Increase in graft blood flow in the early postoperative period.

Flow has been suitably measured by transit-time flow measurement, but measurements in the early period after cardiopulmonary bypass do not reflect expected values because of several factors. We documented that flow measurements during immediate revision of bleeding increased 3 times for the left internal thoracic artery and 2 times for the saphenous vein graft over previous measurements made after cardiopulmonary bypass in a patient who underwent coronary artery bypass surgery.
