Aortic Dissection is more common than you think. It causes 3,000 deaths a year in the UK - more than road traffic accidents. Our patient charity is a driving force in efforts to improve diagnosis and treatment
Aortic dissection occurs when an injury to the innermost layer of the aorta allows blood to flow between the layers of the aortic wall, forcing the layers apart, as shown in the diagram above.
- In most cases, this is associated with a sudden onset of severe chest or back pain, often described as "tearing" in character. Also, vomiting, sweating, and lightheadedness may occur.
- Other symptoms may result from decreased blood supply to other organs, such as stroke, lower extremity ischemia, or mesenteric ischemia.
Aortic dissection can quickly lead to death from insufficient blood flow to the heart or complete rupture of the aorta.
Key to the prevention of aortic dissection is blood pressure control and smoking cessation.
