Normal preoperative white blood cell count is predictive of outcomes for endovascular procedures

This study demonstrates a strong linear correlation between an increasing preoperative WBC within the normal range and an increased risk for postoperative complications and death following endovascular interventions. The study also found a significant curvilinear U-shaped relation between a normal preoperative WBC and death in the open surgical cohort, with patients in the very low and very high normal WBC range at an increased risk of death.
