The main purpose of this study is to assess the efficacy of precision preoperative embolization in decreasing operative blood loss, reducing surgical complications in pelvic tumor surgery. Furthermore the study aims at describing the vascularity in a series of pelvic tumors, and to correlate this with perioperative blood loss.
The main purpose of this study is to assess the efficacy of precision preoperative embolization in decreasing operative blood loss, reducing surgical complications in pelvic tumor surgery，which including poor wound healing，nerve injury，and pelvic organs dysfunction. Furthermore the study aims at describing the vascularity in a series of pelvic tumors,which contains four grade：poor，moderate，rich and abundant and to correlate this with perioperative blood loss.
