Total arch replacement (TAR) for aneurysm of the aortic arch through the midsternotomy has several advantages over left thoracotomy. The purpose of this study was to identify the factors that might have an effect on the distal anastomosis through midsternotomy. From October 1999 to August 2005, 125 patients underwent TAR for aneurysm of the aortic arch through midsternotomy. Ninety-four patients with antegrade cerebral perfusion were selected. Distal anastomosis was performed under circulatory arrest (CA) of the lower body. Preoperatively, the diameter of aneurysm, the depth of distal end of aneurysm from anterior skin surface and the anteroposterior diameter of body trunk were measured. Postoperatively, the distance from the carina to the distal anastomosis was measured. There were six early deaths (6.4%). Duration of CA was 37±7.6 min. Diameter of the aneurysm was 60.6±13.2 mm and the depth of the distal end of aneurysm was 139±20.6 mm. There was no correlation between CA time and these factors. The anteroposterior diameter of body trunk was 200±18.0 mm and has a correlation with CA time. The depth of distal end of aneurysm from anterior skin surface was the only factor that affected duration for distal anastomosis.
