STUDY DESIGN: Prospective cohort study. PURPOSE: There has been no research examining the use of intraoperative cell salvage during metastatic spinal surgery. The present work is a pilot study investigating the role of cell salvage during metastatic spine surgery. OVERVIEW OF LITERATURE: There is no spinal literature about role of cell salvage and autologus transfusion in metastatic spinal cancer. METHODS: Sixteen spinal metastases patients who received red cell salvage using a leucocyte depletion filter were enrolled. Of these, ten patients who received salvaged blood transfusion were included in the final analysis. Data collection involved looking at the case notes, operating room records and the prospectively updated metastatic spinal cancer database maintained in the spinal department. Cell salvage data was recovered from the central cell salvage database maintained in the anesthetic department. RESULTS: Amount of salvaged blood ranged from 120 to 600 mL (average, 318 mL). The average drop in hemoglobin was 1.65 units (range, 0.4-2.7 units). Three patients (30%) required postoperative allogenic blood transfusion. The average follow up was 9.5 months (range, 6-6 months). One patient developed new lung metastasis, at seven months. No patient developed new liver metastases. Preoperatively, six patients had diffuse skeletal metastases. Of this subgroup, three developed new skeletal metastases. No cases showed any wound related problems in the postoperative period. CONCLUSIONS: In our study transfusion of intraoperatively salvaged blood did not result in disseminated metastatic cancer. We would suggest that red cell salvage might have a role during metastatic spine surgery.

STUDY DESIGN: Modern biomaterials and instrumentation have popularised surgery of the thoraco-lumbar spine through an anterior route. The advantage of anterior surgery is that it allows for a direct decompression of the compromised spinal canal. However, the potential for devastating long-term sequelae as a result of complications is high. PURPOSE: The aim of this study was to give a general overview and identify the incidence of vascular complications. OVERVIEW OF LITERATURE: There is limited literature describing the overall incidence and complications of anterior spinal surgery. METHODS: A retrospective review of a prospective database of 1,262 consecutive patients with anterior surgery over a twelve-year period. RESULTS: In our study, 1.58% (n=20) of patients suffered complications. Injury to a major vessel was encountered in 14 (1.11%) cases, of which nine involved an injury to the common iliac vein. In six cases, the original procedure was abandoned due to a life-threatening vascular injury (n=3) and unfavourable anatomy (n=3). CONCLUSIONS: The incidence of vascular and other complications in our study was relatively low. Nevertheless, the potential for devastating long-term sequelae as a result of complications remains high. A thorough knowledge and awareness of normal and abnormal anatomy should be gained before attempting such a procedure, and a vascular surgical assistance especially should be readily accessible. We believe use of access surgeons is mandatory in cases with difficult or aberrant anatomy.
