Endovascular stenting with open surgery for reconstructions of the ascending aorta and the aortic arch: A review of indications and results of hybrid techniques

摘要

Hybrid approaches for repair of aneurysms involving the ascending aorta and the aortic arch have been developed to avoid or reduce duration of cardiopulmonary bypass and circulatory arrest and to decrease operative time, blood loss, hospital stay, morbidity, and mortality. These include ascending aorta-based debranching or cervical extra-anatomical bypasses followed by stent-grafting. In patients with associated descending aortic aneurysms, the elephant trunk technique is used followed by stent-grafting of the descending thoracic aorta. A review of the literature of hybrid aortic arch reconstructions, published over past 7 years, reveals perioperative mortalities from 0% to 13%, stroke from 0% to 10%, and spinal cord injury in 0% to 13%. The outcomes are comparable to contemporary results from total open and total endovascular reconstructions in spite of the fact that the hybrid approach is generally taken in patients with high surgical risk for open repair and with prohibitive anatomy for total endovascular repair.
