Aortic cross-clamp
Aortic Cross-Clamp
The Aortic Cross-Clamp (pronunciation: /eɪˈɔːrtɪk ˈkrɒs klæmp/) is a surgical instrument used in cardiovascular surgery to clamp the aorta, the main artery in the human body, to prevent blood flow during certain procedures.
Etymology
The term "Aortic Cross-Clamp" is derived from the combination of "aorta", the large main artery that carries blood from the heart to the rest of the body, and "cross-clamp", a term used to describe the action of clamping across a tube or vessel.
Usage
The Aortic Cross-Clamp is primarily used in open heart surgery, specifically during coronary artery bypass grafting (CABG), aortic valve replacement, and aortic aneurysm repair. The clamp is applied to the aorta, effectively stopping the flow of blood and allowing surgeons to operate on a bloodless field. This is often necessary for procedures that require the heart to be stopped, such as CABG.
