Angioplasty and stent implantation
Angioplasty and stent implantation – a conventional and often-used procedure – opens up or widens a narrowed artery by using a catheter with a balloon on its tip. A stent is a scaffolding device that is placed in the artery to make sure it stays open.
Angioplasty and stent implantation is used to open many of the body’s arteries, including:
*Carotid artery stenting is a procedure that Swedish helped pioneer. A catheter is used to place a stent in one of the two main arteries in the neck after the artery has been narrowed by the build up of plaque. The procedure both improves blood flow to the brain and helps with the prevention of strokes. In the past, such blockages were treatable only with open surgery. To date, Swedish has performed the most carotid stent procedures in the Pacific Northwest.
Critical limb ischemia treatment
Treatment for critical limb ischemia (“cold leg” or “cold arm” syndrome) may vary from patient to patient, though the overall goal is always to reduce the pain and improve blood flow to save the limb and heal ulcerations and amputations. Most treatment plans will include medication to prevent further progression of the condition and reduce the effect of contributing factors such as diabetes, as well as medication for the pain.
One of several different endovascular procedures – including angioplasty, atherectomy (scraping the plaque off the artery), or thrombolysis to break up a blood clot – will be used to reopen the artery. More serious cases may require a bypass graft.
