Objective: The estimate cerebral blood flow with trascranial doppler in right brachial artery perfusion during hypotermic circulation arrest during the correction of aortic arch aneurysms and dissections.

Material and Methods: Ten patients (mean age of 52±8,3 years) were monitored. We monitored maximum blood flow velocities of bilateral middle cerebral arteries using the transcranial doppler (Multi-Dop T, Oxford Medical) at four periods: after induction of anestesia, during cardiopulmonary bypass, during antegrade cerebral perfusion and after termination of cardiopulmonary bypass. Also we used trascranial doppler monitoring with embol detection.
