Novel Technique for Aortic Arch Surgery Under Mild Hypothermia

Extended mild hypothermic aortic surgery†

“…Total arch replacement is also possible under whole body antegrade perfusion [5], by placing a Medtronic DLP© venous cannula (Y-ed from the arterial line) through the tube graft into the distal aorta for antegrade lower body perfusion (see figure available at: http://ats.ctsnetjournals.org/content/vol85/issue1/ images/large/347.S0003497507013525.gr1.jpeg). The brain and lower body are continuously perfused with the exception of a very limited circulatory arrest time (6-8 min) of the lower body, which only represents the time necessary for resection of the aortic tissues, positioning of the cuffed DLP cannula in the descending aorta and the inflation of the occlusion balloon.…”
