Treatment of Spinal Metastases with Epidural Cord Compression through Corpectomy and Reconstruction via the Traditional Open Approach versus the Mini-Open Approach: A Multicenter Retrospective Study

Figure 4

The perioperative outcomes. The open group had a significantly greater average estimated blood loss, blood transfusions of red blood cells and fresh frozen plasma, hospital stay, and complications than the mini-open group (p < 0.05). The average operation time in the open group was significantly shorter than that in the mini-open group (p < 0.001).
