Best Doctor List Near You for Carotid Artery Stenting in Porto alegre

Carotid artery stenting (CAS) is a minimally invasive procedure designed to treat carotid artery stenosis, a condition characterized by the narrowing of the carotid arteries due to atherosclerosis, which can lead to reduced blood flow to the brain and increase the risk of stroke. The procedure involves the insertion of a stent, a small mesh tube, into the narrowed carotid artery to help maintain its patency after it has been opened. The process typically begins with the patient receiving local anesthesia and sedation to ensure comfort during the intervention. A catheter is then inserted into the femoral artery in the groin and guided up to the carotid artery using fluoroscopic imaging for real-time visualization. Once the catheter reaches the site of the stenosis, a balloon catheter may be used to temporarily inflate and widen the narrowed segment of the artery. This is followed by the deployment of the stent, which expands against the walls of the artery and acts as a scaffold to keep it open. Carotid artery stenting can be performed either as a stand-alone procedure or after an angioplasty, depending on the severity of the blockage and the specific anatomy of the patient's carotid arteries. The procedure is generally favored in patients who are at significant risk of complications from traditional carotid endarterectomy, particularly those with high surgical risk due to medical comorbidities, advanced age, or anatomical challenges. After the stenting, patients often require medication to prevent blood clots from forming around the stent, typically including antiplatelet agents such as aspirin or clopidogrel. The success of carotid artery stenting is evaluated through imaging studies that assess blood flow in the carotid arteries, and close follow-up is necessary to monitor for any potential complications such as restenosis, stroke, or other vascular issues. While CAS is generally considered safe, it does carry risks, including the possibility of embolization of plaque debris, which can lead to transient ischemic attacks (TIAs) or strokes during the procedure. Long-term outcomes have shown that when performed in properly selected patients, carotid stenting can significantly reduce the risk of stroke and improve quality of life. Patients undergoing this procedure are often advised on lifestyle modifications, such as diet control, regular exercise, and smoking cessation, to further decrease their risk of cardiovascular events. With advancements in technology and techniques, carotid artery stenting has become an established therapeutic option and is performed in specialized vascular centers by experienced interventional radiologists or cardiologists. This innovative approach continues to evolve, incorporating new stent designs and delivery systems that enhance patient safety and improve clinical outcomes, ultimately contributing to the effective management of carotid artery disease and reducing the associated risks of stroke and other complications.
