Abstract
In interventional radiological history, the first percutaneous transluminal angioplasty (PTA) was attempted by the renowned radiologist Dr. Dotter. Recently, almost all procedures are performed with not only balloon PTA but also further techniques. But this balloon PTA is still one of the basic interventional techniques along with stenting or transarterial embolization, so now we often draw on this technique for periprocedures of stent placement, or dilatation for in-stent stenosis.
In principle, we cannot avoid a vascular accident like an elastic recoil or dissection, or long term restenosis. Therefore, we could use a newly designed balloon for an area like the lower popliteal one as it is one of the most difficult locations in which to place a stent.
In this article, we would like to explain the structure, principle and basic technique of the balloon PTA. In addition we have reviewed new balloon techniques including the cutting balloon, cryoplasty, and drug eluting balloon.
