I71: Aortic aneurysm and dissection

I71.0: Dissection of aorta [any part]

Dissection of the aorta, categorized under ICD-10 code I71.0, is a serious heart condition where there's a tear in the inner layer of the aorta - the large blood vessel branching off the heart. This tear enables blood to flow between the layers of the aortic wall, forcing the layers apart, and is called aortic dissection. This condition may lead to deadly complications if the blood-filled channel ruptures through the outside aortic wall. The onset of aortic dissection often presents with severe, sudden chest pain. Some people may describe it as a tearing or ripping sensation, most commonly felt in the chest or the back. It's a medical emergency that, while relatively rare, most often occurs in men in their 60s and 70s. Understanding its signs and symptoms can lead to quick diagnosis and treatment, which is crucial for survival.
