Are all antegrade cerebral perfusion techniques equal?
Congratulations to Urbanski et al. for their study [1]. We benefited a lot from this report. But we want to put emphasis on some points that—we think—should be taken into consideration by the authors. Antegrade cerebral perfusion technique is based on two factors: perfusion pressure and direction of the kinetic energy of pump output (2 l/min/m) during cooling down and warming up periods. Cannul...
متن کاملTotal arch replacement using bilateral axillary antegrade selective cerebral perfusion.
OBJECTIVE The prevention of cerebral injury is an important consideration during the repair of an aortic arch aneurysm, and this is a major goal of cerebral protection techniques. We describe extended thoracic aortic aneurysms treated by use of our current surgical strategy. PATIENTS AND METHODS From January 2001 to June 2008, a total of 17 patients (12 men and 5 women; mean age 67.3 ± 7.3 yr...
متن کاملBest strategy for cerebral protection in arch surgery - antegrade selective cerebral perfusion and adequate hypothermia.
Aortic arch surgery remains a complex surgical operation that necessitates specific neuroprotection strategies. Various approaches, such as hypothermic circulatory arrest (HCA), retrograde cerebral perfusion, and antegrade selective cerebral perfusion (aSCP), have each enjoyed periods of popularity. However, while the overall surgical approach tend to favour HCA with aSCP, technical factors, su...
متن کاملOptimal pH strategy for selective cerebral perfusion.
OBJECTIVE Selective cerebral perfusion (SCP) affords brain protection superior to hypothermic circulatory arrest (HCA) for prolonged aortic arch procedures. Optimal pH strategy for HCA is controversial; for SCP it is unknown. We compared pH strategies during SCP in a survival pig model. METHODS Twenty juvenile pigs (26+/-2.4 kg), randomized to alpha-stat (n=10) or pH-stat (n=10) management, u...
متن کاملEvolving arch surgery using integrated antegrade selective cerebral perfusion: impact of axillary artery perfusion.
OBJECTIVE The study objective was to determine the impact of integrated antegrade selective cerebral perfusion with right axillary artery perfusion during arch surgery. METHODS All surgeries were performed through a median sternotomy. Direct cannulation of the right axillary artery in the axilla was used for cardiopulmonary bypass and antegrade selective cerebral perfusion under hypothermia. ...
