Incidence and independent risk factors of lower extremity deep vein thrombosis in patients with acute carbon monoxide poisoning: a retrospective study

Lower extremity DVT is relatively common in ptients with acute carbon monoxide poisoning. Coma duration, D-dimer levels, and delayed initiation of hyperbaric oxygen therapy are significantly associated with increased risk. The proposed risk factor model demonstrates strong predictive value and may assist in early clinical detection and targeted prevention strategies.
