Could you please give us an update on the "cutting balloon" use for venoplasty since your first use in March when it was like "butta". Is there a higher risk of thrombus and should more follow-up be given to check by ultrasound when it is used? Dr. Gary Siskin did discuss this in his lecture at the SUNY conference Aug. 2010. There is no published guidance for the use of this device in veins with MS disease and I would like to hear about development of a standard for using the cutting balloon. Veins can be much weaker than arteries are they not? Dissection is a risk with venoplasty, and what benefits does the cutting balloon have? Very few have been proven in cardiac artery uses. Please help. This is becoming a hot trend on the west coast. Thanks....
the cutting balloon "scores" the lining of the vein and also increases the forcefullness of the balloon dilatation. it basically results in a higher pressure effect on the balloon.
i used it because the stiff valves were so difficult to distend. with a standard balloon. i used it as a precursor to larger balloon dilatation.
alas, there are no standards at all, biggest problem we have in evaluating liberation. i hope that those using devices will report their experience as some point. but without an irb oversite, they cannot
dissection of veins is a rare condition, perforation is more common. dissection is a tear in the wall with blood dissecting the layers of the blood vessel. it is not seen often in veins, only arteries, where intimal dissections are more common during angioplasty
