Case presentation

The patient was a 64-year-old moderately overweight (170 cm, 95 kg, body mass index 33) man with kyphosis scheduled for a revision posterior spine fusion. His past medical history was significant for hypertension, hypercholesterolemia, and multiple previous spine procedures for postoperative infection and pseudoarthrosis. Two years before this procedure, the patient underwent a sequential anterior–posterior thoraco-lumbar fusion, which was complicated by a postoperative pulmonary embolism (PE) requiring placement of an inferior vena cava (IVC) filter.

The current procedure consisted of a posterior re-instrumentation (T7 to the ileum), revision decompression (L3-S1), a posterior lumbar interbody fusion (L4-L5), and a pedicle subtraction osteotomy (L3). The 12-h procedure was associated with an estimated blood loss of 5,500 ml that required three units of packed red blood cells, 6 l of lactated Ringer solution, 1 l of 5% albumin, and 1,500 ml of cell scavenged blood cells
