Recent single-center reports demonstrate a high (up to 10%) incidence of postoperative venous thromboembolism (VTE) after major vascular surgery. Moreover, vascular patients rarely receive prolonged prophylaxis despite evidence that it reduces thromboembolic events after discharge. This study used a national, prospective, multicenter database to define the incidence of overall and postdischarge VTE after major vascular operations and assess risk factors associated with VTE development. ⋯ Postoperative VTE is associated with the type of vascular procedure and is highest after operations in the chest and abdomen/pelvis. About 40% of VTE events in elective vascular surgery patients were diagnosed after discharge, and the presence of VTE was associated with a quadrupled mortality rate. Future studies should evaluate the benefit of DVT screening and postdischarge VTE prophylaxis in high-risk patients.

Multicenter Study
Risk prediction of 30-day readmission after infrainguinal bypass for critical limb ischemia.
Hospital readmission after lower extremity bypass is a large cost burden and has become a focal point for policy change directed at disease-specific bundling strategies. The purpose of this study was to evaluate rates and predictors of 30-day readmission from a large, multicenter trial data set. ⋯ Readmission after lower extremity bypass for CLI is common (24%). Certain characteristics, such as female gender, current smoking, dialysis-dependence, tissue loss, and in-hospital graft-related events, are associated with increased risk. Readmission is associated with long-term limb loss. These data provide benchmark values for this complex patient population and may prove useful when hospital readmission is used as a quality metric for hospital performance.
