An Optimized Preparation Platform for the Autologous Saphenous Vein Graft

Background: There is an unmet need to develop a device which can assist the operating surgeon in performing dexterous and proficient saphenous vein graft preparation. Methods: The device consists of a platform which bears a proximal port to secure the vein graft cannula, and a distal bulldog clamp which is used to occlude the distal end of the vein graft. In-between is a mobile base which holds a bulldog clamp and has the capacity to slide along a track that extends the entire length of the platform. This mobile bulldog clamp is used to isolate segments of the vein graft progressively starting from the vein inlet, thus keeping the vein graft filled under sufficient fluid tension. Results: We have evaluated the application of this device in over 800 patients and have found its use to facilitate proficient saphenous vein graft preparation. There were no incidents of unintentional saphenous vein graft injury or any other complication secondary to use of the device. Conclusions: The device was effective in vein graft preparation and maintaining graft orientation while requiring only simple modifications from current practice.
