Sirolimus Coated Angioplasty Balloon in the Salvage of Thrombosed Arteriovenous Graft

"Sirolimus has been used in organ transplantation as well as coronary stent due to its antiproliferative properties. It has been proven to has better outcome in animal studies compared to paclitaxel, which is about 22% in the sirolimus group versus 75% re-stenosis rate in paclitaxel group.~Sirolimus is coated on the surface of the angioplasty balloon and is transferred to the vessel wall when balloon is inflated and in contact with the vessel wall.~The following table compare sirolimus to paclitaxel. In which sirolimus works by cytostatic mechanism with a ten thousand fold of safety margin. And sirolimus's anti-restenosis effect is optimal with the benefit of lower level of competition and lesser tissue absorption and elution."
