摘要
Abstract
Objective To evaluate the safety and value of preoperative transarterial embolization of hypervascular vertebral tumors. Methods Sixteen patients with hypervascular vertebral tumors underwent transarterial embolization before surgery. The lesions were located between the middle cervical and lower lumbar spine. Forty-one arteries were embolized with permanent particles injected through a microcatheter, including polyvinyl alcohol (PVA) particles (150-500 μm) in 25 arteries and Dextran particles (150-350 μm) in 16. Of these, 31 had pieces of gelatin sponge added for proximal pedicled embolization. The criteria for judging the effectiveness of embolization were completeness of tumor removal and estimated blood loss during surgery. Results The particles were injected into the tumor feeders through superselection in 17 arteries or flow control in 24. Tumor embolization was defined as "total" in five patients, "nearly total" in eight, "subtotal" in two, and "partial" in another. There were no symptomatic complications associated with embolization. Tumors were entirely removed in all patients. The average estimated blood loss during surgery was 1510 ml (range of 200-6000 ml) for all 16 patients.Conclusion Preoperative embolization of hypervascular vertebral tumors is safe and effective. It can make complete resection of a tumor possible and can make a previously unresectable tumor resectable. Superselection or flow control is necessary to achieve effective devascularization and to avoid complications.关键词
