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 ...
Coronary endarterectomy involves removing atheroma from the wall of blocked blood vessels (coronary) supplying the heart muscle. The concept was first introduced by Bailey [2] in the 1950s prior to the advent of coronary artery bypass surgery to help patients with angina and coronary artery disease. It is still used today when coronary artery ...
The surgeon attaches one end of the new vessel right before the blockage, and the other end in the area after the affected portion. [13] This reestablishes proper blood flow toward the desired area. Steps of performing an endarterectomy on the carotid artery, in which the accumulated atheroma is removed via surgery.
In July 1980, Houston Astros starting pitcher J.R. Richard collapsed while playing a game of catch, and was found to have experienced a stroke due to severe blockage of his right carotid artery. Given the fact that shortly beforehand, he had been found to have near-total obstruction of the arteries supplying his right arm, he was eventually ...
Carotid artery dissection is a serious condition in which a tear forms in one of the two main carotid arteries in the neck, allowing blood to enter the artery wall and separate its layers (*dissection*). This separation can lead to the formation of a blood clot, narrowing of the artery, and restricted blood flow to the brain, potentially ...
The common carotid artery is the large artery whose pulse can be felt on both sides of the neck under the jaw. On the right side it starts from the brachiocephalic artery (a branch of the aorta), and on the left side the artery comes directly off the aortic arch.
In the neck, the artery issues branches to the digastric muscle, stylohyoid muscle, sternocleidomastoid muscle, and the parotid gland. [1]In the neck, the posterior auricular artery issues the stylomastoid artery which enters the stylomastoid foramen to provide arterial supply to the facial nerve (CN VII), tympanic cavity, mastoid air cells of the mastoid antrum, and the semicircular canals.
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.
