・バイパス術で最も重要なのは「長期のpatency」であるが，「虚血合併症の回避（遮断時間の短縮）」も同様に重要である．

・術野設定を含めた吻合操作前の準備が，バイパス術成功のカギとなる．

・すべてのステップで完璧な手技を行うことを意識し，確認を怠らないことが重要である．

　The primary objective of bypass surgery is the long-term patency of bypass vessels, but shortening occlusion time during anastomosis is also required to avoid ischemic complications. Bypass surgery is associated with variations in the procedure depending on a surgeon's preference. However, regardless of technical variations, success of bypass surgery depends on some universal aspects. Surgical field preparation before anastomosis and implementation of adequate steps for confirmation of the procedure are important determinants of a successful bypass surgery.
