[Two Methods of End-to-side Parachute Anastomosis].

There are two methods of end-to-side parachute anastomosis. For a quick end-to-side anastomosis, the graft and artery are placed in parallel proximity and 5 parachute stitches are performed. There are type A that moves the needle inside to outside the artery and type B that moves inside to outside the graft. Each has its advantages. In type A, complications such as dissection do not occur because the needle is always moved from the inside of the artery. Type B is faster because the first few parachute stitches are done by forehand. However, if arteriosclerosis is severe, there is a risk of dissection. Therefore, it is important to use both types appropriately.
