Use of preoperative vascular embolisation in spinal metastasis resection.

Preoperative selective embolisation was carried out on 17 patients with spinal metastases from various primary tumours. There was a significant reduction in the blood loss (2088 ml) and infusion volume requirement (3500 ml) and more favourable postoperative haemoglobin (Hb) development compared with the non-embolised but otherwise identical control group. The reduced intraoperative bleeding manifested itself in the form of greater clarity and a less complicated intraoperative course. Particularly with a dorsal approach, the reduced bleeding permitted more exact preparation and more extensive tumour resection. Preoperative embolisation is thus a valuable aid in spinal metastasis resection. Given suitable indications and exact positioning of the embolising material, no significant complications should arise. The method as a whole calls for close collaboration between interventional radiologists and spinal orthopaedists.
