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.
All interventions for carotid revascularization (carotid endarterectomy, carotid stenting, and transcarotid artery revascularization) carry some risk of stroke; however, where the risk of stroke over time from medical management alone is high, intervention may be beneficial. Carotid artery stenting and carotid endarterectomy have been found to ...
The carotid artery is the large vertical artery in red. The blood supply to the common carotid artery starts at the arch of the aorta (left) or the subclavian artery (right). The common carotid artery divides into the internal carotid artery and the external carotid artery. Plaque often builds up at that division, and a carotid endarterectomy ...
Screening for carotid artery narrowing has not been shown to be a useful test in the general population. [143] Studies of surgical intervention for carotid artery stenosis without symptoms have shown only a small decrease in the risk of stroke. [144] [145] To be beneficial, the complication rate of the surgery should be kept below 4%. Even then ...
Atherosclerotic plaque from a carotid endarterectomy specimen. An endarterectomy of the carotid artery in the neck is recommended to reduce the risk of stroke when the carotid artery is severely narrowed, particularly after a stroke to reduce the risk of additional strokes. [citation needed]
Carotid artery stenosis is caused by atherosclerosis whereby the buildup of atheromatous plaque inside the artery causes narrowing. Symptoms of carotid artery stenosis can include transient ischemic attack or stroke. Both symptomatic and asymptomatic carotid stenosis can be diagnosed with the aid of carotid duplex ultrasound which allows for ...
Rates of restenosis differ between devices (e.g., stent-grafts, balloon angioplasty, etc.) and location of procedure (i.e., centrally located in the heart, such as the coronary artery, or in peripheral vessels such as the popliteal artery in the leg, the pudendal artery in the pelvis, or the carotid artery in the neck). [citation needed]
Carotid artery stenting is a less invasive alternative to carotid endarterectomy for people with extra-cranial carotid artery stenosis. In this procedure, the surgeon makes a small cut in the groin and threads a small flexible tube, called a catheter, into the patient's carotid artery. A balloon is inflated at the site of stenosis, opening up ...
