Isovolemic hemodilution in a patient with polycythemia vera undergoing deep hypothermic circulatory arrest.

摘要

To the Editor: Polycythemia vera (PV) is a disorder of the multipo-tent progenitor hematopoetic cell, characterized by increased production of crythrocytes, white blood cells and platelets.1 Patients with PV present with ischemic attacks to various organs related to blood hypervlscosity and decreased blood flow. Deep hypo-thermic circulatory arrest (DHCA) further increases the risk of thrombotic complications. A patient with PV requiring DHCA has never been reported. We describe the management of a patient with PV undergoing cardiac surgery requiring DHCA using isovolemic hemodilution.
