Distal anastomosis in total arch repair for type A acute aortic dissection is difficult because of fragile aortic wall and time-limiting procedure. Until 2008, distal anastomosis was performed with continuous suture technique at 20 , and parachute technique with 4-stay sutures at 26 - was introduced in our institution. This new technique was compared with previous distal anastomosis with continuous suture technique. From May 1997 to December 2010, 40 patients underwent emergent arch repair for type A acute aortic dissection. Continuous suture technique was used in 23 patients (group C) and parachute technique with 4 stay-sutures was used in 17 patients( group P). Patient's demographics did not differ between the 2 groups and there was no difference in perioperative or hospital death in the 2 groups. Lower limb ischemic time, cardiac ischemic time, cardiopulmonary bypass time and operation time were significantly shorter in group P. Distal anastomosis using parachute technique with 4-stay sutures in arch repair for type A acute aortic dissection seems to be useful compared with continuous suture technique.
