Abstract
We very much appreciate the opportunity to analyze the manuscript by Zipfel and colleagues [1]. They have stated that prophylactic subclavian artery revascularization may reduce significant neurologic complications. They concluded that prophylactic reconstruction of subclavian artery is safer than later elective reconstruction after stent graft repair of thoracic aorta disease. However, the authors demonstrated no statistical difference in neurologic complications between the patients in the protected and unprotected series.
