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 ...
Cerebral Hyperperfusion Syndrome leading to stroke is a serious complication of carotid artery angioplasty with stenting. [27] Angioplasty may also provide a less durable treatment for atherosclerosis and be more prone to restenosis relative to vascular bypass or coronary artery bypass grafting. [28]
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 ...
It was first performed on a subsartorial artery in 1946 by a Portuguese surgeon, João Cid dos Santos, at the University of Lisbon. In 1951, E. J. Wylie, an American, performed it on the abdominal aorta. The first successful reconstruction of the carotid artery was performed by Carrea, Molins, and Murphy in Argentina, later in the same year.

In 1948, Radner [4] published one of the first descriptions of transradial central arterial catheterization and attempts at coronary artery imaging using radial artery cut-down. Transradial access to perform diagnostic cardiac catheterization procedures was introduced by Campeau [ 5 ] and was later adapted for therapeutic procedures of coronary ...
To image the vessels of the neck such as common carotid, internal and external carotid arteries, AP, lateral, and 45 degrees bilateral oblique positions are taken. Contrast injection rate is 3 to 4 ml/sec with total volume of 7 to 9 ml. The frame rate of fluoroscopy is 3 to 4 frames/sec. [8]
This is primarily done on the carotid arteries (Carotid endarterectomy or CEA) but was first performed on the superficial femoral artery. While not performed on coronary arteries, it is mentioned here for completeness. Stenting: Enlarging the lumen of an artery by forcibly expanding it with a metal wire tube by means of catheterization ...
