Treatment for arterial occlusion varies depending on the extent of blockage. In severe cases, surgical intervention is needed to remove the blockage from the affected artery. Currently, there are 3 types of surgical approaches, including surgical bypass, endarterectomy, and embolectomy.
Atherosclerosis causes plaque to form within the carotid artery walls, usually at the fork where the common carotid artery divides into the internal and external carotid artery. The plaque build-up can narrow or constrict the artery lumen, a condition called stenosis. Rupture of the plaque can release atherosclerotic debris or blood clots into ...
Symptoms include chest pain or angina, shortness of breath, and fatigue. [6]A completely blocked coronary artery will cause a heart attack. [6] Common heart attack symptoms include chest pain or angina, pain or discomfort that spreads to the shoulder, arm, back, neck jaw, teeth or the upper belly, cold sweats, fatigue, heartburn, nausea, shortness of breath, or lightheadedness.
Patients with acute coronary syndrome and ST elevation are said to have ST-elevation myocardial infarction (STEMI) and they tend to have one of their coronary arteries totally blocked. [3] Damage is reversible for approximately 20 [ 4 ] -30 [ 5 ] minutes after complete obstruction of blood flow; thereafter myocardial cell death ensues and ...
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 ...
PCI involves placing a stent to relieve coronary artery blockages. [12] CABG involves grafting new blood vessels to provide a new route for blood flow around the blocked vessel. [12] Choice of treatment is based on the number of coronary vessels with blockages, which vessels are effected, and the medical history of the patient. [37]

Restenosis usually pertains to an artery or other large blood vessel that has become narrowed, received treatment to clear the blockage, and subsequently become re-narrowed. This is usually restenosis of an artery, or other blood vessel, or possibly a vessel within an organ. Restenosis is a common adverse event of endovascular procedures.
