A review of follow-up outcomes after elective endovascular repair of degenerative thoracic aortic aneurysms

Long-term outcomes of elective thoracic endovascular aortic repair (TEVAR) for degenerative thoracic aortic aneurysms (TAA) are not well defined. A review of the literature on the follow-up outcomes of elective TEVAR for degenerative TAA resulted in 22 relevant articles. Two- and five-year freedom from aneurysm-related death varied between 93.0% and 100.0%, and 82.4% to 92.7%, respectively. Two-year and five-year all-cause survival ranged between 68.0% and 97.2% and 47.0% to 78.0%, respectively. Follow-up ranged between 17.3 and 66.0 months. Most common endograft-related complication was endoleak, with reported rate between 1.4% and 14.8% during six months up to five years of follow-up. Endovascular reinterventions were reported in 0.0–32.3%, secondary open surgery was needed in 0.0% to 4.7% during follow-up. Aneurysm-related survival rates after elective TEVAR for degenerative TAA are acceptable. However, reported incidences of endograft-related complications vary considerably in the literature, but the majority can be managed with conservative treatment or additional endovascular procedures.
