RESUMEN
OBJECTIVES: The prominence of "enhanced recovery after surgery" (ERAS) protocols being adopted in thoracic surgery requires a re-evaluation of mechanical venous thromboembolism (VTE) prophylaxis guidelines. The goal of this study was to assess the role of sequential compression devices (SCD) in the prevention of VTEs such as deep vein thrombosis and pulmonary embolism (PE) in thoracic surgical patients. METHODS: We identified 200 patients who underwent elective oncological thoracic surgery between December 2018 and December 2020 in 2 cohorts-1 with SCDs and 1 without (i.e. non-SCD). All patients followed a standardized enhanced recovery after surgery (ERAS) protocol. The quality of care provided by SCDs was evaluated by the incidence and severity of postoperative and follow-up VTEs. Cohorts were compared by the Caprini score (CS) and the Charlson Comorbidity Index (CCI) with a two one-sided t-test analysis. Secondary outcomes include perioperative characteristics and follow-up data. RESULTS: Only 2 patients within the SCD group developed a PE with average CS and CCI metrics, both after hospital discharge and treated with anticoagulants, raising concern over the prophylactic nature of SCDs. The CS (6.9 ± 1.3 and 6.9 ± 1.5; P = 0.96) and the CCI (3.8 ± 2.0 and 4.1 ± 2.6; P = 0.33) for non-SCD and SCD, respectively, did not differ. The two one-sided t-test analysis for CS (P < 0.001) and CCI (P < 0.001) demonstrated equivalence. CONCLUSIONS: Although larger studies are required to confirm these results, routine SCD use may not be required when implementing ERAS protocols because clinically significant VTE rates were minimal.
