Thoracic endovascular aortic repair (TEVAR): a focus on complications

Thoracic endovascular repair (TEVAR) has emerged as a valid alternative for thoracic aortic aneurysm repair as it is less invasive. Recent systematic review and meta-analysis of comparative studies found that TEVAR, compared to open surgery, may reduce early death, paraplegia, renal insufficiency, transfusions, reoperation for bleeding, cardiac complications, pneumonia, and length of stay. This review will address some of the reported complications after this procedure. These include: mortality, stroke, spinal cord ischemia, retrograde dissection, device malfunction, access complications, endoleak, and migration.
