Preoperative target arterial embolization for vertebral tumor / 介入放射学杂志

ABSTRACT

Objective To discuss the clinical value of preoperative embolization of vertebral tumors. Methods Data of 54 patients were retrospectively studied. Thirteen lesions were in the cervical, 17 in the thoracic, 15 in the lumber and 9 in the sacral regions. The vertebral tumors were embolized prior to operation with gelatin sponge particles, polyvinyl alcohol (PVA) particles or coils. Surgical operations were performed within 1-7 days after the embolization. Results Totally 79 vessels of 43 patients were embolized, which included ascending cervical artery,1;vertebral artery,1;intercostal artery,39; lumber artery,19;internal iliac artery,15 and median sacral artery,4. Intraoperative hemorrhage showed a mean value of 1312 ml with range of 300-3000 ml in patients after embolization, and a mean value of 2375 ml with range of 1500-5000ml in patients without embolization at the same period(P
