Answer

During aortoiliac reconstruction, the downward flush is a maneuver in which, following the proximal and one distal anastomosis, a gush of blood is allowed to escape through the unanastomosed limb of the prosthesis, while the other artery is clamped, to remove debris. In a variation on this technique, one group was able to prevent peripheral emboli during aortoiliac reconstruction with the placement of a blood filter and perfusion cannula between the unanastomosed limb and unattached distal artery, allowing a larger gush of blood and more atheromatous debris to be flushed out.
