Humeral head replacement in a hemophilia B omarthritis patient / 中国组织工程研究

ABSTRACT

BACKGROUND:In the past, the surgical treatment of patients with hemophilia B was difficult, the bleeding was difficult to estimate, and the wound healing was difficult. In the perioperative period, the control of coagulation factor IX activity in a safe range can ensure the safety of the operation, resulting in wel wound healing, good recovery, and no significant complications appeared in the long term. OBJECTIVE:To study essentials of perioperative diagnosis and treatment in omarthritis patients with hemophilia B undergoing humeral head replacement, and to analyze the importance on prognosis and rehabilitation. METHODS:The significance of surgical treatment for hemophilia B patients with arthritis, the prevention and treatment of perioperative complications were summarized through literature review. Humeral head replacement was conducted in a patient with hemophilia omarthritis by monitoring coagulation factor activity and infusing human prothrombin complex and frozen plasma. RESULTS AND CONCLUSION:(1) According to the monitoring, patients, whose coagulation factor IX activity increased from 7%to 50%, underwent humeral head replacement. (2) Within three days after replacement, coagulation factor IX activity was control ed>30%, 3 days-2 weeks>20%. No obvious complication was found after surgery. (3) These results suggested that hemophilia B arthritis was commonly treated by surgical treatment, which plays an important role in assessing patient’s condition and treatment. During perioperative period, replacement therapy of human prothrombin complex and control of coagulation factor activity in a appropriate range can effectively prevent postoperative complications.
