Visceral protection during moderately hypothermic selective antegrade cerebral perfusion through right brachial artery.

Objective: This study investigates distal organ protection during moderately hypothermic right brachial artery selective antegrade cerebral perfusion (MHSACP) in patients undergoing aortic arch repair.

Methods: Fifty patients undergoing ascending aorta/aortic arch repair using the MHSACP technique (study group) were compared with another 50 patients randomly selected amongst those undergoing moderately hypothermic open heart procedures (control group). The data from successive clinical examinations and blood samplings were then compared to detect any sign of distal organ damage attributable to the MHSACP technique.
