Comparison of preoperative and postoperative CT chest. Preoperative CT chest had a Haller index of 8.7. The anterior-posterior diameter minimum preoperatively was 3 cm (a). Postoperative CT chest had a Haller index of 11.3 (b). The anterior-posterior diameter minimum postoperatively was 2.3 cm. Example of a normal chest CT Haller index (c), with lines demonstrating measurements of the Haller index (ratio of A/B).

These demonstrated no active sources of bleeding, no pneumothoraces, and a relatively unfilled, hyperdynamic left ventricle with a postoperative Haller index that increased from 8.7 to 11.3 (Figure 1).
Postoperative hemodynamics and fluid balance data include measurements of blood pressure (BP) in millimeters of mercury (mmHg) and include systolic BP, diastolic BP, and mean arterial pressure (MAP). Heart rate (HR) is presented in beats per minute. Cumulative input and output (I/O) is for the patient's entire hospital course and is presented in liters (L). Starting at one hour postoperative, the patient was approximately 6 liters positive. Crystalloid and colloid boluses are designated under the same title "bolus," which is identified by diamonds in the graphs. Vasopressor refers to any vasopressive medication given in the postoperative period and is designated by crosses. Vasopressin and ephedrine were given in the early postoperative period followed by a transition to norepinephrine alone at approximately 4 hours postoperative. Norepinephrine was administered in micrograms per kilogram per minute (mug/kg/min) and was stopped approximately 23 hours postoperative.

We utilized fluid boluses and vasopressor support over the course next 24 hours (Figure 2).
Preoperative and postoperative radiographs. The top two images are the preoperative standing posterior-anterior (a) and lateral (b) plain radiographs of the entire spine. The bottom two images are six-month postoperative standing anterior-posterior (c) and lateral (d) plain radiographs of the spine.
