Excessive oozing through the fabric of the branched Cryolife-Jotec Evita Open NEO hybrid prosthesis.

We report 3 cases of excessive oozing after aortic arch replacement using the frozen elephant trunk technique through the fabric of the branched Cryolife-Jotec Evita Open NEO hybrid prosthesis. After weaning from cardiopulmonary bypass, protamine administration as well as standard substitution of plasmatic and cellular coagulation adjusted to thrombelastometry, excessive oozing persisted leading to a complicated postoperative course in all 3 patients.
