Advantage of Echo guided wiring
1. Echo guided wiring is a safe procedure.
2. It leads to a decrease of Radiation dosage as well as shortening
the Fluoroscopy time.
3. It is easy to get the true lumen.
4. It enables us to perform the true lumen angioplasty.
5. We cannot use Debulking device without the technique of true
lumen angioplasty when it is released.
6. The DCB effect to the pseudo lumen angioplasty is not yet known.
Drawbacks of Echo guided wiring.
1. Sonographer is vital to perform Echo guided wiring.→ Sonographer is not necessarily required. → Because Doctor can do the same procedure.
2. We cannot detect the high quality image without Hi-end machine. → There is no other way but to purchase the machine.

Take home message
I believe that the Intraluminal approach is safer than the subintimal approach in
using the Debulking device.
Duplex ultrasound guide wiring is an easier procedure to get the Intra plaque
angioplasty, and I strongly recommend you to master this procedure.
