Treatment of a thoracic aortic aneurysm is essential to reduce the risk of complications, mainly the risk of a rupture that can be lethal. The treatment depends on its size and rate of expansion, its location and shape, the symptoms and your overall physical condition.
It can be watchful waiting with medical treatment, endovascular minimally invasive repair or open surgical repair. All three options have a place in contemporary practice and your vascular surgeon will guide you towards the best option.
As a general rule a thoracic aortic aneurysm more than 5.5 or 6 cm is considered large and needs to be treated operatively. Elective treatment is individualized for every patient, taking into account all the aforementioned factors. In case of rupture emergent operative management open or endovascular is needed as a life-saving procedure.
