- W2617635072 abstract "Delayed paraplegia (DP) following thoracoabdominal or descending thoracic aortic (TAA/DTA) repair is a dreaded complication. We reviewed our experience with the management of DP using our previously described COPS protocol (blood-pressure stabilization, cerebrospinal-fluid (CSP) draining and O2-delivery). Complete documentation of hourly CSP pressures and detailed hemodynamic variables were available since 2000. A case-control design was used to analyze the extensive hourly data in the perioperative period. Data were analyzed by contingency-tables, t test, and regression analysis, as appropriate. Between 2000 and 2011, we performed 1059 TAA/DTA repairs. Of these, 47 (4.4%) had DP and 31 (2.9%) had immediate neurologic deficit. Postoperatively, renal replacement therapy and drain complications were significantly associated with DP. Variation in systolic blood pressure (SBP) was also highly predictive. Similarly, spinal-cord perfusion pressure (SCPP = SBP ? SP) showed increased risk with greater variability closer to event day (OR 1.3, P = 0.009). Fluctuation of more than 15 mmHg in SBP in a 24-hour period was associated with 3.2-fold increased odds of DP (P = 0.004). In all, 8/47 (17%) made a full recovery, whereas 19 (40%) had partial recovery by discharge. The 30-day mortality was 18/47 (38%) in DP and 7/55 (13%) in controls (P < 0.001). Long-term survival was significantly lower among DP cases (5-year survival of 28% vs. 75%, P < 0.001). DP occurs infrequently and is predictably associated with intraoperative loss of MEP, postoperative renal replacement therapy, drain complications and unstable systolic and spinal-cord perfusion pressures. Increased vigilance is recommended for patients who experience any of these events." @default.
