Key result
Left subclavian artery cannulation and sequential aortic reconstruction achieved encouraging preliminary results in decreasing the time of hypothermic circulatory arrest and cerebral ischemia.
Why the study?
Total arch replacement remains associated with high risks of stroke and paraplegia, largely due to prolonged hypothermic circulatory arrest and cerebral ischemia.

Left subclavian artery cannulation with sequential aortic reconstruction may reduce hypothermic circulatory arrest time and associated ischemic risks during total arch replacement.
Despite many technical improvements, total arch replacement is still associated with a high risk of stroke and paraplegia, which is largely ascribed to the long duration of hypothermic circulatory arrest (HCA) and cerebral ischemia.1 We have optimized our current total arch replacement technique2,3 by using left subclavian artery (LSA) cannulation and sequential aortic reconstruction to decrease the time of HCA and cerebral and spinal cord ischemia, which has achieved encouraging preliminary results.
