A Case Report of Aortic Arch Replacement for Acute Dissection of Stanford Type A under 135 Minutes of Deep Hypothermic Circulatory Arrest Employing Retrograde Cerebral Perfusion / 日本心臓血管外科学会雑誌

ABSTRACT

A 54-year-old male with sudden back pain was diagnosed as having acute aortic dissection of Stanford type A. He underwent an aortic arch replacement under the deep hypothermic circulatory arrest and retrograde cerebral perfusion. During retrograde cerebral perfusion, the central venous pressure was maintained at 20mmHg, the perfusion flow rate was 400ml/min and the lowest rectal temperature was 19°C. The duration of retrograde cerebral perfusion was 135 min, but the patient recovered successfully without any evidence of neurological complications. This report suggests that retrograde cerebral perfusion associated with deep hypothermic circulatory arrest has the possibility to prolong the safety time limit of antegrade cerebral circulatory arrest up to 135min.
