Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally-invasive procedure performed during resuscitation of critically-injured trauma patients.. 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 hemorrh
Where P Leg is the systolic blood pressure of dorsalis pedis or posterior tibial arteries and P Arm is the highest of the left and right arm brachial systolic blood pressure. The ABPI test is a popular tool for the non-invasive assessment of Peripheral vascular disease (PVD).
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 Windkessel analogy illustrated. Windkessel effect (German: Windkesseleffekt) is a term used in medicine to account for the shape of the arterial blood pressure waveform in terms of the interaction between the stroke volume and the compliance of the aorta and large elastic arteries (Windkessel vessels) and the resistance of the smaller arteries and arterioles.
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 ...
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
These give rise to coronary arteries: [4] [better source needed] The left aortic or left posterior aortic sinus gives rise to the left coronary artery; The right aortic or anterior aortic sinus gives rise to the right coronary artery; The posterior aortic or right posterior aortic sinus usually gives rise to no vessels.
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.
