Stent complications was improved as less common for medical technology. Newer stents coated with drugs, the so-called drug-eluting stents, the stent reduced the rate of complications to about 10 percent of the patients who need the procedure for clogged blood vessels. Older metal stents without medication showed a complication rate of about 20 percent, mainly as a result of arteries narrowing again after stents were implanted. A 2010 study investigating cranial stent complications showed 14.7 percent of patients suffered strokes within a month after the procedure, while only 5.8 percent of stroke victims exposed to other treatment options deceased.
Patients with atherosclerosis, a condition which occurs when fatty substances accumulate in the blood vessels, stents may receive via angioplasty procedures. During angioplasty, a small balloon device is screwed into an artery and inflated at the site of a blockage. This broadens it for a small mesh tube, or stent, which is left in the artery open. When coated stents first appeared on the market, occurred more complications. Since surgeons were experienced in using the machines the number of stent complications began to decline.
A negative effect of the procedure involves the formation of blood clots in the vicinity of the stent. This increases the risk of a stroke or a heart attack, but blood thinning medication would be to prevent the formation of blood clots. Bleeding can also occur on the spot when a catheter in the body, usually the groin, arm or wrist, but hemorrhaging is rare.
Patients with kidney problems may experience stent complications of the dye used to guide a surgeon to a blocked blood vessel. They can suffer an allergic reaction to the dye or experience organ damage and kidney disease exist. Medication can reduce the risk of tackling these.
Stent Complications occur when an artery is punctured during the procedure. This allows internal bleeding, leading to serious health problems. The rate of complications of arterial injury decreases as doctors gain experience in angioplasty.
When analyzing stent complications of intracranial stents, the researchers found a higher risk of bleeding in patients with stents implanted in the middle cerebral arteries. Blood clots leads to developed stroke within 30 days after angioplasty in some patients. Stents represent a form of treatment in the brains blocked arteries or carotid arteries in the neck which blood to the brains.
- Stent complications occur when an artery is perforated during an angioplasty procedure.
- Stents may be used in the carotid arteries, which is located in the neck.
- Stents are used to keep blood vessels free from clogging.
