BACKGROUND: Our aim is to describe our method of central venous cannulation in minimally invasive cardiac surgery using a novel device which facilitates easy tunneling of the venous cannula. METHODS: Our technique includes using a standard double-stage venous cannula with a 3/8" connection site. After completing ministernotomy pericardiotomy is performed and aorta is cannulated using the Seldinger technique. Direct right atrial cannulation is performed in a conventional fashion. Afterward, our device* (Fig. 1) is connected to the back end of the venous cannula. Then a strong thread is sewn to the tip of the device. A 2.5-cm incision is performed in the 5-6th intercostal space. Pulling the thread with a clamp the cannula is guided through the intercostal space out of the chest. RESULTS: Comparing with existing approaches, our technique has several advantages. Firstly, it frees the wound from the cannula making it more comfortable for a surgeon than conventional central venous cannulation. Also, it provides a better exposition of the aortic root. In addition, it does not require an additional groin access and thus helps to avoid complexity and local complications of femoral cannulation. CONCLUSIONS: The device enables safe, fast and convenient central venous cannulation for minimally invasive cardiac surgery. *Non-FDA approved. Patent pending.
