[Recent progress in adjunctive methods during surgery of aortic dissection].

Abstract

Aortic dissection is severe disease, but recently surgery of aortic dissection is reported in good results. In order to improve results, three adjunctive methods have been progressed recently; intraoperative color Doppler retrograde cerebral perfusion and deep hypothermia. Intraoperative color Doppler reveals dynamic hemodynamics and structural information in aortic dissection in real time which leads to proper surgical treatment to obtain maximum effects with minimum invasiveness. To carry out thrombus obliteration in false lumen by informations of intraoperative color Doppler leads to a healing in aortic dissection. Retrograde cerebral perfusion during surgery of aortic dissection permitted simple procedure and good surgical results with reduced neurological complications. Deep hypothermia for protection of spinal cord and other organs also yielded good operative results and reduced rate of paraplegia.
