Bilateral antegrade cerebral perfusion during hypothermic circulatory arrest before sternal reentry for aortic pseudoaneurysm repair.

Abstract

Sternal reentry for repair of aortic pseudoaneurysms poses a unique technical challenge to prevent exsanguination. Initiation of peripheral cardiopulmonary bypass and deep hypothermic circulatory arrest prior to reentry are the cornerstones of a successful surgical approach. Adjunctive bilateral antegrade cerebral perfusion increases safe arrest time and reduces neurologic morbidity. Herein, we describe our safe reentry technique for aortic pseudoaneurysm repair in two patients.
