Abstract
Background: The position of thoracic endovascular aortic repair (TEVAR) compared to open surgery of the thoracic aorta has changed. This study evaluates outcomes after TEVAR performed electively using our original Matsui-Kitamura stent graft (MKSG) to treat descending thoracic aortic aneurysms (dTAA) and chronic type-B aortic dissection (type-B AD), and elucidates the risk factors for postoperative spinal cord ischemia (SCI). Methods: TEVAR was performed using an MKSG in 66 patients (age: 70.8 ± 9.2 years). The underlying etiology was atherosclerotic change in 39 patients, chronic type-B aortic dissection in 23 patients, and other in 4 patients. Results: No perioperative deaths occurred. Three patients showed temporary paralysis due to postoperative SCI. Abdominal aortic aneurysm (AAA) surgery was a risk factor for postoperative SCI (p = 0.04). The 5-year survival rate was 81.2 %. Conclusion: The present study demonstrated that TEVAR of patients with dTAA and chronic type-B AD using an MKSG can be performed with high technical success rates and low rates of severe acute complications. AAA surgery was a risk factor for postoperative SCI.
