深静脉血栓形成 中国就医指南

Deep Vein Thrombosis (DVT) is a serious hematologic condition characterized by the formation of a blood clot (thrombus) within a deep vein—most commonly in the lower extremities, such as the calf or thigh—but potentially affecting pelvic, upper limb, or abdominal veins. DVT arises from Virchow’s triad: venous stasis, vascular wall injury, and hypercoagulability. Pathophysiologically, endothelial damage (e.g., post-surgery or trauma), prolonged immobility (e.g., hospitalization, long-haul travel), or inherited/acquired thrombophilias (e.g., Factor V Leiden, antiphospholipid syndrome, cancer-associated coagulopathy) disrupt normal hemostatic balance, triggering platelet activation and fibrin deposition. Untreated DVT carries a high risk of pulmonary embolism (PE)—a life-threatening complication where the clot dislodges and obstructs pulmonary arteries—and may lead to post-thrombotic syndrome (PTS), marked by chronic leg pain, swelling, skin discoloration, and ulceration due to venous valve incompetence and microcirculatory dysfunction. Epidemiologically, DVT affects approximately 1–2 per 1,000 adults annually worldwide, with incidence rising sharply after age 40 and doubling every decade thereafter. In China, population-based studies estimate an annual incidence of 0.05–0.15%, though underdiagnosis remains common. Key modifiable risk factors include major surgery (especially orthopedic or abdominal), prolonged immobilization (>72 hours), active malignancy, pregnancy/postpartum state, hormonal therapy (e.g., oral contraceptives, HRT), obesity (BMI ≥30), smoking, and chronic conditions like heart failure or inflammatory bowel disease. Non-modifiable risks include advanced age, personal or family history of VTE, and certain genetic mutations. DVT significantly impairs quality of life: patients frequently report persistent fatigue, activity limitation, anxiety about recurrence or PE, sleep disruption, and reduced work productivity. PTS develops in up to 40% of symptomatic DVT cases within two years, contributing to long-term disability and healthcare burden. Early diagnosis—via clinical assessment (e.g., Wells score), D-dimer testing, and confirmatory compression ultrasonography—is critical. Delayed recognition increases morbidity, mortality, and socioeconomic impact, particularly in aging populations and those with comorbid chronic diseases managed in hematology departments.
