PTA of the 2 distal stenoses (Figure 2). A 7mm x
`20mm Xact stent would notcross the distal lesion, and was
`
`deployed at the more proximal lesion, with a similar 7mm
`x 20mm stent placed just proximally. A significant residual
`stenosis was present at the distal stent margin as well as the
`mostdistal lesion in the petrous segment. Further attempts
`to cross the remaining lesions with a 2.0mm balloon over a
`0.014" guidewire were unsuccessful.

`TREATMENT WITH GUIDELINER CATHETER
`
`A 0.014" BMW 300cm guidewire was placeddistally in the
`left ICA and the GuideLiner catheter was advanced into the
`
`stented segmentof the left ICA (Figure 3). A 2mm x 15mm
`OTW balloon crossed the distal lesion with GuideLiner
`
`support and a 300cm Wiggle™ guidewire was placeddistally
`after removal of the BMW guidewire.
`
`A3.5mm x 15mm bare metal stent and a 4.5mm x 18mm bare
`
`metal stent were deployed distally (Figure 4) within the left
`ICA and postdilated (Figure 5). The end result was a widely
`patent left ICA (Figure 6).
`
`CONCLUSION
`
`The GuideLiner catheter provided the support necessary to
`advanceballoon and stent catheters to the distal left ICA
`
`in a patient with prior radiation, vessel tortuosity and prior
`stent implantation. Without the GuideLiner catheter, this
`procedure would have been unsuccessful.

`GuideLiner catheters are intended to be used in conjunction with guide catheters to access discrete regions of the coronary
`and/or peripheral vasculature, and to facilitate placement and exchangeof guidewires and other interventional devices.
