Comparison of fibrin-emboli in porcine brain sections during hypothermic cardiopulmonary bypass (CPB). (A) Fibrin-emboli per area (given as the square root of fibrin thrombi for all brain sections divided by the total sectional area [in cm2]) and (B) total number of brain emboli. ATH, antithrombin-heparin covalent complex; and UFH, unfractionated heparin. Results are mean ± SD.
