Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [1] [2] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia. [1]
The ABI is a simple, non-invasive test that measures the ratio of systolic blood pressure in the ankle to the systolic blood pressure in the upper arm. This is based on the idea that if blood pressure readings in the ankle are lower than those in the arm, a blockage in the arteries that provide blood from the heart to the ankle is suspected. [55]
A vein from the leg is removed and grafted to the coronary artery to bypass a blockage at LAD. Coronary artery bypass surgery during mobilization (freeing) of the right coronary artery from its surrounding adipose tissue (yellow). The tube visible at the bottom is the aortic cannula, which returns blood from the heart–lung machine.
Based on the BASIL trial, the ACCF/AHA guidelines recommend balloon angioplasty only for patients with a life expectancy of 2 years or less or those who do not have an autogenous vein available. For patients with a life expectancy greater than 2 of years life, or who have an autogenous vein, a bypass surgery could be performed first. [8]

Acute blockage (embolism) of a blood vessel by a thrombus that has detached from its place of formation (on the wall of a vessel) and entered the circulating blood. As a result of this blockage, blood flow in the vessel stops—a condition called thromboembolism. [1] Thromboembolism is a condition in which a blood clot breaks off from its ...
Vasodilators to relax and dilate blood vessels. [1] Appropriate drug treatments successfully produce thrombolysis and removal of the clot in 50% to 80% of all cases. [1] Antithrombotic agents may be administered directly onto the clot in the vessel using a flexible catheter (intra-arterial thrombolysis). [1]
An imaging dye is loaded into the blood vessel through the catheter and the movement of the dye in the blood vessel is recorded as an angiogram. [18] Doctors could determine if there are any abnormalities in the blood vessel using fluoroscopy, computed tomography (CT) angiography or magnetic resonance (MR) angiography. After the catheter is ...
