Abstract
This report describes the novel parachute technique of open distal anastomosis at the aortic arch replacement. Two Teflon felt cylindrical collars were initially placed on the anastomotic site of the descending aorta. All four to five outer loops of the stitches used in the parachute technique were tracked by the gathering suture. The anastomotic sutures and three gathering sutures were finally pulled simultaneously. The prosthetic graft and the aortic stump with Teflon felt were safely and completely anastomosed. Surgical or hospital death and serious complications were not found. The mean anastomotic duration (circulatory arrest duration) in 16 patients was 23 minutes. Our novel technique using a Teflon felt cylindrical collar and modified continuous suturing was not only safe but also reduced the duration of anastomosis and minimized blood loss. This technique is simple and can be applied to aortic valve replacement.
