Abstract: Objective:To discuss the value of transarterial embolization for postoperative hemorrage.Methods:Arterial angiography and transarterial embolization were performed in 13 patients with recurrent postoperative bleeding after surgery and biopsy,and efficiency of the operation was observed.Results:After angiography was perfomed in 13 patients,pseudoaneurysms were found in 6 patients,contrast medium extravasations were found in other 6 patients,and no abnomal arteriography was found in another 1 patient.Bleeding was controlled in 12 patients of the 13 patients after accepted transarterial embolization.Recurrent bleeding occurred in 1 patient of the 13 patients and it was not controlled after accepted transarterial embolization again for the reason of hemophilia.Conclusions:Transarterial embolization is safe,invasive and effective method for treatment of postoperative bleeding.
