Vertebral artery dissection is one of the two types of cervical artery dissection.The other type, carotid artery dissection, involves the carotid arteries.Vertebral artery dissection is further classified as being either traumatic (caused by mechanical trauma to the neck) or spontaneous, and it may also be classified by the part of the artery involved: extracranial (the part outside the skull ...
The American Heart Association also recommends screening if a physician detects a carotid bruit, or murmur, over the carotid artery by listening through a stethoscope during a physical exam. For people with symptoms, the American Heart Association recommends initial screening using ultrasound. [citation needed]
The carotid arteries are major blood vessels in the neck that branch into smaller vessels called the external and internal carotid arteries. [3] In carotid artery dissection, a tear in the arterial wall allows blood to flow between the layers of the artery, leading to potential narrowing, reduced blood flow, or clot formation, which may cause a ...

Carotid stenting involves the placement of a stent across the stenosis in the carotid artery. It can be performed under general or local anesthesia.. The stent may be placed from the femoral artery, radial artery, or from the common carotid artery at the base of the neck.
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]
As a result of this procedure, the distal end of the ITA is diverted to one of the coronary arteries (typically the LAD), facilitating blood supply to the heart. In the setting of increased resistance in the proximal subclavian artery, blood may flow backward away from the heart along the ITA, causing myocardial ischemia due to coronary steal.
The covered stent is composed of metal and is covered with Teflon (PTFE) or another sterile fabric-like material. The covered stent remains in place permanently, and the pseudoaneurysm, without a continuous flow of arterial blood, then thromboses. Advantages of this technique are that it has a high success rate without the need for an open surgery.
