Current status of thoracic aortic endograft repair.

The advent and success of endovascular repair of abdominal aneurysms had led to the development of catheter-based techniques to treat thoracic aortic pathology. Such diseases, including thoracic aortic aneurysms, acute and chronic type B dissections,penetrating aortic ulcers, and traumatic aortic transection, challenge surgeons to perform complex operative repairs in high-risk patients. The minimally invasive nature of thoracic endografting may provide an attractive alternative therapy especially in patients deemed unfit for thoracotomy. A worldwide review of thoracic endografting demonstrates encouraging short- and midterm outcomes with significant reductions in morbidity and early mortality.Long-term surveillance will be crucial to discover complications unique to thoracic endovascular interventions and to determine which patients are appropriate candidates for stent-graft therapy.
