Branched graft inversion technique for distal anastomosis in total arch replacement.
Distal anastomosis during total arch replacement for thoracic aortic aneurysm is at times difficult, and bleeding from it is a serious problem because of its limited surgical exposure. We have modified a new procedure, the branched graft inversion (BGI) technique. We investigated the effectiveness of our technique by comparing it with the conventional stepwise technique. Between January 2008 and August 2011, 40 patients, divided into two groups of 20 each, underwent elective total arch replacement. One group underwent surgery using BGI; the stepwise technique was performed on the remaining 20 patients. Our modified BGI technique offers easy and secure distal anastomosis under good surgical procedure, resulting in shorter durations of operation, cardiopulmonary bypass, and circulatory arrest (455.1±101.3 min versus 354.7±49.3 min, p<0.001; 248.2±46.6 min versus 199.7±28.2 min, p<0.001; 76.6±27.7 min versus 61.6±10.4 min, p=0.029, respectively). As a result, this technique could be a useful in performing total arch replacement.
