Current research status of ionizing radiation bleeding syndrome / 中国辐射卫生

ABSTRACT

Bleeding caused by ionizing radiation involves many factors, the mechanism is complicated and the management is difficult. Bleeding is recognized as one of the main causes of death after ionizing radiation. In this paper, we summarize the pathophysiological mechanisms of ionizing radiation bleeding syndrome (IRBS) from the aspects of platelet abnormality, coagulation disorder and vascular damage. Besides, we expound the clinical characteristics of IRBS in terms of the degree, time and site of the bleeding. Combined with experimental results, we put forward ideas and possible approaches for the treatment of IRBS, and the key factor is to promote the recovery of megakaryocytes and rapid platelet production after radiation exposure.
