Many of these lesions recur and the artery has another obstruction within a short period. This occurs in 40 percent of angioplasties within six months after PTCA. A stent is a short hollow tube. It is placed in the artery at the site of the former blockage. It holds the artery open. Initially, bare metal stents were used. Compared with no stents, re-obstruction rates at six months after angioplasty were cut in half, to 20 percent, and few re-obstructions were seen more than a year after treatment. Drug eluting stents, or DES, were developed to try to further reduce the rate of re-obstruction. These stents are metal with a polymer coating and a drug, either sirolimus or paclitaxel, mixed into the polymer. The drug is delivered to the area of the opened artery over a period of up to a year.
