Contact Admin. Surgical treatment of the ascending aorta and aortic arch with antegrade cerebral perfusion and moderate hypothermia. Twelve consecutive adult patients who presented with proximal aortic dissections or aneurysms were operated on.
Of these, seven presented with aortic dissections and five presented with ascending aortic or aortic arch aneurysms. Arterial perfusion was achieved using an 8. There were no neurological or bleeding complications.
In ten cases, the aortic valve was preserved by resuspension or remodeling. The mean time of circulatory arrest with antegrade cerebral perfusion was 24 minutes range from 20 to 35 minutes. Thoracic aortic diseases present with significant morbidity and mortality rates and are considered the most complex aortic diseases, causing severe consequences when treatment is not performed in time or when it is inadequate.
There have been great advances in the treatment of these diseases with the evolution of imaging techniques, bringing substantial improvements to surgical results and consequently, survival of patients.
In DeBakey et al. These authors described the excision of the dilated section, joining of the separated layers and restoration of the aortic blood flow with an end-to-end anastomosis.
