Risk factors for postoperative venous thromboembolism in patients with lung cancer: a systematic review and meta-analysis

This meta-analysis confirmed that age ≥ 65 years, hyperlipidemia, advanced tumor stage (III-IV), thoracotomy, prolonged operation time (≥ 2 h), significant intraoperative blood loss (≥ 200 mL), abnormal D-dimer, and preoperative chemotherapy were risk factors for VTE in lung cancer patients after surgery. Targeted preventive measures based on these factors may help improve clinical outcomes in this patient population.
