Thoracic endovascular aortic repair with a right thoracotomy approach

Abstract

Abstract Background The common femoral artery is usually the preferred access route for thoracic endovascular aortic repair (TEVAR). However, if access from the common femoral artery is challenging, other routes must be considered. We report a case of TEVAR performed by approaching the descending thoracic aorta with a right thoracotomy and using the descending thoracic aorta as an access route. Case presentation A 70-year-old female was diagnosed with a descending thoracic aortic aneurysm (65 mm in diameter), a thoracoabdominal aneurysm (54 mm in diameter), and an abdominal aortic aneurysm (49 mm in diameter). Since the patient had severe chronic obstructive pulmonary disease, one-stage replacement of the thoracoabdominal aortic aneurysm was contraindicated and TEVAR on the descending aorta was selected. A strong tortuous section of the aorta—from the descending aorta to the abdominal aorta—hampered endovascular access to the site from the common femoral artery. A TEVAR approach from the abdominal aorta was also considered; however, an abdominal aortic aneurysm and a transverse colon loop stoma from an earlier surgery presented challenges to this technique. We chose to access the descending thoracic aorta with a thoracotomy from the right 6th intercostal space for TEVAR, because the access route that is not affected by the meandering of the aorta is considered to be the descending aorta with a right thoracotomy. The patient’s postoperative course was uneventful after the stent graft was placed. No complications were detected with postoperative contrast-enhanced computed tomography (CT). Conclusions Our findings suggest that TEVAR can be performed by approaching the descending aorta from a right thoracotomy, if variations of vascular anatomy interfere with the more commonly used femoral artery approach.
