Clinical Analysis of Huge Retroperitoneal Neurogenic Tumor Treated by Preoperative Endovascular Embolization / 实用放射学杂志

ABSTRACT

Objective To explore the initial clinical experiences of preoperative endovascular embolization of huge retroperitoneal neurogenic tumor.Methods 5 cases with retroperitoneal neurogenic tumor underwent endovascular embolization before operative resection since Aug.2006~May.2007.Digital subtraction angiography(DSA) was performed during processes in all cases and main tumor's vessels were embolized.Results The processes of endovascular embolization in 5 cases were successfully completed.0~400 ml blood were transfused in these cases.The tumors were excised completely in 4 cases and partly in 1 case.Conclusion Blood loss can be decreased by preoperative endovascular embolization for huge retroperitoneal neurogenic tumors.The extent of embolization should be performed according to individualization.
