Stent obstruction: Blockage can occur, repeating symptoms or other complications. Stent related pain: Chest or throat pain may occur after the procedure; requiring additional treatment or adjustment of the stent. Stent removal: Check with your doctor on the stent type used for the procedure. Ask if it may need to be removed at a later date and ...
A 6-month follow up post-implantation of the radioactive stents showed little adverse side-effects in the patients. [6] However, more recent studies have shown that patients have a late progression of in-stent neointimal hyperplasia after 1 year of radioactive stent implantation, suggesting a delay in the development of neointimal hyperplasia ...
Diagram of stent placement. In A, the catheter is inserted across the lesion. In B, the balloon is inflated, expanding the stent and compressing the plaque. In C, the catheter and deflated balloon have been removed. Before-and-after cross sections of the artery show the results of the stent placement. Arterial Stenting 3D Medical Animation
After placement of a stent or scaffold, the patient needs to take two antiplatelet medications (aspirin and one of a few other options) for several months to help prevent blood clots. The length of time a patient needs to be on dual antiplatelet therapy is individualized based risks of ischemic events and bleeding risk. [29]
A drug-eluting stent (DES) is a small mesh tube that is placed in the arteries to keep them open in the treatment of vascular disease.The stent slowly releases a drug to block cell proliferation (a biological process of cell growth and division), thus preventing the arterial narrowing that can occur after stent implantation.
If restenosis occurs within a stent (also known as in-stent stenosis), it may be treated with repeated angioplasty and insertion of another stent inside the original, often with a drug-eluting stent. [14] Over the past 5 years, ISR has been increasingly treated with a drug-coated balloon (DCB), which is a balloon coated with the same anti ...
Patients are typically able to walk within two to six hours following the procedure and return to their normal routine by the following week. [31] Angioplasty recovery consists of avoiding physical activity for several days after the procedure. Patients are advised to avoid heavy lifting and strenuous activities for a week.
Carotid artery stenting is an endovascular procedure where a stent is deployed within the lumen of the carotid artery to treat narrowing of the carotid artery and decrease the risk of stroke. It is used to treat narrowing of the carotid artery in high-risk patients, when carotid endarterectomy is considered too risky.
