✦ Synopsis

Background and Objectives: Pelvic tumors are often large and difficult to excise with appropriate surgical margins due to their size, proximity to neurovascular structures, and major intraoperative bleeding. The purpose of this study is to evaluate the yield of preoperative angiography and embolization so as to facilitate achievement of good surgical results. Methods: Eighteen patients who suffered from large pelvic tumors (average size, 10.7 cm × 8.3 cm × 3.7 cm), 15 primary and 3 metastatic, underwent surgery at our institution between 1990 and 1995, after preoperative angiography and embolization of the tumors. Results: The efficacy of the procedure was high. In all but one patient, the grade of vascularity of the tumor was reduced by at least two levels (based on our new tumor vascularity scale. In most patients, appropriate surgical margins were achieved. The average perioperative blood loss was only 750 cc. Procedure-associated complications were negligible.

Conclusions:

The results of this study call for the use of angiography and embolization in the management of patients with large pelvic tumors.
