We are grateful for the kind comments by Dr Pocar and colleagues. In our comparison of 2 groups of patients, 20 underwent left heart bypass (LHB) and 39 had total circulatory arrest (TCA). Despite use of no adjunct, postoperative paraplegia decreased from 1 in 20 patients (5%) who underwent LHB to 1 in 39 patients (2.6%) who underwent TCA.1 Although this difference is not significant (P>.99), it does remain below the published series of patients who received spinal fluid drainage.2
There were no significant differences in stroke rate (P = .65) that occurred in 1 of 20 patients (5%) undergoing LHB vs 4 of 39 patients (10%) in the TCA group; however, we have observed a lower trend when the aorta is not manipulated, particularly around the aortic arch area during bypass.
Subsequent to aortic arch anastomosis, it is crucial to switch arterial cannula to the . . . [Full Text of this Article]
