Venous thromboembolism after hepatic resection: analysis of 5,706 patients.
OBJECTIVE: The routine use of venous thromboembolism (VTE) chemoprophylaxis after hepatic surgery remains controversial due to the relatively low incidence of this complication and the significant risk of perioperative bleeding. The objective of our analysis was to identify perioperative predictors of postoperative VTE in patients undergoing resection. METHODS: All patients from the American College of Surgeons National Surgical Quality Improvement Program Participant User File from 2005 to 2009 who underwent hepatic resection were included for analysis. Forward stepwise multivariate logistic regression models were used to determine perioperative variables that are significantly associated with VTE after hepatic surgery. RESULTS: The overall incidence of VTE after hepatic resection was 2.9 %. Significant predictors of VTE after hepatic resection included preoperative mechanical ventilation, male gender, operative time > 3 h, age ≥ 70 years, intraoperative transfusion, and extended hepatectomy. Several non-VTE postoperative complications were also associated with subsequent VTE, including prolonged mechanical ventilation, need for early reoperation, and postoperative bleeding. CONCLUSIONS: Many perioperative factors, including extended hepatectomy as well as several postoperative non-VTE complications, are associated with an increased risk of VTE after hepatic resection. Knowledge of these factors may assist surgeons in deciding which patients merit more aggressive prophylaxis against this complication.
