A thoracic aortic aneurysm can grow slowly for years without causing symptoms. If one gets large enough, it can press on nearby organs or block blood flow and trigger pain in your back, chest, jaw or neck, or coughing, hoarseness or difficulty breathing.
Sometimes, a TAA can make the layers of your aorta tear and separate, creating internal bleeding. Doctors call this aortic dissection. Symptoms include:
- Shortness of breath
- Tearing or ripping pain in your chest
