Abstract
Pre-operative embolization of hypervascular spinal tumors can be helpful in tumour resection; however, few studies have been reported on its effectiveness in sacral tumors. We aimed to investigate the value of surgical excision with pre-operative transarterial embolization for primary sacral tumors and evaluate the long-term follow-up outcomes. Data were obtained from a consecutive series of 60 patients (33 female, 27 male) who had sacral tumors and who, between 1992 and 2007, underwent surgical excision in conjunction with arterial embolization. The evaluation parameters included intraoperative blood loss, transfusion, treatment, local recurrence and complications associated with surgery. All tumor masses were resected without intraoperative shock or death. The mean intraoperative blood loss was 1168.3mL (range: 200-5700mL) and the mean transfusion amount was 5.2 units (range: 0-35 units). Radical wide excision was performed on eight patients, marginal excision was conducted for 34 patients and intralesional excision was undertaken for the remaining 18 patients. The mean follow-up period was 75.2months (range: 15-180months). Nineteen (31.7%) patients developed local recurrences. Of the patients who had at least the second sacr...Continue Reading
