Methods that minimize preoperative bleeding in hypevascular metastatic tumors

Background and Aim : Hypervascular metastatic tumors sometimes cause serious bleeding in surgery. This issue may not allow total excision of the tumor. Preoperative tumor embolization is beneficial for reducing intraoperative blood loss in patients with vascular tumors. So here we want to express methods that minimize preoperative bleeding according to such studies.Methods : This study was searched in data bases like PubMed, Science direct, Sid,… with key words Preoperative Bleeding, Tumor Embolization, Hypervascular tumors between 2014-2018.Results : Such studies have said Trans catheter Arterial Embolization (TAE) is useful way for reduce blood loss during surgery also have emphasized on Ethyl Alcohol (EA) injection for decrease bleeding. Both are decreasing bleeding through intraoperative when used before surgery.Conclusion : Since the blood losing is significative to patient health we should use this method for tumor devascularization. Preoperative TAE clinically effective to minimize bleeding also EA is an easy, cheap and less invasive method.
