XO Score® Clinical Results

Critical Arterial Stenosis
Low-pressure dilatation in the iliac and common femoral arteries using XO Score resulting in successful revascularization and stent placement.

Pre-treatment Iliac and Common Femoral Arteries

XO Cross treatment

Post-treatment Iliac and Common Femoral Arteries

Post-treatment kissing stents placed
Critical Stenoses in Brachiocephalic Hemodialysis Fistula Patient
Multiple critical stenotic lesions in a brachiocephalic hemodialysis fistula patient. Each of the three treatment sites was successfully treated at low PTA inflation pressure using a standard off-the-shelf balloon inside the XO Score.


Pre-treatment venous outflow and central arch stenosis


XO Score treatment
No cinching or waisting present


Post-treatment

Juxta-anastomotic Stenosis in Tortuous Brachiocephalic Fistula
Tortuosity and low-pressure <5ATM deployment using XO Score without vessel straightening.

Juxta-anastomotic stenosis (inflow)

Treatment using XO Score

Post XO Score result
Flow restored with no residual stenosis
Edge Stenosis in Occluded Stent Graft
Dilatation of edge stenosis using XO Score on an occluded dialysis stent graft.

Pre-treatment angiogram

Controlled lesion dilatation using XO Score

Post XO Score treatment

Critical In-flow Anastamotic Stenosis
XO Score used across arterial anastomosis with low 4 ATM pressure to achieve controlled lesion dilatation.

Juxta-anastomotic stenosis (inflow)

Treatment using XO Score

Post-treatment inflow restored
