Research Progress on Assessment of Blood Supply of Spinal Tumors and Methods of Reducing Intraoperative Blood Loss / 肿瘤防治研究

ABSTRACT

In order to avoid the intra- and post-operative risks caused by massive blood loss, there are various clinical methods for evaluating the blood supply of the tumor and the distribution of blood vessels around the tumor before surgery, such as dynamic enhanced CT, dynamic enhanced magnetic resonance imaging, digital subtraction angiography, etc. And there are a variety of pre- and intra-operative methods to reduce tumor bleeding, such as transarterial vertebral tumor embolization, percutaneous or transpedicular injection of Onyx/NBCA, antifibrinolytic drugs, controlled deliberate hypotension, etc. This article reviews on spinal tumor blood supply assessment and the methods to reduce the amount of surgical bleeding.
