An Experimental Study on Transplantation of the Aortic Arch

Part H. Transplantation of the Aortic Arch under Severe Hypothermia (Rectal Temperature 18.5°-14°C)

Abstract

The author transplanted the aortic arch with homologus grafts under long cessation of the blood flow from the heart as one of the applications of severe hypothermia which is presently studied by Watanabe et al. at this clinic. The blood flow of the heart was interrupted for a long time, 60-140 minutes, at rectal temperature 18.5°-14°C. Five of 18 survived the operation with successful outcome. Anastomosis could be carried out without tension and fear of massive blood loss, and it had the advantage to perform careful operation.
