Aortic dissection is a rare entity with an incidence estimated to be 5-30 cases per million people per year. It is more common in patients with hypertension, connective tissue disorders, congenital aortic stenosis or bicuspid aortic valve, and in those with first-degree relatives with history of thoracic dissections. Spontaneous dissections are rare. We describe one such case who was treated successfully with a endovascular stent graft without any local or systemic complication.
