Cerebral Protection in Ascending Aorta and Aortic Arch Repair

Abstract

Cerebral protection during procedures involving repair of ascending and thoracic aorta remains a problem to the present day. During any of this procedures a period of interruption or exclusion of cerebral circulation has proved to be an indispensable addition in this surgery to prevent enbolization to the brain during such manipulation some surgical procedures have been introduced to avoid such neurologic complications. Intaoduclion of deep hypothermic circulatory arrest have revolutionized surgical treatment of thoracic aortic pathology in the last two decades. However cumulative clinical experience haalso shown that protection afforded by deep hypothermic circulatory arrest alone is not quiet perfect. Therefore the search for an ideal strategy of cerebral protection continues this strategies included retrograde cerebral perfusion with deep hypothermic circulatory arrest and antegrade selective cerebral perfusion this review of literatures will show the surgical techniques of cerebral protection and physiology of brain protection and neurological after each procedure of cerebral protection.
