It was reported that a dissection occurred that may have been caused by the charger balloon, requiring additional intervention.
A charger balloon dilatation catheter was selected for use in the superficial femoral artery (sfa).
The anatomy was moderately tortuous at the transition from the femoral artery to the sfa with moderate calcification and 70% stenosis.
A 0.
035" guidewire and a non-bsc 6f guide sheath were used in this procedure.
While attempting to advance a 5mm x 60mm x 130cm innova stent to the proximal sfa, the distal edge of the stent caught on the proximal edge of a newly deployed 5mm x 150mm innova stent and failed to cross.
The innova device was removed.
No damage to either stent was observed.
Percutaneous transluminal angioplasty (pta) was performed on the proximal edge of the previously deployed innova stent with the charger balloon.
A dissection occurred that may been caused by the charger balloon or a laser.
An angiogram was not taken between the use of the laser and pta to confirm the cause of the dissection.
The 5mm x 60mm x 130cm innova stent was then re-inserted and again failed to cross the proximal edge of the previously deployed innova stent.
The innova device was removed.
A non-bsc stent was then selected for use and successfully crossed the stent to treat the proximal sfa stenosis.
The dissection was treated by stenting, and no additional patient complications were reported.
