Originally developed as a less invasive alternative to emergency thoracotomy with aortic cross clamping, REBOA is performed to gain rapid control of non-compressible truncal or junctional hemorrhage. [1] [2] REBOA is performed first by achieving access to the common femoral artery (CFA) and advancing a catheter within the aorta. [1]
Blood flow through an artery is partially occluded by the deposition of an atherosclerotic plaque. 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.
The ABPI test is a popular tool for the non-invasive assessment of Peripheral vascular disease (PVD). Studies have shown the sensitivity of ABPI is 90% with a corresponding 98% specificity for detecting hemodynamically significant (stenosis of more than 50%) in major leg arteries, defined by angiogram. [3] However, ABPI has known issues:
Arteries have a superior long-term patency (expandedness), but veins are more commonly used due to their practicality. [40] Arterial grafts originate from the part of the internal thoracic artery (ITA) that runs near the edge of sternum, and can easily be mobilized and anastomosed to the native target vessel of the heart. The left artery is ...
Minimally invasive direct coronary artery bypass (MIDCAB) is a surgical treatment for coronary heart disease that is a less invasive method of coronary artery bypass surgery (CABG). [1] MIDCAB gains surgical access to the heart with a smaller incision than other types of CABG.
The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart.
In the transcaval approach a tube is inserted via the femoral vein instead of the femoral artery, and a small wire is used to cross from the inferior vena cava into the adjacent abdominal aorta. Once the wire is across, a large tube is used to place the transcatheter heart valve through the femoral vein and inferior vena cava into the aorta and ...
This mainly disrupts the organised thrombus and to a lesser degree presses it against the walls of the arteries. [9] This increases the size of the lumen of the arteries, thus opening them and allowing the blood flow to be restored. [9] The balloon is then deflated and removed. [8] A number of arteries can be treated during each BPA procedure. [8]
