The best treatment for any aneurysm that is longer than 6 cm is a major surgery to replace the aorta with a fabric graft, as stated by MedlinePlus. The surgical procedure involves cutting the left side of the person's chest, and there is a greater chance of the cut reaching the abdomen.
The standard treatment for a thoracic aneurysm is the open-chest approach, as stated by Cleveland Clinic. The main purpose of the treatment is to replace the weakened part of the aorta with a graft. The fabric graft is made from a material that is stronger than the weakened aorta. This procedure is usually complicated and requires an experienced surgical team.
An aneurysm is an unusual widening of a part of the artery, which results from weakness in the wall of the blood vessel. A thoracic aortic aneurysm usually affects a portion of aorta, the largest artery in the heart. The most common cause of this condition is atherosclerosis, hardening of the arteries. This condition usually affects patients with long-term hypertension, those with high cholesterol and smokers. Risk factors for thoracic aneurysm include syphilis, advanced age, aorta inflammation, connective tissue disorders and injuries sustained from falls and accidents.
