We present a 45-degree two-stage venous cannula that confers advantage to the surgeon using cardiopulmonary bypass. This cannula exits the mediastinum under the transverse bar of the sternal retractor, leaving the rostral end of the sternal incision free of apparatus. It allows for lifting of the heart with minimal effect on venous return and does not interfere with the radially laid out sutures of an aortic valve replacement using an interrupted suture technique.
我们展示了一种45度的两阶段静脉插管,它为使用体外循环的外科医生带来了优势。该插管在胸骨牵开器的横杆下方离开纵隔,使胸骨切口的头端没有器械。它允许在对静脉回流影响最小的情况下提起心脏,并且不会干扰使用间断缝合技术进行主动脉瓣置换时呈放射状布置的缝线。
