Guidance/Advisory Criteria — Conditions

Acute Deep Vein Thrombosis

The commercial driver is at an increased risk for developing acute deep vein thrombosis (DVT) due to long hours of sitting as part of the profession. DVT can be the source of pulmonary emboli that can cause gradual or sudden incapacitation or death. Adequate treatment with anticoagulants decreases the risk of recurrent thrombosis by approximately 80%.
