Transient Ischemic Attacks (TIAs)
Angioplasty and stents placement
If people are not healthy enough to have surgery, angioplasty with stenting (see figure) may be done. For this procedure, a catheter with a balloon at its tip is threaded into the narrowed artery. The balloon is then inflated for several seconds to widen the artery. To keep the artery open, doctors insert a tube made of wire mesh (a stent) into the artery.
